The Battery must be in a charged state before doing diagnosis. To use the tests under other conditions could result in misdiagnosis.
- Perform the On-Board Diagnostic System Check, to be certain that no Diagnostic Trouble Codes (DTCs) are stored in PCM memory which may lead to misdiagnosis. Refer to Powertrain Management. Testing and Inspection
