Test D: DTC C1266 Anti-lock Brake System (ABS) Valve Power Relay Circuit Failure

Refer to Vehicle/Diagrams, Vehicle Dynamic Systems for schematic and connector information.

Normal Operation
The operating voltage required to supply the anti-lock brake system (ABS) module isolation valves is in a range between 10 and 16 volts.

Fused battery voltage for the isolation valves is supplied by battery junction box (BJB) fuse 12 (20A) along circuit 685 (BK/WH). Ground is provided along circuit 1203 (BK/LB).

Possible Causes
^ Fuse
^ Circuit open
^ ABS module

CAUTION: Use the Flex Probe Kit for all test connections to prevent damage to the wiring terminals. Do not use standard multi-meter probes.
