ESP
®
Warning Lamp Comes ON Steady
S5JB0E4604009
Wiring Diagram
Refer to “ESP
®
Warning Lamp Does Not Come ON at Ignition Switch ON: ”.
Circuit Description
Operation (ON/OFF) of ESP
®
warning lamp is controlled by ESP
®
control module through lamp driver module in
combination meter.
If ESP
®
system is in good condition, ESP
®
control module turns ESP
®
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, ESP
®
warning lamp is
turned ON continuously by ESP
®
control module. Also, it is turned ON continuously by lamp driver module when the
connector of ESP
®
control module is disconnected.
Troubleshooting
5 1) Remove combination meter with ignition switch turned
OFF.
2) Check for proper connection to “PPL/RED” and “BLK”
wire of combination meter connector.
3) If OK, turn ON ignition switch and measure voltage at
“PPL/RED” wire of combination 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” wire of combination
meter connector and vehicle body ground.
Is resistance less than 2
Ω
?
Replace combination
meter. “BLK” circuit open or
high resistance.
Step Action Yes No
Step Action Yes No
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 ESP
®
control module connector.
3) Check for proper connection to ESP
®
control module
connector at terminals “E53-35”, “E53-16” and “E53-47”.
4) If OK then turn ignition switch to ON position and
measure voltage between terminal “E53-35” 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 ESP
®
control module
connector at terminals “E53-1” and “E53-32”.
3) If OK then turn ignition switch to ON position and
measure voltage between each terminal of “E53-1”,
“E53-32” and vehicle body ground.
Are they 10 – 14 V?
Go to Step 5. “WHT/RED” and/or
“WHT/BLU” circuit
open.
5 1) Turn ignition switch to OFF and measure resistance
between each terminal of “E53-16”, “E53-47” and vehicle
body ground.
Is resistance less than 2
Ω
?
Go to Step 6. Ground circuit for ESP
®
control module open or
high resistance.
