Search this forum this category all forums for All words Any words Whole Phrase (search options) Auto Repair Home>> Automotive Repair>> Car Troubleshooting jundtman New User May 8, 2017, 9:11 AM Post #1 of 3 (1512 views) Bad PCM? Sign In Just started my 2006 Ford Taurus and ABS, brake light, battery light, and check engine light came on. Thought it was the alternator but checked out OK. Tried both of my OBD II testers, but no communication to the PCM. Car runs but have noticed some hitching in the transmission. I checked all fuses and wires, they are fine. Do I have a bad PCM?

Sign In You're probably going to have to take it to a shop that has an enhanced scan tool to see if the PCM isn't the only thing that can't be communicated with. Troubleshooting network issues is beyond the scope of DIY. Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved. jundtman New User May 8, 2017, 10:12 AM Post #3 of 3 (1491 views) Re: Bad PCM? Sign In Thanks for the reply. Guess I'm going to have to do that. Also saw that miles to E and my car miles are both blank, just hash marks.   Automotive Repair     Auto Body Repair and Refinishing     Heating or AC Issues     Electrical and Wiring     Brake Systems     Car Stereo Repair Advice     General Discussions     Car Making Funny Noises     Engine Fault Codes     Engine Troubles     Exhaust Systems     Steering and Suspension     Transmission Troubles     Tricks of the Trade Automotive World     General Discussions     Antique Car Talk     Car Shows and Events     The Bargin Bin     Motor Vehicle Inspection     Car Care Tips     Traffic Tickets     Gasoline, Motor Oils, Concept Cars and Engines     Auto Insurance, Financing, Leases, Warranties Truck Repair     General Discussions     Truck Engine Repair     Truck Suspension Repair Motorcycle Repair     General Discussions     Motorcycle Engine Repair CarJunky     Open Posting     Board FAQ's     New Board Suggestions
