Hello
Hope someone out there has a solution to my problem, any info would be greatly appreciated.
My truck has developed 3 codes that I believe are all connected? P2509, U1421 and P0381
P2509 Intermitent electrical signal to ECM
U1421 Implausable ignition key off time.
P0381 Glow warning lamp circuit malfunction.
And every once in a while I loose my Bus signal my dash and wipers go haywire and goes back to normal on its own?
My truck runs fine and everything seems to work Ok.
I did take my TIPM out and completely apart removed all the fuses relays and breakers washed it 99% alcohol, blew it dry reassembled and plugged it all back but made no difference in the codes, there was no obvious corrosion or broken pins etc.
