DTC C1281 (2 Of 2):

CIRCUIT DESCRIPTION
This DTC identifies a brake solenoid valve that cannot be energized due to a short to voltage in its driver circuitry. This malfunction can affect ABS operation since the flow of brake fluid to the wheel cylinder cannot be stopped, making ABS operation for that channel impossible.

CONDITIONS FOR SETTING THE DTC
DTC C1281 can be set only when the solenoid is commanded on. If the EBCM detects the right front brake solenoid valve control circuit voltage is out of specification, a malfunction exists.

ACTION TAKEN WHEN THE DTC SETS
A malfunction DTC is stored, ABS is disabled. The amber ABS warning indicator is turned on.

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. The frequency of the malfunction can be checked by using the enhanced diagnostic function of the scan tool. 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.

NOTE: J 39200 test leads must be zeroed prior to making any resistance measurements. Refer to J 39200 user's manual.
