Wiring Diagram
Refer to “Warning Diagram” under “ABS Warning Light Does Not Come ON at Ignition Switch ON”.
Circuit Description
Refer to “Circuit Description” under “ABS Warning Light Does Not Come ON at Ignition Switch ON”.
Troubleshooting 3Combination meter power source circuit check
1) Remove combination meter with ignition switch turned
OFF.
2) Check for proper connection to “RED/BLK” and “BLK”
wire of combination meter connector.
3) If OK then turn ON ignition switch and measure voltage
at “RED/BLK” wire of combination meter connector and
vehicle body ground.
Is it 10 - 14 V?Go to Step 4. Repair power source
circuit for combination
meter.
4Combination meter ground circuit check
1) Measure resistance between “BLK” wire of combination
meter connector and vehicle body ground.
Is resistance less than 2
Ω?Substitute a known-
good combination meter

EBD Warning Light (Brake Warning Light) Comes ON SteadyS6RW0D4504010
Wiring Diagram
Referring to “Wiring Diagram” under “ABS Warning Light Does Not Come ON at Ignition Switch ON”.
Circuit Description
EBD warning lamp (brake warning lamp) is controlled by ABS control module and BCM through lamp driver module in
combination meter.
If EBD system is in good condition, ABS control module turns EBD warning lamp ON at the ignition switch ON, keeps
it ON for 2 seconds and then turns it OFF.
EBD warning lamp is turned ON continuously at the following conditions.
• EBD system is an abnormality
• Connector of ABS control module is disconnected
• Parking brake switch is ON
• Brake fluid level is lower than minimum level
The information of parking brake switch and brake fluid level are transmitted from BCM to lamp driver module in
combination meter through CAN communication line.
Troubleshooting
Step Action Yes No

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.
2ABS warning light operation check
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.
3Parking brake switch circuit and brake fluid level switch
circuit check
1) Release parking brake completely, and replenish brake
fluid.
2) Disconnect BCM connectors with ignition switch turned
OFF.
3) Measure resistance between each parking brake switch
circuit, brake fluid level switch circuit and vehicle body
ground.
Are resistance
∞Ω?Go to Step 4. Check each applicable
circuit for short to
vehicle body ground. If
OK then check parking
brake switch and/or
brake fluid level switch.
4DTC check of BCM
1) Connect scan tool to data link connector with ignition
switch turned OFF.
2) Turn ignition switch to ON position and check DTC of
BCM.
Is there DTC U0073?Go to “DTC U0073 (No.
0073): Control Module
Communication Bus Off
in Section 10B”.Go to Step 5.
