1
Was “Electronic Stability Program Check” performed?
Go to Step 2.
Go to “Electronic
Stability Program
Check”.
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
®.
Is DTC C1057 detected?
Go to applicable DTC
diag. flow.
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 referring to
“Intermittent and Poor
Connection Inspection
in Section 00”.
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.
