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 id= le position is lost.

 

Perform the following procedure to return the learned idle to the corre= ct position:

 

Automatic Transmission:

 

1        &n= bsp;           Turn off the ignition

2        &n= bsp;           Restore the P= CM battery feed

3        &n= bsp;           Turn Off the = AC controls

4        &n= bsp;           Set the parki= ng brake and block the drive wheels

5        &n= bsp;           Start the eng= ine

6        &n= bsp;           Allow the eng= ine coolant temperature to reach 176 degrees F

7        &n= bsp;           Shift the transmission selector into the drive range

8        &n= bsp;           Allow the eng= ine to idle for 5 minutes

9        &n= bsp;           Turn on the AC controls  (Omit for 2000-02 model)

10        &= nbsp;       Allow the eng= ine to idle for 5 minutes (Omit for 2000-02 model)

11        &= nbsp;       Shift the transmission selector into Park

12        &= nbsp;       Allow the eng= ine to idle for 5 minutes (Omit for 2000-02 model)

13        &= nbsp;       Turn off the = AC controls (Omit for 2000-02 model)

14        &= nbsp;       Allow the eng= ine to idle for 5 minutes

15        &= nbsp;       Turn off the engine for 15 seconds

 

Manual Transmission:

 

1        &n= bsp;           Turn Off the ignition

2        &n= bsp;           Restore the P= CM battery feed

3        &n= bsp;           Turn Off the = AC controls

4        &n= bsp;           Set the parki= ng brake and block the drive wheels

5        &n= bsp;           Transmission = in neutral

6        &n= bsp;           Start the eng= ine

7        &n= bsp;           Allow the eng= ine coolant temperature to reach 176 degrees F

8        &n= bsp;           Turn on the AC controls (Omit for 2000-02 model)

9        &n= bsp;           Allow the eng= ine to idle for 5 minutes (Omit for 2000-02 model)

10        &= nbsp;       Turn off the = AC controls (Omit for 2000-02 model)

11        &= nbsp;       Allow the eng= ine to idle for 5 minutes

12        &= nbsp;       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 wi= ll add it at a later time.
