Multiple control modual and sensor errors
im coming up with these codes
u011-20 po451-ff po 710-ff po713-ff p1876 p1832
b1318 u2023-20
and then under dtc I’m getting these
1.4x4m (control module)
3.pcm (power control module)
5.gem/sjb (generic electronic module / smart junction box)
ic (instrument cluster)
4.acm (audio control module)
6.tbc (trailer break control module)
everything Seems to be working normally except radio and sometimes transmission seems to shift a bit hard. (Rarely). Cannot clear pcm and 4x4 codes.
I did change transmission and transfer case fluids. No metal shavings inside. 190k miles
truck does ride a bit rough in general. Battery voltage is 12.47. I thought hopefully someone can zero in in on what’s going on before I start buying module after module sensor after sensor. Thanks for any inpu
