ABS Warning Light Does Not Come ON at Ignition Switch ONS7RS0B4504008
Wiring Diagram
Circuit Description
Operation (ON/OFF) of ABS warning light is controlled by ABS contro l module through lamp driver module in
combination meter.
If the antilock brake system is in good condition, ABS control module turns ABS warning light 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 light is
turned ON continuously by ABS control module. Also, it is turned ON continuously by la mp driver module when the
connector of ABS control module is disconnected.

1 1) Turn ignition switch to ON position.
Do other warning lights come ON? Go to Step 2.
Go to Step 3.
2 1) Connect scan tool to DLC with ignition switch turned OFF.
2) Turn ignition switch to ON position and check DTC.
Is there DTC U1073? Go to “DTC U1073:
Control Module

Off”.
Substitute a known-
good combination meter
and recheck. If ABS
warning light remains
OFF, substitute a
known-good ABS
hydraulic unit / control
module assembly and
recheck.
3 Is Circuit fuse fo r combination meter in good condition? Go to Step 4.Replace fuse and check
for short circuit to

ABS Warning Light Comes ON SteadyS7RS0B4504009
Wiring Diagram
Refer to “ABS Warning Light Does Not Come ON at Ignition Switch ON”.
Circuit Description
Operation (ON/OFF) of ABS wa rning light is controlled by ABS contro l module through lamp driver module in
combination meter.
If the Antilock brake system is in good condition, ABS control module turns ABS warning lig ht 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 light is
turned ON continuously by ABS c ontrol module. Also, it is turned ON continuously by la mp driver module when the
connector of ABS control module is disconnected.
Troubleshooting 4 Check CAN communication circuit between combination
meter and ABS control module referring to “DTC U1073:
Control Module Communication Bus Off”.
Is CAN communication circuit in good condition? Go to Step 5.
Repair or replace.
5 1) Remove combination meter wit h ignition switch turned
OFF.
2) Check for proper connection to “RED/BLK” and “BLK/ ORN” wire of combinat ion meter connector.
3) If OK, turn ON ignition switch and measure voltage at “PPL/RED” wire of combi nation meter connector and
vehicle body ground.
Is it 10 – 14 V? Go to Step 6.
Repair power supply
circuit for combination
meter.
6 1) Measure resistance between “BLK/ORN” wire of combination meter connector and vehicle body ground.
Is resistance less than 2
Ω? Replace combination
meter.
“BLK/ORN” circuit open
or high resistance.
Step Action Yes No
Step
Action YesNo
1 1) Perform diagnostic trouble code check.
Is there any DTC(s)? Go to applicable DTC
diag. flow.
Go to Step 2.
2 Are main fuses for ABS pump motor and ABS solenoid 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 control module connector.
3) Check for proper connection to ABS control module connector at terminals “E03-7”, “E03-13” and “E03-26”.
4) If OK then turn ignition switch to ON position and measure voltage between terminal “E03-7” 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 control module connector at terminals “E03-1” and “E03-14”.
3) If OK then turn ignition switch to ON position and measure voltage between each terminal of “E03-1”,
“E03-14” and vehicle body ground.
Are they 10 – 14 V? Go to Step 5.
“WHT/RED” and/or
“WHT/BLU” circuit

EBD Warning Light (Brake Warning Light) Comes ON SteadyS7RS0B4504010
Wiring Diagram
Refer to “ABS Warning Light Does Not Come ON at Ignition Switch ON”.
Circuit Description
EBD warning light (brake warn ing light) is controlled by parking brake switch, brake fluid level switch and ABS
hydraulic unit / control module assembly throug h lamp driver module in combination meter.
EBD warning light turns ON when parki ng brake switch is ON and/or brake fluid level is lower than minimum level.
The information of parking brake switch and brake fluid leve l are transmitted from BCM to lamp driver module in
combination meter through CAN communication line.
Troubleshooting 5 1) Turn ignition switch to OFF and measure resistance
between each terminal of “E03-13”, “E03-26” and vehicle
body ground.
Is resistance less than 2
Ω? Go to Step 6. Ground circuit for ABS
hydraulic unit / control
module open or high
resistance.
6 Check CAN communication circuit between combination meter and ABS control module referring to “DTC U1073:
Control Module Communication Bus Off”.
Is CAN communication circuit in good condition? Substitute a known-
good combination meter
and recheck. If ABS
warning light remains
ON, substitute a known-
good ABS hydraulic unit
/ control module
assembly and recheck.Repair or replace.
Step Action Yes No
Step
Action YesNo
1 1) Make sure that:
• Parking brake is completely released.
• Brake fluid level is upper than the minimum level.
Are the check results OK? Go to Step 2.
Release parking brake
completely and/or
replenish brake fluid.
2 1) Turn ignition switch to ON position. Does “ABS” warning light come on steady? Perform “ABS Warning
Light Comes ON
Steady” previously
outlined.Go to Step 3.
3 1) CAN communication circuit between combination meter, ABS hydraulic unit / control module and BCM referring to
“DTC U1073: Control Module Communication Bus Off”.
Is CAN communication circuit in good condition? Substitute a known-
good combination meter
and recheck. If ABS
warning light remains
ON, substitute a known-
good ABS hydraulic unit
/ control module
assembly and recheck.Repair or replace.
