ABS - With Traction Control

CIRCUIT DESCRIPTION
This DTC is used to identify open brake switch circuitry that prevents the brake switch input to the EBCM/EBTCM from changing states when the brake is applied. This DTC is used in conjunction with DTCs C1291 and C1292 to determine the cause of an open brake switch malfunction.

CONDITIONS FOR SETTING THE DTC
DTC C1295 can be set after initialization is completed. If the brake switch input voltage is out of specification for one second, indicating an open circuit, a malfunction exists.

ACTION TAKEN WHEN THE DTC SETS
A malfunction DTC is stored, ABS/ETS is disabled, and the amber ABS 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 DTC(s) 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. An intermittent malfunction may be caused by a sticking stoplamp switch. The stoplamp switch should be checked for this condition and adjusted or replaced as necessary. 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.
