ESP

® Warning Lamp Does Not Come ON at Ignition Switch ON

S5JB0B4604055

Wiring Diagram

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.
