4F-19 Electronic Stability Program: 

ESP

® Warning Light Does Not Come ON at Ignition Switch ON

S6JB0B4604008

Wiring Diagram

Circuit Description
Operation (ON/OFF) of ESP

® warning light is controlled by ESP® control module through light driver module in 

combination meter.
If ESP

® system is in good condition, ESP® control module turns ESP® 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, ESP

® warning light is 

turned ON continuously by ESP

® control module. Also, it is turned ON continuously by light driver module when the 

connector of ESP

® control module is disconnected.

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.
