CIRCUIT DESCRIPTION
DTC C1357 identifies a TCS motor circuit that shorts to ground. DTC C1357 will cause one of the following conditions:
^ The TCS motor cannot be controlled at the commanded current rate.
^ The TCS motor driver circuit will allow current to go directly to ground.

CONDITIONS FOR SETTING THE DTC
DTC C1357 can set anytime. A malfunction exists if the EBCM/EBTCM detects an out of range voltage on either of the left front TCS motor circuits, indicating a short to ground.

ACTION TAKEN WHEN THE DTC SETS
^ A malfunction Diagnostic Trouble Code (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 drive cycles pass with no DTC(s) detected.

DIAGNOSTIC AIDS
The following conditions may cause an intermittent malfunction:
^ A poor connection
^ Rubbed-through wire insulation
^ A broken wire inside the insulation

If the malfunction is not current, perform the following procedure in order to pinpoint identify an intermittent malfunction in the motor circuitry or connections:
1. Wiggle the wires of the affected channel.
2. Inspect to see if the DTC resets.

Use the enhanced diagnostic function of the Scan Tool in order to measure the frequency of the malfunction. Refer to the Scan Tool manual for the procedure.

Thoroughly inspect any circuitry that may cause the intermittent 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
