Circuit Description
Operation (ON/OFF) of ABS warning lamp is controlled by ABS control module through lamp driver module in
combination meter.
If the Antilock brake system is in good condition, ABS control module turns ABS warning lamp ON at the ignition
switch ON, keeps it ON for 2 seconds and then turns it OFF. If an abnormality in the system is detected, ABS warning
lamp is turned ON continuously by ABS control module. Also, it is turned ON continuously by lamp driver module when
the connector of ABS control module is disconnected.
Troubleshooting
Step Action Yes No
1 1) Perform diagnostic trouble code check.
Is there any DTC(s)?
Go to Step 7 of “ABS
Check”. Go to Step 2.
2 Is “ABS” fuses (60 A and 10 A) in good condition? Go to Step 3. Replace fuse and check
circuit for short to
ground.
3 1) Turn ignition switch to OFF.
2) Disconnect ABS hydraulic unit / control module
connector.
3) Check for proper connection to ABS hydraulic unit /
control module connector at terminals “E15-7”, “E15-17”
and “E15-13”.
4) If OK then turn ignition switch to ON position and
measure voltage between terminal “E15-7” and vehicle
body ground.
Is it 10 – 14 V?
Go to Step 4. “GRN/ORN” circuit
open.
4 1) Turn ignition switch to OFF position.
2) Check for proper connection to ABS hydraulic unit /
control module connector at terminals “E15-1” and “E15-
14”.
3) If OK then turn ignition switch to ON position and
measure voltage between each terminal of “E15-1”,
“E15-14” and vehicle body ground.
Are they 10 – 14 V?
Go to Step 5. “WHT/BLU” circuit
open.
5 1) Turn ignition switch to ON and light the ABS warning
lamp.
2) Connect terminal “E15-17” of disconnected connector to
vehicle body ground using service wire.
Does ABS warning lamp turn off?
Go to Step 6. “RED/WHT” circuit
open. If wire and
connection are OK,
replace combination
meter.
6 1) Turn ignition switch to OFF and measure resistance
between each terminal of “E15-13”, “E15-26” and vehicle
body ground.
Is resistance less than 2
Ω
?
Substitute a known-
good ABS hydraulic
unite / control module
assembly and recheck. “BLK” wire circuit in
open or high resistance.
