PROBLEM VERIFICATION 

Disconnect the connector from the ABS control module and turn the ignition switch ON. 

Does the ABS warning lamp light up? 

YES  



It is normal. Recheck the ABS control module.  

NO  



Check the power source for the ABS warning lamp.  

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.



Inoperative ABS warning lamp bulb  



Blown No.2 fuse (10A) in the engine 
compartment junction block  



Inoperative ABS warning lamp module

Specification: approximately B+ 

Is voltage within specification? 

YES  



Repair bulb or instrument cluster assembly.  

NO  



Check for blown fuse.

CHECK FOR BLOWN FUSE 

Check continuity of fuse (10A) from the engine compartment junction block. 

Is there continuity? 

YES  



Repair an open in the wire between ABS fuse and 1 of cluster connector.

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.

Is there continuity? 

YES  



Replace the ABS control module and recheck.  

NO  



Repair an open in the wire between cluster and ABS control module.  

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
