OD & CC where did they go?
Everything been's too good. No problems, tranny holding up until I can get my 47RH built...
Then the other shoe dropped - big time.
Lost OD and CC yesterday. I've checked the wires and plugs. All seems to be ok.
Speedo and tach still work so I don't think it's the PCM...
Anyone have any ideas ?
Thanks in advance.
PS I'm not against hard wiring a switch for the OD but really miss the CC...

PCM has nothing to do with the speedo, they share the VSS. A working speedo does not mean that the PCM is getting the message.
I would check continuity between the orange/white wire on the VSS plug and cavity 47 (also has an orange/white wire - go figure) on the PCM plug.
I'm assuming your truck has not been converted to an old style voltage regulator?

I'll check it in the AM. That's one wire and plug I didn't check...
No I haven't converted regulators.

The reason I asked... My wifes former '00 Plymouth mimi-van dropped the CC & something else on the steering wheel (radio controls?), but the horn continued to function. Ended up being the clock spring anyway... luckily only $59 "dealer cost" from my 5Star wrencher bud to throw in after work one day.
Wouldn't even let me buy him a cold one for his trouble!

So the VSS signal is getting to the PCM...
Will the truck start in Drive?

No
AS I said - everything I could check appears normal.
A/C works, tach works, speedo works...
I'm real close to hardwiring a switch for the OD...IF no other reason than to check and see if the problem is mechanical...
I don't think the CC will kick in unless the OD is on. I don't remember trying to engage CC with the OD locked off...

Start the truck, unplug the NSS, and go for a ride. See if you get OD and cruise back.
Check for a ground at cavity 30 on the PCM connector with the shifter in Drive.
