PCM Idle Learn Procedure:

Anytime the PCM or the battery is disconnected, the PCM loses power or the PCM is reprogrammed, the PCM�s learned idle position is lost.

Perform the following procedure to return the learned idle to the correct position:

Automatic Transmission:

1 Turn off the ignition

2 Restore the PCM battery feed

3 Turn Off the AC controls

4 Set the parking brake and block the drive wheels

5 Start the engine

6 Allow the engine coolant temperature to reach 176 degrees F

7 Shift the transmission selector into the drive range

8 Allow the engine to idle for 5 minutes

9 Turn on the AC controls� (Omit for 2000-02 model)

10 Allow the engine to idle for 5 minutes (Omit for 2000-02 model)

11 Shift the transmission selector into Park

12 Allow the engine to idle for 5 minutes (Omit for 2000-02 model)

13 Turn off the AC controls (Omit for 2000-02 model)

14 Allow the engine to idle for 5 minutes

15 Turn off the engine for 15 seconds

Manual Transmission:

1 Turn Off the ignition

2 Restore the PCM battery feed

3 Turn Off the AC controls

4 Set the parking brake and block the drive wheels

5 Transmission in neutral

6 Start the engine

7 Allow the engine coolant temperature to reach 176 degrees F

8 Turn on the AC controls (Omit for 2000-02 model)

9 Allow the engine to idle for 5 minutes (Omit for 2000-02 model)

10 Turn off the AC controls (Omit for 2000-02 model)

11 Allow the engine to idle for 5 minutes

12 Turn off the engine for 15 seconds

If a new PCM is installed, you must perform the CKP (Crankshaft Position Sensor) System Variation learn.� If you need that information, I will add it at a later time.
