DTC Detecting Condition and Trouble Area
DTC Detecting Condition
CAN line communication error in ESP® control module
and yaw rate / G sensor assembly is detected.
DTC Troubleshooting
Step
1 Was "Electronic Stability Program Check" performed?
2 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?
3 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
module and yaw rate / G sensor assembly opened, shorted
or high resistance?
