Test C: DTCs C1095 and C1096 - ABS Hydraulic Pump Motor Circuit Failure/Open
Pinpoint Test C: DTCs C1095 and C1096 ABS Hydraulic Pump Motor Circuit Failure/OpenNormal Operation
Anti-lock brake system (ABS) diagnostic trouble code (DTC) C1095 sets only when the motor is initially commanded on for 100 ms (±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, then 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 (±6 ms) after these conditions have been met, then DTC C1096 is set.
Fused battery voltage is supplied from the bussed electrical center (BEC) through circuit 534 (YE/LG). Ground is provided through circuit 1205 (BK).
