DTC C1363: Right TCS Motor Circuit Shorted To Voltage:

DTC C1363 Continued:

Schematic:

Circuit Description
This DTC identifies a TCS motor circuit that is shorted to voltage or a TCS motor that has low or no resistance. This malfunction will not allow the TCS motor to be controlled at the commanded current rate or will cause the TCS motor to turn in the opposite direction, or not at all.


Conditions for Setting the DTC
DTC C1363 can be set only when the TCS motor is commanded off. If the Electronic Brake Traction Control Module (EBTCM) detects an out of range voltage on either of the right front TCS motor circuits indicating a circuit shorted to voltage or a TCS motor shorted, a malfunction exists.


Action Taken When the DTC Sets
A malfunction DTC is stored, Traction Control System (TCS) is disabled and the amber TCS warning indicator is turned on.

Conditions for Clearing DTC
Condition for DTC is no longer present and the scan tool (CLEAR DTCs) function is used, or 100 drive cycles have passed with no DTCs detected.


Diagnostic Aids
An intermittent malfunction may be caused by a poor connection, rubbed-through wire insulation, or a wire that is broken inside the insulation.

If the malfunction is not current, wiggle the wires of the affected channel and check if the DTC resets. This will help to pinpoint an intermittent malfunction in the motor circuitry or connections.

The frequency of the malfunction can be checked by using the enhanced diagnostic function of the scan tool, as described in the Scan Tool manual.

Any circuitry that is suspected of causing the intermittent complaint should be thoroughly checked for backed out terminals, improper mating, broken locks, improperly formed or damaged terminals, poor terminal to wiring connections or physical damage to the wiring harness.
