Computer Relearn Procedures: Other Mitsubishi Lancer IX

ENGINE CONTROLS

After disconnecting battery, electronic control system data from engine, automatic transaxle and other memory systems will be erased. As a result, engine speed may become unstable and harsh or poor transmission/transaxle shift quality may occur. If engine speed becomes unstable, go to ENGINE CONTROL MODULE . Harsh or poor transmission/transaxle shift quality will become smoother after several changes in speed. Memory data settings made by vehicle owner will need to be reestablished using relevant procedures in owners manual.

If Powertrain Control Module (PCM) has been replaced, go to PROGRAMMING .
