Vehicle Control Module (VCM) Replacement/Programming
CAUTION: In order to prevent possible electrostatic discharge (ESD) damage to the VCM, do not touch the connector pins or soldered components on the circuit board.
" To prevent internal VCM damage, the ignition must be turned OFF before disconnecting or reconnecting power to the VCM (for example, battery cable, VCM fuse, jumper cables, etc.).
" When replacing the production VCM with a service VCM (controller), it is important to transfer the broadcast code and production VCM number to the service VCM label. This will allow positive identification of VCM parts throughout the service life of the vehicle.
" Service of the VCM consists of either replacement of the VCM or reprogramming of the VCM. If the diagnostics call for replacement of the VCM, it will be necessary to transfer the Electronic Spark Control Module (PROM) and program the VCM using the procedure in this section.
" The PROM / Electronic Spark Control Module must be transferred to the replacement VCM.
" Do not remove the cover of the PROM. Use of an unapproved PROM removal method may cause damage to the PROM or the socket.
" The replacement VCM must be programmed before the vehicle will run.
" The replacement VCM must also have the VTD Password Learn Procedure completed before the vehicle will run.
" The replacement VCM must also have the CKP System Variation Learn Procedure completed. If this procedure is not completed a DTC P1336 will set.
