How to Troubleshoot DTCs
WARNING: This page is about a different variant/trim than selected.
Check for DTCs with the HDS, then clear the DTC.
NOTE: For CMBS DTCs, refer to the DTC troubleshooting index .
Before troubleshooting, check and note these items:
- Ask the customer about the conditions when the problem occurred, and try to reproduce the same conditions for troubleshooting.
- If the symptom does not appear and the CMBS indicator does not come on while test-driving, but troubleshooting is done based on the DTC, check for poor connections or loose terminals at all connectors related to the circuit that you are troubleshooting.
- After the troubleshooting or repairs are done, clear the DTCs, and test-drive the vehicle under the same conditions as when the DTC was originally set. Make sure the CMBS indicator does not come on.
- The CMBS may sometimes stop control because of the environment (weather, road conditions, driving conditions, etc.). Intermittent failure DTCs may be stored in these cases.
