4F-20 Electronic Stability Program:

ESP

® Warning Light Does Not Come ON at Ignition Switch ON

S6JB0A4604010

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.

Troubleshooting

Step

Action

Yes

No

1

1) Turn ignition switch to ON position.

Do other warning lights come ON?

Go to Step 2.

Go to Step 3.

2

1) Connect scan tool to DLC with ignition switch turned

OFF.

2) Turn ignition switch to ON position and check DTC.

Is there DTC U1073?

Go to “DTC U1073:
Control Module
Communication Bus
Off” for troubleshooting.

Substitute a known-
good combination meter
and recheck. If ESP

®

warning light remains
OFF, substitute a
known-good ESP

®

hydraulic unit / control
module assembly and
recheck.

3

Is Circuit fuse for combination meter in good condition?

Go to Step 4.

Replace fuse and check
for short circuit to
ground.

4

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?

Go to Step 5.

Repair or replace.

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.

“BLK” circuit open or
high resistance.

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

Action

Yes

No

1

1) Perform diagnostic trouble code check.

Is there any DTC(s)?

Go to applicable DTC
diag. flow.

Go to Step 2.

2

Are main fuses for pump motor and solenoid valves in good
condition?

Go to Step 3.

Replace fuse and check
circuit for short to
ground.

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?

Go to Step 4.

“GRN/ORN” circuit
open.

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?

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
body ground.

Is resistance less than 2

Ω

?

Go to Step 6.

Ground circuit for ESP

®

control module open or
high resistance.

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 light remains
ON, substitute a known-
good ESP

® hydraulic

unit / control module
assembly and recheck.

Repair or replace.
