Duplicating Failure Conditions
- If none of the previous tests are successful, attempt to duplicate or capture the failure conditions.
- Freeze frame/failure records data, where applicable, contain conditions present when the DTC set. Perform the following procedure:
- Review and record freeze frame/failure records data.
- Use scan tool to clear DTCs.
- Turn the key to OFF and wait 15 seconds.
- Operate the vehicle under the same conditions that were noted in freeze frame/failure records data, as closely as possible. The vehicle must also be operating within the conditions for running the DTC.
- Monitor DTC Status for DTC being tested. The scan tool will indicate RAN, when the enabling conditions have been satisfied long enough for the DTC to run. The scan tool will also indicate whether the DTC passed or failed.
- An alternate method is to drive vehicle with Digital Multimeter (DMM) connected to a suspected circuit. An abnormal reading on the DMM when problem occurs, may help you locate the problem.
