DESCRIPTION
The ABS motor relay supplies power to the ABS pump motor. While the ABS is activated, the ECU turns the motor relay on and operates the ABS pump motor.
If the voltage supplied to the motor relay (+BM) is below the DTCs detection threshold due to low voltage from the battery/alternator, the DTCs may be stored.

INSPECTION PROCEDURE
HINT: After steps 1, 2 and 3 are completed, start the inspection from step 4 when using the intelligent tester, and from step 5 when not using the intelligent tester.
1 INSPECT FUSE (ABS 1 FUSE)
(a) Remove the ABS 1 fuse from the FL block.
(b) Measure the resistance according to the value(s) in the table below.
Standard resistance
2 INSPECT SKID CONTROL ECU (+BM TERMINAL VOLTAGE)
(a) Install the ABS 1 fuse.
(b) Disconnect the skid control ECU connector.
(c) Measure the voltage according to the value(s) in the table below.
Standard voltage
3 INSPECT SKID CONTROL ECU (GND TERMINAL CONTINUITY)
(a) Measure the resistance according to the value(s) in the table below.
Standard resistance
4 PERFORM ACTIVE TEST BY INTELLIGENT TESTER (ABS MOTOR RELAY)
(a) Reconnect the skid control ECU connector.
(b) Connect the intelligent tester to the DLC3.
(c) Turn the ignition switch to the ON position and turn the intelligent tester main switch on.
(d) Start the engine.
(e) Select the ACTIVE TEST mode on the intelligent tester.
ABS:
(f) Check operating sound of the ABS motor when operating it with the intelligent tester.
OK: The operating sound of the ABS motor is heard.
5 RECONFIRM DTC
(a) Clear the DTCs (See page BC-10).
(b) Start the engine.
(c) Drive the vehicle at the speed of 6 km/h (4 mph) or more.
(d) Check that the same DTCs are recorded (See page BC- 10).

SRS Warning Light Remains ON
DESCRIPTION
The SRS warning light is located on the combination meter assembly.
When the SRS is normal, the SRS warning light comes on for approximately 6
seconds after the ignition
switch is turned from the LOCK position to ON position, and then goes off
automatically.
If there is a mal ...
