PINPOINT TEST 2: DTC C1095 - ANTI-LOCK BRAKE SYSTEM (ABS) HYDRAULIC PUMP MOTOR CIRCUIT FAILURE

Normal Operation

When the ignition key is turned to the RUN position, the ABS module will command the pump motor to run for approximately 2 seconds. During an ABS event, the ABS module will command the pump motor to run until the ABS event is over.Fused battery voltage for the hydraulic pump motor is supplied to the ABS module from battery junction box (BJB) fuse 9 (50A) along circuit (R) and ground is provided along (B/G).

- DTC C1095 (Anti-Lock Brake System (ABS) Hydraulic Pump Motor Circuit Failure) - When the ignition key is turned to the RUN position or anytime during a pump motor circuit check or ABS event, if the ABS module detects a short circuit to ignition or ground, an open circuit, a non-rotating pump or a defective internal power transistor, DTC C1095 will set.
