CHRYSLER P — Powertrain

Open Or Shorted Condition Detected In The Clutch Pedal Switch Override Relay Control

Brand: CHRYSLER
AI status
Completed
ready
Completed 100%
Page language: EN

Causes

  • Open or short in relay control wiring (broken conductor, chafing, pinched harness)
  • Corroded or loose connector at relay or module
  • Faulty clutch pedal switch
  • Faulty override relay (sticking coil or welded contacts)
  • Blown fuse or poor ground in related circuit
  • Faulty engine/control module driver output

Symptoms

  • Malfunction Indicator Lamp (MIL) or ECU warning lamp illuminated
  • Cruise control or clutch-interlock functions disabled
  • Starter interlock may not permit engine start (on some models)
  • Intermittent or no response from clutch pedal switch input

What to check

  • Scan for current and stored codes and view freeze-frame data
  • Visually inspect relay, connectors, and wiring for damage or corrosion
  • Check related fuses and grounds for continuity and tightness
  • Backprobe relay control circuit and observe voltage/continuity with clutch pedal operated
  • Swap relay with a known-good identical relay (if available) to test behavior
  • Check for intermittent faults by wiggling harness while monitoring signal

Signal parameters

  • Relay coil activation voltage: ~12 V (key on) when commanded by control module
  • De-energized: 0–0.5 V at control side for low/ground depending on design
  • Resistance of relay coil (typical): a few ohms to ~100 ohms (manufacturer spec required)
  • Expected continuity: control module pin to relay coil pin < 5 ohms (when connector present); open = infinite
  • No short to battery positive or ground when relay not energized (infinite/very high resistance)

Diagnostic algorithm

  1. Read and record DTCs and freeze-frame data with a scan tool. Note operating conditions when code set.
  2. Visually inspect relay, clutch pedal switch, connectors and wiring harness for damage, corrosion or loose pins.
  3. Check related fuses and chassis/engine grounds; repair any faults.
  4. With key ON (engine OFF), backprobe the relay control wire at the relay connector. Observe voltage while commanding the circuit with a scan tool (if possible) and while operating the clutch pedal. Compare to expected signal parameters.
  5. Measure continuity between the control module output pin and the relay control pin. Repair any opens or high resistance.
  6. Check for short to power or ground on the control circuit (with harness disconnected) using an ohmmeter. Repair any shorts.
  7. Disconnect the relay and test coil resistance against manufacturer specification. Replace relay if out of range or intermittent.
  8. Test clutch pedal switch for correct operation and continuity when pedal is depressed/released. Replace or adjust switch if faulty.
  9. If wiring and components test good, check the control module driver output. If suspect, consult advanced diagnostics/technical service information before replacing module.
  10. After repairs, clear codes and perform functional test/road test to verify fault does not return.

Likely causes

  • Damaged or disconnected wiring/connector between module and clutch pedal switch override relay
  • Defective override relay
  • Failed clutch pedal switch or its connector

Fault status

⚠️ Status
Open or short detected in clutch pedal switch override relay control circuit.

  • Faulty engine/control module driver output

Symptoms

  • Malfunction Indicator Lamp (MIL) or ECU warning lamp illuminated
  • Cruise control or clutch-interlock functions disabled
  • Starter interlock may not permit engine start (on some models)
  • Intermittent or no response from clutch pedal switch input

What to check

  • Scan for current and stored codes and view freeze-frame data
  • Visually inspect relay, connectors, and wiring for damage or corrosion
  • Check related fuses and grounds for continuity and tightness
  • Backprobe relay control circuit and observe voltage/continuity with clutch pedal operated
  • Swap relay with a known-good identical relay (if available) to test behavior
  • Check for intermittent faults by wiggling harness while monitoring signal

Signal parameters

  • Relay coil activation voltage: ~12 V (key on) when commanded by control module
  • De-energized: 0–0.5 V at control side for low/ground depending on design
  • Resistance of relay coil (typical): a few ohms to ~100 ohms (manufacturer spec required)
  • Expected continuity: control module pin to relay coil pin < 5 ohms (when connector present); open = infinite
  • No short to battery positive or ground when relay not energized (infinite/very high resistance)

Diagnostic algorithm

  1. Read and record DTCs and freeze-frame data with a scan tool. Note operating conditions when code set.
  2. Visually inspect relay, clutch pedal switch, connectors and wiring harness for damage, corrosion or loose pins.
  3. Check related fuses and chassis/engine grounds; repair any faults.
  4. With key ON (engine OFF), backprobe the relay control wire at the relay connector. Observe voltage while commanding the circuit with a scan tool (if possible) and while operating the clutch pedal. Compare to expected signal parameters.
  5. Measure continuity between the control module output pin and the relay control pin. Repair any opens or high resistance.
  6. Check for short to power or ground on the control circuit (with harness disconnected) using an ohmmeter. Repair any shorts.
  7. Disconnect the relay and test coil resistance against manufacturer specification. Replace relay if out of range or intermittent.
  8. Test clutch pedal switch for correct operation and continuity when pedal is depressed/released. Replace or adjust switch if faulty.
  9. If wiring and components test good, check the control module driver output. If suspect, consult advanced diagnostics/technical service information before replacing module.
  10. After repairs, clear codes and perform functional test/road test to verify fault does not return.
