Hello I have a 2002 Rubicon and I am having the usual shifting problems. The code is giving me #9 "Voltage converter circuit". Do I trust that and replace the ECM as the manual says or do I look elsewhere. I have already replaced the Angle sensor, tested the 5 prong terminal off the ECM, removed and bench tested the shift motor and checked continuity on the ground s for the ECM terminal. I am just checking here for any advise. I don't want to chase my tail forever with this thing and start replacing components that are good. I have also tried resetting the ECM as stated in the service manual Thanks for any assistance.
