Are they in good condition?

Go to Step 3.

Repair or replace.

3

Check back up light switch circuit
1) Turn ignition switch to OFF position.
2) Disconnect ESP

® control module connector.

3) Check for proper connection to ESP

® control module 

connector terminal at “E53-10”.

4) If OK, then measure voltage between connector terminal 

“G53-10” and vehicle body ground.

Is it 0 V?

Go to Step 4.

“RED” wire circuit 
shorted to power circuit.

4

Check back up light switch circuit
1) Turn ignition switch to ON position.
2) Measure voltage between connector terminal “G53-10” 

and vehicle body ground with the shift lever in “Reverse” 
position.

Is it 10 – 14 V?

Substitute a known-
good ESP

® hydraulic

1

Was “Electronic Stability Program Check” performed?

Go to Step 2.

Go to “Electronic 
Stability Program 
Check”.

2

DTC check
1) Connect scan tool to DLC with ignition switch turned 

OFF.

2) Turn ignition switch ON and check DTC.

Is DTC C1057 detected?

Go to “DTC C1057: 
ABS (EPS

®) Control 

Module Power Supply 
Circuit Failure in Section 
4E”.

Go to Step 3.

3

Check each control module connectors
1) Check connection of connectors of all control modules 

communicating by means of CAN (for yaw rate / G 
sensor assembly).

2) Check DTC for ESP

®.

Is DTC C1073 detected?

Go to Step 4.

Check for intermittent 
trouble. Check for 
intermittent referring to 
“Intermittent and Poor 
Connection Inspection 
in Section 00 in related 
manual”.

4

CAN communication circuit check
1) Turn ignition switch to OFF position.
2) Disconnect connectors of ESP

® control module and yaw 

rate / G sensor assembly.

Is each CAN communication circuit between ESP

®

 control 

module and yaw rate / G sensor assembly opened, shorted 
or high resistance?

Repair or replace the 
CAN communication 
line.

Go to Step 5.
