Code Description
ABS Hydraulic Pump Motor Circuit Failure/Open
Anti-lock brake system (ABS) diagnostic trouble code (DTC) C1095 sets only when the motor is initially commanded on for 100 ms (+1-6 ms), and the ABS hydraulic pump motor is then commanded off and the voltage back is read after 6 ms. If the voltage indicates the motor is spinning at less than 500 RPM, there may be a locked motor. If this condition is detected 4 times, a locked motor DTC C1095 is set. The pump motor is checked for an open circuit 2 seconds after the most recent successful pump motor off command. If the pump motor feedback remains greater than 0.75 volt for more than 50 ms (+1-6 ms) after these conditions have been met, DTC C1096 is set.
Voltage is supplied from the battery junction box (BJB) through circuit 532 (OG/YE) (voltage at all times). Ground is provided through circuit 530 (LG/YE).
