Hi everyone, still trying to fix the ABS on my 1990 6-speed coupe.
According to my manual I should be able to read out the codes via a CCM readout in the dash LCD.
When I short out the contact on the ALDL connector (G or H? I can't remember but I know I shorted out the right one!) I should be able to see a 9.0 displayed in the dash and from there I should be able to extract codes.
I do get the codes for the ECM (1.0 range) and CCM (4.0 range). Am I to deduce that my ABS ECM isn't communicating with the CCM?
Although many of you will know this already from my previous posts on the subject (epecially Vigman - thanks for your help so far) when I extract codes via the DIC I get a code 31 (right rear sensor) 71 (EBCM internal fault) and 25 (left front sensor).
Previously it looked likely that my EBCM (ABS ECM or module) was probably dead. Does the above look like further evidence to support this?
This was one last desperate question because getting a new EBCM is a real hassle for me in the UK. Anyone know any good sources for this part? I contacted GM but they told me they won't deal with anyone or give help to anyone outside the USA. Wonder if they'd say the same thing if I'd just parted with $50,000 for a new Z06?
