System Diagnosis

Important:
^ The following tests are designed for engines and batteries at normal operating temperatures and assume that there are no engine symptoms that would cause a no-start condition. The battery must be in a charged state before doing diagnosis. To use tests under other conditions could result in misdiagnosis.
^ Perform the On-Board Diagnostic System Check described in Engine Controls to be certain no Powertrain Control Module (PCM) or IPC trouble codes are stored in memory which, if ignored, may lead to a misdiagnosis.
