| 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. |
