DTC C1294 (2 Of 2):

CIRCUIT DESCRIPTION
This DTC determines the proper operation of the stoplamp switch. This is important because ABS is activated when the brake switch is on and ABS is deactivated when the stoplamp switch is off. If the brake switch is always on, ABS operation will always be requested.

CONDITIONS FOR SETTING THE DTC
DTC C1294 can be set when the vehicle reaches at least 40 km/h (25 mph). If the brake was always on during two consecutive drive cycles, a malfunction exists.

ACTION TAKEN WHEN THE DTC SETS
A malfunction DTC is stored. ABS operation remains.

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.
