C0181











Circuit Description
Identifies an adjuster assembly motor circuit that is shorted to ground, shorted to voltage, or an open circuit. This malfunction will not allow the adjuster assembly motor to be controlled at the commanded current rate or will cause the driver circuit to allow current directly to ground.

Conditions for Setting the DTC
DTC C0181 can set anytime the ignition switch is in the RUN position and the EBCM detects an open, short to ground, or a short to voltage.

Action Taken When the DTC Sets
^ A malfunction DTC stores
^ The TCS disables
^ The amber TCS indicator turns on

Conditions for Clearing the DTC
^ The condition responsible for setting the DTC no longer exists and the scan tool Clear DTCs function is used.
^ 100 ignition cycles pass with no DTCs detected.

Diagnostic Aids
Thoroughly inspect any circuitry that may be causing the complaint for the following conditions:
- Backed out terminals
- Improper mating
- Broken locks
- Improperly formed or damaged terminals
- Poor terminal-to-wiring connections
- Physical damage to the wiring harness
The following conditions may cause an intermittent malfunction:
- A poor connection
- Rubbed-through wire insulation
- A broken wire inside the insulation
If an intermittent malfunction exists refer to Testing for Intermittent and Poor Connections.
