Programming and Relearning

General Description
The Electronically Erasable Programmable Read Only Memory (EEPROM) is a permanent memory that is physically soldered within the PCM.

The EEPROM contains program and calibration information that the PCM needs to control powertrain operation.

EEPROM Programming
Step-up-Ensure that the following conditions have been met:
- The battery is fully charged.
- The ignition is "ON."
- The Vehicle Interface Module cable connection at the DLC is secure.

Program the PCM using the latest software matching the vehicle. Refer to up-to-date DTCS equipment user's instructions.

If the PCM fails to program, proceed as follows:
- Ensure that all PCM connections are OK.
- Check the ITCS equipment for the latest software version.
- Attempt to program the PCM. If the PCM still cannot be programmed properly, replace the PCM. The replacement PCM must be programmed.

Functional Check
1. Perform the On-Board Diagnostic System Check.
2. Start the engine and run for one minute.
3. Scan for DTCs using the Tech 2.
