CIRCUIT DESCRIPTION
DTC C1294 determines the proper operation of the brake switch. Proper operation of the brake switch is important because ABS is activated and ETS is inhibited when the brake switch is on. The brake switch deactivates the ABS when the brake switch is off. The following conditions always occur when the brake switch is on:
- ABS operation is always requested.
- ETS operation is inhibited.

CONDITIONS FOR SETTING THE DTC
DTC C1294 can set if the vehicle's speed is greater than 40 km/h (25 mph).
A malfunction exists if the brake was always on during two consecutive drive cycles.

ACTION TAKEN WHEN THE DTC SETS
- A malfunction Diagnostic Trouble Code (DTC) stores.
- ABS operation remains.
- ETS operation is inhibited.

CONDITIONS FOR CLEARING THE DTC
- The condition responsible for setting the DTC no longer exists and the Scan Tool Clear DTCs function is used.
- 100 drive cycles pass with no DTCs detected.

DIAGNOSTIC AIDS
The following conditions may cause an intermittent malfunction:
- A poor connection
- Rubbed-through wire insulation
- A broken wire inside the insulation Use the enhanced diagnostic function of the Scan Tool in order to measure the frequency of the malfunction. Refer to the Scan Tool manual or Scan Tool Diagnosis for the procedure.

Thoroughly inspect any circuitry that may cause the intermittent complaint for the following conditions:
- Backed out terminals
- I improper mating
- Improperly formed or damaged terminals
- Poor terminal-to-wiring connections
- Physical damage to the wiring harness
