Jeep Flash Update

April 28, 2020

This bulletin applies to 2019-2020 Jeep Compass vehicles. Customers may experience a MIL on. DTC B25C9 (driver door ajar switch 2 stuck closed) may be stored in the PCM. In addition, the engine may not restart when in engine stop/start (ESS) mode.

Customers will have to shift into park and cycle the ignition to start the engine again. The engine may crank but not start, and a message may appear on the instrument panel (“press brake and push ignition button to start”). After this happens, they must perform a key cycle function with their foot off the brake. The engine will restart normally. 

Another possible concern is that the vehicle theft alarm may trigger randomly, and the automatic rain sensing wipers may be inoperative when the engine is restarting from stop & start.

Reprogramming is required as long as this is not an active fault. Note: If B25C9 is an active fault, normal diagnostic must be performed. The software update will not correct an active DTC.

As long as the DTC is not an active fault, reprogram the BCM with the latest software. Using wiTECH, restore vehicle configuration, perform proxy configuration alignment and perform a BCM hard reset (under the :Guided Diagnostic” tab. Perform an ignition cycle and start the engine. Clear any DTCs that may have set.
