No communication no 5 volt ref no spark no injectors
I have no communication with any modules no spark no injectors.
.7volts on the 5volts ref lines this has 2 5volt lines
I have good power and grounds at the computer
pin 3 of dlc has .01 volts. Pin 11 has .23 volts. CCD bus + & -
Pin 6 has .6 volts Pin 7 has .8 volts. SCI transit and receive lines
Pin 14 has -2.5 volts
Pin 15 has 10.8 volts not sure why, I don't see ABS on this van
Pin 16 has 11.2 volts. Battery a little low now.
I disconnected every sensor on the5 volt ref that is showing the wiring diagram, Map, Trans, Speed sensor, crank and cam sensors Tps even A/C pressure sensors even through they aren't on the 5 volt line,
I don't see any abs on this van or cruiser control
Thanks for any suggestions
Clip the 5 V wires up by the PCM and see if your 5 volt comes back. If it doesn't, the find another PCM.
I was thinking of doing exactly that Thanks for the suggestion
check powers and grounds at engine computer. keep in mind the ASD relay When checking for powers.
I concur with Albin here: clip the wires and see if the VREF comes back. If so, you've still got something pulling it down. If not, you need a PCM.
Yes I did disconnect the two on the transmission, I cut both 5volt ref wires at the ECM/PCM still no 5 volts coming out of the computer. We are going to look for a computer Thank you
Did you cycle the key on off on to see if the 5v is there after cutting the wires.
