1

Was “Electronic Stability Program Check” performed?

Go to Step 2

Go to “Electronic 
Stability Program 
Check”
.

2

Check steering angle sensor power supply circuit
1) Check circuit fuses for steering angle sensor and its 

circuit.

Is it good condition?

Go to Step 3.

Replace fuse and check 
for short circuit to 
ground.

3

Check steering angle sensor power supply circuit
1) Turn ignition switch to OFF position.
2) Disconnect steering angle sensor connector.
3) Check for proper connection to steering angle sensor 

connector terminals at “E45-1”, “E45-2” and “E45-3”.

4) If OK, then measure voltage between connector terminal 

“E45-3” and vehicle body ground.

Is it 10 – 14V?

Go to Step 4.

“WHT” wire circuit open.

4

Check steering angle sensor power supply circuit
1) Measure voltage between connector terminal “E45-1” 

and vehicle body ground with ignition switch turned ON.

Is it 10 – 14V?

Go to Step 5.

“GRN/ORN” wire circuit 
open.

5

Check steering angle sensor power supply circuit
1) Turn ignition switch to OFF position.
2) Measure resistance between connector terminal “E45-2” 

and vehicle body ground.

Is resistance less than 2 

?

Go to Step 6.

“BLK” wire circuit open 
or high resistance.

6

Check steering angle sensor
1) Connect steering angle sensor connector.
2) Check steering angle sensor referring to “Steering Angle 

Sensor On-Vehicle Inspection”.

Is it good condition?

Substitute a known-
good ESP

® hydraulic 

unit / control module 
assembly and recheck.

Replace steering angle 
sensor.

No

1

Was “Electronic Stability Program Check” performed?

Go to Step 2.

Go to “Electronic 
Stability Program 
Check”.

2

Check DTC for ESP

®

1) Connect scan tool to DLC with ignition switch turned 

OFF.

2) Turn ignition switch ON and check DTC for ESP

®.

Is there any DTC(s) other than C1038 and C1090?

Go to applicable DTC 
diag. flow.

Go to Step 3.

3

Check ESP

® control module

1) Turn ignition switch to OFF position.
2) Substitute a known-good steering angle sensor.
3) Calibrate all sensors referring to “Sensor Calibration”.
4) Clear all DTC(s) and recheck DTC.

Is DTC C1038 still detected?

Substitute a known-
good ESP

® hydraulic 

unit / control module 
assembly and recheck.

Steering angle sensor 
was malfunction.

DTC check for ESP

®

1) Connect scan tool to DLC with ignition switch turned 

OFF.

2) Turn ignition switch ON and check DTC for ESP

®.

Are DTC C1034 and/or C1073 detected?

Go to applicable DTC 
diag. flow.

Go to Step 3.

3

Check sensor calibration
1) Calibrate yaw rate / G sensor assembly referring to 

“Sensor Calibration”.

2) Clear all DTC(s) and check DTC for ESP

®.

Is DTC C1039 still detected?

Go to Step 4.

Yaw rate / G sensor 
assembly calibration is 
incompleted.

4

Check yaw rate / G sensor assembly
1) Check yaw rate / G sensor assembly referring to “Yaw 

Rate / G Sensor Assembly On-Vehicle Inspection”.

Is it good condition?

Substitute a known-
good ESP

® hydraulic 

unit / control module 
assembly and recheck.

Replace yaw rate / G
