DTC Detecting Condition and Trouble Area
DTC Detecting Condition
ESP® control module rolling counter failure is detected by
steering angle sensor.
DTC Troubleshooting
Step
1 Was "Electronic Stability Program Check" performed?
2 Check DTC
1) Connect scan tool to DLC with ignition switch turned
OFF.
2) Turn ignition switch ON and check DTC.
Is there any DTC(s) other than C1038 and C1090?
3 Check ESP® control module
1) Turn ignition switch to OFF position.
2) Substitute a known-good steering angle sensor.
3) Calibrate steering angle sensors referring to "Sensor
Calibration".
4) Clear all DTC(s) and recheck DTC.
Is DTC C1038 still detected?

DTC Troubleshooting
Step
1 Was "Electronic Stability Program Check" performed?
2 DTC check
1) Connect scan tool to DLC with ignition switch turned
OFF.
2) Turn ignition switch ON and check DTC.
Are DTC C1034 and/or C1073 detected?
3 Check sensor calibration
1) Calibrate yaw rate / G sensor assembly referring to
"Sensor Calibration".
2) Clear all DTC(s) and recheck DTC.
Is DTC C1039 still detected?
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?
