I think I made the mistake of cleaning my engine yesterday. I use gunk cleaner and wash it down. Cover the intake and PCM with plastic bags. After rinse and dry it I turn it on and start fine and runs good. Today when I turn on the engine the engine light on and I use my scan it reads code "P1698- No CCD/J1850 Message from TCM/PCM". The gauges work fine and the wires look fine. Should I disconnect the battery plug it back. I hope I didn't mess up my PCM just had that replace 3 years and is costly.

 

Reset it with taking the Neg. battery cable off see if it will come back on

 

Yea ok i will try that hopefully it will not come back on

 

Sounds like you may have got something wet. Buy you some wire dryer and die-electric grease. Pull plugs one at a time spray with wire dryer (dries up the water). then alittle dab of die electric grease. Its time consuming, however it keeps the water out so it doesn't happin again.

 

I disconnect the battery and replug it, drove 40 miles today and I scan it again and it shows no codes.... yet. Still gonna have to wait and see

 

Yeah there is no certain amount of miles until the CEL comes back on just when your truck is ready

 

Ok after driving 300 miles the light never came back, i guess it was just a glitch

 

Your computer saw something wrong with the cluster, but since it hasnt came back on it is either "fixed" or just waiting to get moved back to the spot it messed up.

GLAD its working for ya tho

 

I think is "fixed" I keep updated in 2 weeks

 

Alls you can do is wait!
