Procedure # 1

(For 3.0L vehicles with PCMs that have tear tag numbers of JYB2 or JYB3. For all other PCM tear tag numbers, refer to Procedure 2.)

Note:
When replacing a powertrain control module (PCM), the following items are required:

^ WDS with B20.12 or later software loaded.

^ Minimum two ignition keys for reprogramming PATS (be sure to ask customer for ALL spare keys).

^ Obtain new PCM part number AJ08-18-881F.

^ With old PCM still in vehicle follow procedure below.

Note:
When performing this procedure, if the WDS PTU is not docked and connected to 115V-120V, we recommend that a battery charger be installed on the vehicle battery and turned ON to a maximum charge of no more than 20 AMPS to keep the vehicle battery up to capacity. If you exceed 20 AMPS it will damage the WDS PTU.
