Circuit Description

Battery voltage is supplied to the electronic brake
control module (EBCM) through fuse F3 and F2 in the
I/P fuse block, to terminal 15 and 20 of the EBCM
connector. The voltage is present when the ignition
switch is in ON or START.

Diagnosis

This test checks for battery output, proper grounding,
blown fuses, a faulty ignition switch, and problems in
the circuitry.

Cause

•

The battery is defective.

•

There is a defective ground connection.

•

A wire is broken or shorted.

•

A fuse is blown.

•

The ignition switch is malfunctioning.

Action Taken When the DTC Sets

ABS action is disabled during the period of low voltage,
and the ABS warning lamp is ON for the remainder of
the ignition cycle.

Test Description

The number(s) below refer to step(s) on the diagnostic
table.

1. This step determines whether there is voltage at

the battery and the high current source.

7. This step checks for voltage at the ignition 1

source.

Diagnostic Aids

It is very important to perform a thorough inspection
of the wiring and the connectors. Failure to do so may
result in misdiagnosis, causing part replacement with
a reappearance of the malfunction.

2. Remove fuse F2.

3. Disconnect the ABS connector from the EBCM.
4. Measure the resistance between ground and

terminal 20.

Is the resistance equal to the specified value?
Repair the short to ground in circuit fuse F2 of the I/P
fuse block and terminal 20 of the ABS harness EBCM
connector.

Is the repair complete?

1. Disconnect the EBCM connector from the EBCM.
2. Turn the ignition to ON.

3. Check for the presence of battery voltage between

ground and terminal 17, 18.

Is the voltage equal to the specified value?
