DTC 51 ABS Pump Motor Lock
CIRCUIT DESCRIPTION
DTC No.DTC Detecting ConditionTrouble Area
51Pump motor is not operating normally during initial check
ABS pump motor
Fail safe function:
If trouble occurs in the ABS pump motor, the ECU cuts off the current to the ABS control (solenoid) relay and
prohibits ABS control.

ABS Warning Light Circuit
CIRCUIT DESCRIPTION
If the ECU detects trouble, it lights the ABS warning light while at the same time prohibiting ABS control. At
this time, the ECU records a DTC in memory.
After removing the short pin of the DLC1, connect between terminals Tc and E
1 of the DLC1 to make the
ABS warning light blink and output the DTC.
