REM Module Interface

WARNING: This page is about a different car, the 2002 Ford Windstar. However, it is still accessible from the selected car via links, so may be relevant.

Power sliding door open operation requires the vehicle to be in PARK and the vehicle speed to be less than 10 km/h (6 mph). The rear electronics module (REM) receives information over the J1850 network from the powertrain control module (PCM) for the PRNDL position and anti-lock brake system/traction control module (ABS/TC) for the vehicle speed.

If the vehicle is in PARK, the REM will ground the PARK (enable) circuit to the power sliding door modules. If the vehicle speed is less than 10 km/h (6 mph), the REM will ground the vehicle speed circuit to the power sliding door modules. As long as these two circuits are at ground, normal power sliding door open operation can be carried out. The power sliding door can be closed regardless of the PARK or vehicle speed status.

The REM will prevent power sliding door open operation in the event either of these two messages were invalid or missing. These two inputs to the REM have network DTCs. If either of these DTCs are retrieved and the power sliding door is not operating, repair these DTCs first.
