CHECK THE POWER SOURCE FOR THE ABS WARNING LAMP

Trouble Symptoms

Possible Cause

When current flows in the HECU the ABS warning
lamp turns from ON to OFF as the initial check.
Therefore if the lamp does not light up, the cause
may be an open in the lamp power supply circuit, a
blown bulb, an open in the both circuits between the
ABS warning lamp and the HECU, and the
inoperative HECU.

DETECTING CONDITION

DETECTING CONDITION CHART

INSPECTION PROCEDURES

CHECK DTC OUTPUT.

1. Connect the Scan Tool (pro) to the 16P data link connector located behind the driver's side kick panel.

2. Check the DTC output using Scan Tool (pro).

Is DTC output?

YES



Repair circuit indicated by code output.

NO



Check instrument cluster.

CHECK INSTRUMENT CLUSTER

Disconnect the cluster connector and turn the ignition switch ON.

Does the ABS warning lamp remains ON?

YES



Replace the instrument cluster.

NO



Check for open the wire.

CHECK FOR OPEN IN THE WIRE

Check for continuity in the wire between cluster and ABS control module.

Trouble Symptoms

Possible Cause

If the HECU detects trouble, it lights the ABS
warning lamp while at the same time prohibiting
ABS control. At this time, the HECU records a DTC
in memory. Even though the normal code is output,
the ABS warning lamp remains ON, then the cause
may be probably an open or short in the ABS
warning lamp circuit.

BLEEDING OF BRAKE SYSTEM

This procedure should be followed to ensure adequate bleeding of air and filling of the ABS unit, brake lines
and master cylinder with brake fluid.

1. Remove the reservoir cap and fill the brake reservoir with brake fluid.

2. Connect a clear plastic tube to the brake caliper bleeder plug and insert the other end of the tube into a

half filled clear plastic bottle.

3. Connect the scan tool to the data link connector located underneath the dash panel.

CAUTION: If there is any brake fluid on any painted surface, wash it off

immediately.

NOTE:

When pressure bleeding, do not depress the brake pedal.
Recommended fluid. ... DOT3 or DOT4
