How to Remove the ECM/PCM for Testing
If the inspection for a trouble code requires voltage or resistance checks at the ECM/PCM connectors, remove the ECM/PCM and test it:
1. Make sure you have the anti-theft code for the radio, then write down the radio station presets.
2. Disconnect the negative cable from the battery.
3. Remove glove box.
4. Disconnect the gray 20P ECM/PCM wire harness connector, and remove it from the ECM/PCM mounting bracket. Disconnect the 7P mode
control motor connector. Remove PGM-FI main relay 2 (A). Remove the ECM/PCM mounting bolt (B) and the bracket.

ECM/PCM Idle Learn Procedure
ECM/PCM Idle Learn Procedure
NOTE: The ECM/PCM reset procedure and disconnecting the battery or the No.6 ECU (ECM/PCM) (15 A) fuse cancels the ECM/PCM memory for
idle control. The following procedure is needed after the ECM/PCM reset procedure and reconnecting the battery or the No.6 ECU (ECM/PCM) (15 A)
fuse.
1. Start the engine. Hold the engine at 3,000 rpm with no load (in Park or neutral) until the radiator fan comes on.

-
Transmission in Park or neutral
