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.

ESP

® Warning Lamp Comes ON Steady

S5JB0B4604056

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.

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
