ESP® Warning Light Comes ON Steady
Wiring Diagram
Refer to "ESP® Warning Light Does Not Come ON at Ignition Switch ON".
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.
Troubleshooting
Step
1 1) Perform diagnostic trouble code check.
Is there any DTC(s)?
2 Are main fuses for pump motor and solenoid valves in good
condition?
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?
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?
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
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?
