PCM/ECM Module 4, Code H31?
Had the 'engine service soon' light on my ZR-1 this morning for the first time ever and did the diagnostic test with the paper clip.
Had the H31 code come up in the module 4 part. I know the H for the PCM/ECM code could be either 'current or history' but cannot find anywhere what this code stands for.
The engine service light is off now but would like to know what set the light on. Does anyone know what this code is for.
http://www.c4vettes.com lists error codes for many numbers from 12 to 72 but 31 is not one of them. :confused:
