DTC Advanced Diagnostics: VSA related DTCs
VSA Related DTCs
NOTE
Initial Diagnosis:
The initial on-board diagnosis occurs right after the ignition switch is turned to ON (II), or engine start/stop button is pressed to select the ON mode, and the ABS/VSA indicator comes on, and continues until the indicator goes off.
Regular Diagnosis:
The regular on-board diagnosis begins right after the ABS/VSA indicator goes off, and it continues until the ignition switch is turned to LOCK (0), or engine start/stop button is pressed to select the OFF mode.
Review "How to troubleshoot the VSA system" before doing the DTC troubleshooting procedure.
Test-drive the vehicle according to local traffic conditions and regulations. Do not test-drive on a lift unless specified.
The possible causes shown may not be a complete list of all potential problems, and it is possible that there may be other causes.
