EPS Related DTCs
NOTE
|
|
Initial Diagnosis:
The initial on-board diagnosis occurs right after the ignition switch is turned to ON (II), or the engine start/stop button is pressed to select the ON mode, and the EPS indicator comes on, and continues until the indicator goes off. |
|
|
Regular Diagnosis:
The regular on-board diagnosis begins right after the EPS indicator goes off, and it continues until the ignition switch is turned to LOCK (0), or the engine start/stop button is pressed to select the OFF mode. |
|
|
Review "How to troubleshoot the EPS 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. |
