4F-22 Electronic Stability Program: 

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.

Inspection

6

1) Check CAN communication circuit between combination 

meter and ESP

® 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 lamp remains 
ON, substitute a known-
good ESP
