Question:
Looks easy to swap out the BCM. Not sure if I need to program it so the keys and everything works. Reading conflicting info on the ole internet.
Answer:
Yes, you absolutely have to have the BCM dealer programmed. It controls many many aspects of the car, like the keys, tpms, interior lighting, etc. which varies based on options. Also, the BCM and PCM, and possibly the Instrument cluster must all be programmed to work together.
if installing a new BCM, it must be programmed with as-built data for the vehicle it’s going into.
NOTE: If the BCM (body control module) did not respond to the diagnostic scan tool, As-Built Data may need to be entered as part of the repair. This step is only necessary if the BCM (body control module) is being replaced
The rest of the procedure:
1.Cary out the remaining steps only if installing a new BCM (body control module).
2.NOTE: A diagnostic scan tool should not be used to program keys for this specific step.
Program the keys.
Place the first key in the ignition lock cylinder or the backup starting location.
Refer to: Passive Anti-Theft System (PATS) (419-01C).
§ Turn the ignition lock cylinder to the RUN position or press the START/STOP button and wait approximately 6 seconds.
§ Turn the ignition lock cylinder to the OFF position or press the START/STOP button and remove the first key.
§ Place the second key in the ignition lock cylinder or the backup starting location.
§ Turn the ignition lock cylinder to the RUN position or press the START/STOP button.
3.Cary out the parameter reset.
Refer to: Anti-Theft Security Access (419-01B Passive Anti-Theft System (PATS) – Vehicles With: Push Button Start, General Procedures).
Refer to: Anti-Theft Security Access (419-01B Passive Anti-Theft System (PATS) – Vehicles With: Push Button Start, General Procedures).
4.Using a diagnostic scan tool, complete the PMI (programmable module installation) process for the BCM (body control module) following the on-screen instructions.
5.Using a diagnostic scan tool, carry out the Configuration Engine Immobilizer (CEI) configuration following the on-screen instructions (Toolbox > Body > Service Functions > CEI Lock Configuration).
6.Using a diagnostic scan tool, carry out the battery monitor sensor reset following the on-screen instructions (Toolbox > Body > BMS Reset).
7.NOTE: This step does not apply to vehicles equipped with 360 degree camera view.
If equipped with video rear parking aid, using a diagnostic scan tool, cary out the new module initialization following the on-screen instructions (Toolbox > Electrical > Service Functions > LIN New Module Initialization).
8.Configure the customer preference programmable parameters.
Refer to: Module Configuration – System Operation and Component Description (418-01 Module Configuration, Description and Operation).
9.Train the tire pressure sensors.
Refer to: Tire Pressure Monitoring System (TPMS) Sensor Location Calibration (204-04 Tire Pressure Monitoring System (TPMS)).
10.Cary out the BCM (body control module) self-test (must include an on-demand self-test) and then repeat the self-test to confirm all DTC (diagnostic trouble code) have been cleared.
11.NOTE: This step applies only to Fusion Energi.
Cary out the PCM (powertrain control module) Keep Alive Memory (KAM) reset following the scan tool on screen instructions (Toolbox > Powertrain > Reset KAM > PCM).
12.Using a diagnostic scan tool, complete the PMI (programmable module installation) process for the PAM (parking assist control module) following the on-screen instructions.
The last, I’d like to recommend Ford diagnostic tool:
