Page language: EN

Causes

  • Open or high-resistance wiring in coil C primary control circuit
  • Damaged or corroded coil connector or terminals
  • Failed ignition coil (internal primary open)
  • Blown fuse or faulty relay supplying coil power (if coil has fused supply)
  • Faulty PCM/ignition driver output
  • Poor grounds or battery supply to coil assembly

Symptoms

  • Malfunction Indicator Lamp (MIL) illuminated
  • Rough idle or engine misfire(s) under load
  • Loss of power, hesitation or poor acceleration
  • Increased fuel consumption and emissions
  • Possible hard starting or stalling
  • Intermittent operation if connector or wiring is intermittent

What to check

  • Read freeze frame and stored data with a scan tool; note related misfire codes
  • Visual inspection of coil C connector, wiring harness, pins, and ground points
  • Check engine fuses and relays related to ignition/coils
  • Wiggle test harness while monitoring live data for intermittent fault
  • Measure continuity and resistance of primary wiring between PCM and coil
  • Swap coil C with another cylinder's coil (if coils are interchangeable) to see if code follows coil

Signal parameters

  • Primary coil resistance typical range: ~0.2–3.0 ohms (manufacturer-specific; consult spec)
  • Secondary coil resistance typical range: ~4 k–30 k ohms (varies by design)
  • Control signal: switched pulse from PCM; low-side (to ground) switching or high-side depending on design
  • When cranking: control line should show pulsed switching at engine speed; steady open = open circuit
  • Battery supply to coil (if applicable): near battery voltage (11–14.5 V) with ignition ON/CRANK

Diagnostic algorithm

  1. Verify DTC: Clear code(s) and attempt to reproduce. Note if code is permanent or intermittent.
  2. Check for other related DTCs (misfire codes P03xx); observe freeze-frame and misfire counters to identify affected cylinder.
  3. Visual inspect coil C connector and wiring for damage, corrosion, pin push-out, or melted insulation.
  4. With ignition OFF, disconnect coil connector and measure primary coil resistance across coil terminals; compare to specification. An open or infinite resistance indicates a bad coil.
  5. Check continuity between the PCM coil control pin and the coil connector control pin; repair any open or high-resistance circuit.
  6. With a multimeter/voltmeter and ignition ON (engine OFF), verify power supply (if used) to the coil is ~battery voltage and ground is present. With engine cranking, verify control line pulses or switches as expected.
  7. Use an oscilloscope or lab scope to view the primary waveform at the coil while cranking/running: look for proper switching, trigger pulses, and absence of open-circuit flatline.
  8. Swap coil C with a known-good coil from another cylinder and rerun to see if the code follows the coil (fault moves => replace coil). If fault stays on same cylinder => suspect wiring or PCM.
  9. Inspect and test related fuses, relays, and grounds. Repair any damaged wiring, reconnect/clean terminals, and secure harness routing away from heat or abrasion.
  10. If wiring and coil are confirmed good and fault persists, consult manufacturer wiring diagrams and test PCM driver output; replace PCM only after exhausting wiring and component failures.

Likely causes

  • Broken/disconnected harness wire between PCM and coil C
  • Corroded or pushed-out pin at coil connector
  • Ignition coil internal failure (open primary winding)
  • Blown ignition fuse or faulty power distribution to coils
  • PCM driver transistor fault (less common)

Fault status

⚠️ Status
Ignition Coil C Primary Control Circuit/Open — the powertrain control module detected an open or abnormal condition in the low-voltage control circuit for ignition coil C. This may cause a misfire and illuminate the MIL.
🟡 Repair difficulty: Medium
⏱️ Diagnostic time: 0.5-2.0 hours

Brand: GWM
Type: P — Powertrain
Views: UK: 4 EN: 5 RU: 8
AI status
Completed

Completed 100%
Page language: EN

Causes

  • Open or high-resistance wiring in coil C primary control circuit
  • Damaged or corroded coil connector or terminals
  • Failed ignition coil (internal primary open)
  • Blown fuse or faulty relay supplying coil power (if coil has fused supply)
  • Faulty PCM/ignition driver output
  • Poor grounds or battery supply to coil assembly

Symptoms

  • Malfunction Indicator Lamp (MIL) illuminated
  • Rough idle or engine misfire(s) under load
  • Loss of power, hesitation or poor acceleration
  • Increased fuel consumption and emissions
  • Possible hard starting or stalling
  • Intermittent operation if connector or wiring is intermittent

What to check

  • Read freeze frame and stored data with a scan tool; note related misfire codes
  • Visual inspection of coil C connector, wiring harness, pins, and ground points
  • Check engine fuses and relays related to ignition/coils
  • Wiggle test harness while monitoring live data for intermittent fault
  • Measure continuity and resistance of primary wiring between PCM and coil
  • Swap coil C with another cylinder's coil (if coils are interchangeable) to see if code follows coil

