Code 165 - Adjuster Assembly Motor Circuit Shorted To Ground (With TCS): Notes

Identifies TCS adjuster assembly motor that is shorted to ground. Malfunction will not allow adjuster assembly motor to be controlled at commanded current rate or will cause driver circuit to allow current directly to ground.

Code 165 can be set anytime. A malfunction exists if EBTCM detects an out of range voltage on either of the adjuster assembly circuits indicating a circuit shorted to ground. Code will be stored, TCS and BRAKE warning lights are illuminated.

NOTE: Test numbers refer to numbers on diagnostic chart. Use only 10-megohm (minimum) DVOM for all voltage and resistance tests. For identification of circuits and terminals referenced in charts and text, see WIRING DIAGRAMS .

Checks for short to ground in adjuster assembly motor high circuit.
Checks for short to ground in adjuster assembly motor low circuit.
Checks for adjuster assembly motor that is internally shorted to ground.
Ensures malfunction was not due to physical damage of circuit.
