DTC Troubleshooting: 102

How to Troubleshoot DTCs
Check and clear the DTCs with the HDS.
NOTE: When both the ACC and CMBS indicators come on, do the ACC system troubleshooting first (except DTC 100).
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 during the test-drive, 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.
- The ACC system and the CMBS may sometimes stop working because of the environment (weather, road conditions, driving conditions, etc.). A DTC may be stored in these cases.

DTCs that may be stored even when the system is normal:
ACC indicator does not come on, CMBS indicator comes on
DTC 88: Millimeter wave rader out of detection condition
DTC 95: Battery voltage is too high
DTC 96: Battery voltage is too low
DTC 97: CMBS offset cancel timeout
Extensive driving on a rough road or the ignition switch is turned to ON (II)/LOCK (0).
DTC 102: CMBS parking brake incomplete releasing
Parking brake not fully released, or driving with the parking brake stuck.
