Tried to run a cylinder contribution test on AE on Ford79's truck yesterday. Got this code P1464 ACCS to PCM High During Self-Test?
Can anyone tell me what this is and how to fix it. It doesn't come up when it retrieves the codes when you first turn it on, it happens when you try to do the CC test and never completes the test.

Turn A/C-heater control switch to OFF position.
It really is that easy. All the accessories need to be turned off when doing any tests with the AE.
