How can I be sure if my PCM is bad???


I would try disconnecting battery again. Disconnect both cables and touch them together for a few seconds. This will reset all modules. Wierd that you had so many codes after just disconnecting battery. Sometimes very hard to tell if ecm is bad.

Check eng. light on. P0601 code What can I do?


A code P0601 in most cases means the PCM has gone bad. This is possibly due to a short-circuit inside the PCM. Or, if you disconnect the wires/connector from the PCM while the battery is still connected, that may also cause this code. the most common fix is to replace and reprogram the PCM. In a few cases the dealer may be able to reflash the PCM and get it working. But more than likely the PCM will need to be replaced and reprogrammed dealership for this). The good news is it *may* be covered under your emmissions warranty. good-day!

I can't remember what a PO605 code is off-hand, but I do know that it is a PCM code, and not a BCM code. There are 2 different computers.
