PIM Reprogramming
When PIM reprogramming must be performed, refer to Service Programming System (SPS) .
Insure the following conditions exist in order to prepare for PIM programming or reprogramming:
- The battery is fully charged.
- The ignition switch is in the RUN position.
- The Techline equipment cable connection at the data link connector (DLC) is secure.
Program the PIM using the latest software matching the vehicle. Refer to up-to-date Techline equipment user instructions.
If the PIM fails to program, proceed as follows:
- Insure the DLC and PIM connections are good.
- Inspect the Techline equipment for the latest software version.
- Attempt to program the PIM. If the PIM still cannot be programmed properly, replace the PIM.