Signal parameters

  • Primary coil resistance typical range: ~0.2–3.0 ohms (manufacturer-specific; consult spec)
  • Secondary coil resistance typical range: ~4 k–30 k ohms (varies by design)
  • Control signal: switched pulse from PCM; low-side (to ground) switching or high-side depending on design
  • When cranking: control line should show pulsed switching at engine speed; steady open = open circuit
  • Battery supply to coil (if applicable): near battery voltage (11–14.5 V) with ignition ON/CRANK

Diagnostic algorithm

  1. Verify DTC: Clear code(s) and attempt to reproduce. Note if code is permanent or intermittent.
  2. Check for other related DTCs (misfire codes P03xx); observe freeze-frame and misfire counters to identify affected cylinder.
  3. Visual inspect coil C connector and wiring for damage, corrosion, pin push-out, or melted insulation.
  4. With ignition OFF, disconnect coil connector and measure primary coil resistance across coil terminals; compare to specification. An open or infinite resistance indicates a bad coil.
  5. Check continuity between the PCM coil control pin and the coil connector control pin; repair any open or high-resistance circuit.
  6. With a multimeter/voltmeter and ignition ON (engine OFF), verify power supply (if used) to the coil is ~battery voltage and ground is present. With engine cranking, verify control line pulses or switches as expected.
  7. Use an oscilloscope or lab scope to view the primary waveform at the coil while cranking/running: look for proper switching, trigger pulses, and absence of open-circuit flatline.
  8. Swap coil C with a known-good coil from another cylinder and rerun to see if the code follows the coil (fault moves => replace coil). If fault stays on same cylinder => suspect wiring or PCM.
  9. Inspect and test related fuses, relays, and grounds. Repair any damaged wiring, reconnect/clean terminals, and secure harness routing away from heat or abrasion.
  10. If wiring and coil are confirmed good and fault persists, consult manufacturer wiring diagrams and test PCM driver output; replace PCM only after exhausting wiring and component failures.

Likely causes

  • Broken/disconnected harness wire between PCM and coil C
  • Corroded or pushed-out pin at coil connector
  • Ignition coil internal failure (open primary winding)
  • Blown ignition fuse or faulty power distribution to coils
  • PCM driver transistor fault (less common)

Fault status

  • Visual inspection of coil C connector, wiring harness, pins, and ground points
  • Check engine fuses and relays related to ignition/coils
  • Wiggle test harness while monitoring live data for intermittent fault
  • Measure continuity and resistance of primary wiring between PCM and coil
  • Swap coil C with another cylinder's coil (if coils are interchangeable) to see if code follows coil

Signal parameters

  • Primary coil resistance typical range: ~0.2–3.0 ohms (manufacturer-specific; consult spec)
  • Secondary coil resistance typical range: ~4 k–30 k ohms (varies by design)
  • Control signal: switched pulse from PCM; low-side (to ground) switching or high-side depending on design
  • When cranking: control line should show pulsed switching at engine speed; steady open = open circuit
  • Battery supply to coil (if applicable): near battery voltage (11–14.5 V) with ignition ON/CRANK

Diagnostic algorithm

  1. Verify DTC: Clear code(s) and attempt to reproduce. Note if code is permanent or intermittent.
  2. Check for other related DTCs (misfire codes P03xx); observe freeze-frame and misfire counters to identify affected cylinder.
  3. Visual inspect coil C connector and wiring for damage, corrosion, pin push-out, or melted insulation.
  4. With ignition OFF, disconnect coil connector and measure primary coil resistance across coil terminals; compare to specification. An open or infinite resistance indicates a bad coil.
  5. Check continuity between the PCM coil control pin and the coil connector control pin; repair any open or high-resistance circuit.
  6. With a multimeter/voltmeter and ignition ON (engine OFF), verify power supply (if used) to the coil is ~battery voltage and ground is present. With engine cranking, verify control line pulses or switches as expected.
  7. Use an oscilloscope or lab scope to view the primary waveform at the coil while cranking/running: look for proper switching, trigger pulses, and absence of open-circuit flatline.
  8. Swap coil C with a known-good coil from another cylinder and rerun to see if the code follows the coil (fault moves => replace coil). If fault stays on same cylinder => suspect wiring or PCM.
  9. Inspect and test related fuses, relays, and grounds. Repair any damaged wiring, reconnect/clean terminals, and secure harness routing away from heat or abrasion.
  10. If wiring and coil are confirmed good and fault persists, consult manufacturer wiring diagrams and test PCM driver output; replace PCM only after exhausting wiring and component failures.

Likely causes

  • Broken/disconnected harness wire between PCM and coil C
  • Corroded or pushed-out pin at coil connector
  • Ignition coil internal failure (open primary winding)
  • Blown ignition fuse or faulty power distribution to coils
  • PCM driver transistor fault (less common)

Fault status

⚠️ Status
Ignition Coil C Primary Control Circuit/Open — the powertrain control module detected an open or abnormal condition in the low-voltage control circuit for ignition coil C. This may cause a misfire and illuminate the MIL.
🟡 Repair difficulty: Medium
⏱️ Diagnostic time: 0.5-2.0 hours
