Pinpoint Test D: DTC C1095 And C1095- ABS Hydraulic Pump Motor Circuit Failure/Open

Test D1 - D4 Continued:




Tests D4 - D5:





Normal Operation
ABS DTC C1095 only sets when the motor is initially commanded on for 100 msec (+6 ms, -6 msec), and the ABS hydraulic pump motor is then commanded off and the voltage back is read after 6 msec. If the voltage indicates that 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 V for more than 50 msec (+6 ms, -6 ms) after these conditions have been met, then a DTC C1096 is set.

Voltage is supplied by circuit 534 (YE/LG) (power hot at all times). Ground is provided through circuit 1205 (BK). Possible Causes
^ circuit 1205 (BK) open
^ circuit 534 (YE/LG) open
^ hydraulic pump motor
^ ABS module
