Look in the index for diagnostic trouble codes or something similar for the ECC

John, use the procedure in Techinfo to clear the code first. ( I just did again yesterday for a 'phantom' code).

If it comes back, we need to look at those wires from the compressor to the firewall. Your FSM will show how to run full diagnostics (500 times more information than in Techinfo), but it'* VERY hard to follow. I spent 3 hours one night going through all the modes and functions to learn it.
