Causes
- Solenoid coil internally shorted (low resistance or short to coil casing)
- Damaged wiring harness (chafing, pinched, exposed conductor) causing short to ground or battery
- Corroded or water-intruded connector causing low-resistance path
- Shorted connector pins (solder splashes, bent pins) or poor terminal seating
- Failed control module/driver transistor that is shorted
- Blown/weak fuse or damaged relay related to the solenoid circuit
Symptoms
- Malfunction indicator lamp or specific system warning (ABS/TC, AT, 4WD, etc.)
- Associated system in limp or reduced functionality mode (e.g., no engage, abnormal shifting, loss of ABS)
- Immediate or repeated tripping of related fuse
- Burnt smell or visible heat/melt at wiring/connector in severe shorts
- Stored DTC(s) and inability to activate the solenoid from a diagnostic tool
What to check
- Retrieve all stored/related DTCs and freeze frame/live data with a capable scan tool
- Visually inspect solenoid, connector, and wiring for heat damage, corrosion, or pin damage
- Check fuses and relays for the circuit; replace if blown and monitor if it blows again
- Measure solenoid coil resistance and compare with service specification
- Backprobe the connector and confirm supply and driver voltages with activation command
- Perform a wiggle test on harness while monitoring current or voltage to reproduce fault
Signal parameters
- Supply voltage: nominal battery voltage ~12 V (engine off) or ~13.5–14.5 V (engine running); short to battery = stuck at ~12 V
- Driver output: normally switched (ground or switched +) or PWM; expected switching between ~0 V and battery voltage when activated
- Coil resistance: varies by application — typically in the range of 20–200 ohms; consult service manual. Very low (1 kΩ or OL) indicates open circuit
- Activation current: depends on coil resistance and supply voltage; unusually high current indicates shorted coil or short to ground
- PWM frequency/duty: if used, typically hundreds of Hz; check service data for exact values
Diagnostic algorithm
- Read fault codes, note freeze-frame and associated subsystem warnings. Check for related codes that narrow the subsystem (ABS, AT, 4WD, etc.).
- Perform a visual inspection of the solenoid, connector, and nearby harness. Look for melted insulation, corrosion, dirt/water ingress, or rodent damage.
- With ignition OFF, disconnect the solenoid connector and measure coil resistance across the solenoid terminals; compare to spec. If resistance indicates a short, replace the solenoid.
- Inspect connector pins for corrosion, continuity between pin and shell, and for short to ground/power using an ohmmeter. Repair or replace the connector as needed.
- With connector disconnected, check for short to battery or ground in the harness: measure resistance from the solenoid connector pin to vehicle ground and to battery positive. Low resistance indicates a short in the wiring.
- If harness checks good, reconnect and use a scan tool to command the solenoid while monitoring the module output voltage/current. If the module output is stuck or reads abnormal values, suspect control module driver failure.
- Perform a wiggle/stress test on the harness while commanding the solenoid to try to reproduce the fault; isolate the location of intermittent shorts.
- If needed, substitute a known-good solenoid or temporarily power the solenoid from a fused bench supply through an inline ammeter to confirm solenoid behavior (observe safe current limits).
- Repair wiring (splice, replace section, or replace connector) or replace solenoid as indicated. If module driver is suspected after isolating wiring and solenoid, refer to service procedures for ECU/ABS module repair or replacement.
- Clear codes and road/test as required. If the fault returns, re-check wiring and module outputs; escalate to module repair or replacement if wiring and solenoid are confirmed good.
Likely causes
- Wiring short to ground at a harness chafe point near the solenoid
- Corroded connector allowing current bypass (especially in wet areas)
- Solenoid coil failure (internal short)
- Faulty module output transistor/driver inside ECU
- Blown fuse or shorted relay upstream of the solenoid
Fault status
Status
C1413 — Solenoid circuit short detected. The control module reports excessive current/low resistance on the solenoid driver circuit. Inspect solenoid, harness, connector, fuses and module driver.
Repair difficulty: Medium
Diagnostic time: 1-3 hours
