What Steps Should Be Taken Before Replacing the Engine Control Module for a Failed Driver, Control Circuit, or Ground Circuit on Chrysler 300M?

Just before replacing a Pcm in a failed driver, control circuit or ground circuit, check the other related component and circuit to ensure there are no double faults causing problems. Most of the time, the driver/control circuits in a Pcm fail due to component issues, without giving many hints, as double faults often lead an engine software manager to set just a single Dtc. If both Pcm and Skim are being changed, set the Vin in the Pcm first and then you need to remove and replant the keys with the new Skim. Changing the Pcm requires the new unit to be programmed using the special Skis Secret Key stored in the Skim, engine controller and transponder. When you've replaced the Pcm, turn on the ignition with the transmission in park or neutral, select Theft Alarm, Skim and then Miscellaneous on the Drbiii(R). You should then choose Pcm Replaced from the menu options. Make sure to use your vehicle's four-digit Pin to enter the secure access mode, but know that three incorrect entries will lock it for an hour and you will need the ignition to be on for that entire time before trying again. Switch off all accessories, watch the battery's health and connect a charger if it needs to be replenished. Press Enter at the end to copy the secret key from the Skim over to the Pcm.
