Analog Volt-Ohmmeter (VOM)
1)
Turn engine off and allow it to cool. Turn all accessories off. Disconnect PCM STI jumper from ground. Place shift lever in Park (A/T) or Neutral (M/T).
2)
Reconnect jumper wire between ground and PCM STI terminal at DLC connector. Using VOM, connect positive (+) lead to SML terminal at DLC connector. Connect negative (-) lead to engine ground.
3)
Turn ignition on. Test EEC input devices individually. See SWITCH MONITOR TEST SPECIFICATIONS table. Ensure input device is deactivated after test. Leaving device on while testing another device may produce false results and cause misdiagnosis.
4)
If input device fails test (reading on VOM is not as indicated), perform related circuit test. See SWITCH MONITOR TEST SPECIFICATIONS table. If all input devices fail, check Switch Monitor Light (SML) circuit. See TEST SML. If all input devices test okay and no code is stored in PCM memory, EEC system test is complete.
