Dtc C1015 / C1017 / C1023: Longitudinal G Sensor / Lateral G Sensor / Yaw Rate Sensor In Yaw Rate / G Sensor Assembly Failure; Dtc C1016: Stop Light Switch Circuit Failure - Suzuki Grand Vitara 2011 Manual

DTC C1015 / C1017 / C1023: Longitudinal G Sensor / Lateral G Sensor / Yaw Rate Sensor in Yaw Rate
/ G Sensor Assembly Failure
DTC Detecting Condition and Trouble Area
DTC Detecting Condition
C1015:
Longitudinal G sensor signal is out of specified range. (for
4WD vehicle)
C1017:
Lateral G sensor signal is out of specified range.
C1023:
• Yaw rate sensor signal is out of range.
• Vehicle behavior and yaw rate signal is disagreed.
DTC Troubleshooting
Step
1 Was "Electronic Stability Program Check" performed?
2 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?
3 Check sensor calibration
1) Calibrate yaw rate / G sensor assembly referring to
"Sensor Calibration".
2) Clear all DTCs and check DTC for ESP®.
Are DTC C1015, C1017 and/or C1023 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?
