Vehicle Damage Warnings

1. Always disconnect the battery cable prior to service or replacement of electronic engine control components.

NOTE: When the battery has been disconnected and reconnected, some abnormal drive symptoms may occur while the Powertrain Control Module (PCM) relearns its adaptive strategy. The vehicle may need to be driven 10 miles or more to relearn the strategy.

2. Follow procedures provided in Computers & Controls-Testing & Inspection.
3. Disconnect electronic engine controls from wire harness before measuring for continuity, resistance or energizing with a B+ source.
4. Never measure voltage or resistance directly at the PCM.
