CIRCUIT DESCRIPTION
DTC No.DTC Detecting ConditionTrouble Area
51
In the midst of initial check, after the current flows to the
motor for 3 sec. and motor relay is turned OFF , then
within 0.66 sec., the condition that the motor relay
monitor is OFF continues for 0.24 sec. or more.

ABS pump motor
Fail safe function:
If any trouble occurs in the ABS & TRAC pump motor, the ECU cuts off current to the ABS & TRAC solenoid
relay and prohibits ABS control and TRAC control.

ABS Warning Light Circuit
CIRCUIT DESCRIPTION
If the ECU detects a 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.
Connect terminals Tc and E
1 of the DLC1 or DLC2 to make the ABS warning light blink and output the DTC.

INSPECTION PROCEDURE
Troubleshoot in accordance with the chart below for each trouble symptom.

ABS warning light remains onGo to step 3
1 Check ABS warning light.

CIRCUIT DESCRIPTION
The sensor check circuit detects abnormalities in the speed sensor signal which cannot be detected with
the DTC check.
Connecting terminals Ts and E
1 of the DLC1 in the engine compartment starts the check.

INSPECTION PROCEDURE
1 Check voltage between terminals Ts and E1 of DLC1.
CHECK:
(a) Turn the ignition switch ON.
(b) Measure voltage between terminals Ts and E
1 of DLC1.
OK:
Voltage: 10 ± 14 V
OK If ABS warning light does not blink even after Ts
and E
1 are connected, the ECU may be defec-
tive.
