Engine Control Module: Service and Repair
Programming the PCM/ECM/SKIM
The SKIS Secret Key is an ID code that is unique to each SKIM. This code is programmed and stored in the SKIM, the PCM/ECM, and each ignition
key transponder chip. When the PCM/ECM or SKIM is replaced, it is necessary to program the Secret Key into the new modules using a diagnostic scan
tool. Follow the programming steps outlined in the diagnostic scan tool menu for the module being replaced as appropriate.
NOTE:
-
Be certain to enter the correct country code for the SKIM. If the incorrect country code is programmed into the SKIM, it cannot be changed and
the SKIM must be replaced.
-
If the PCM/ECM and the SKIM are replaced at the same time, all vehicle ignition keys will need to be replaced and the new keys programmed
into the new SKIM.
-
Programming the PCM/ECM or SKIM is done using a diagnostic scan tool and a PIN to enter secure access mode. If three attempts are made to
enter secure access mode using an incorrect PIN, secure access mode will be locked out for one hour. To exit this lockout mode, turn the ignition
to the RUN position for one hour then enter the correct PIN. (Ensure all accessories are turned OFF. Also monitor the battery state and connect a
battery charger if necessary).
