Re: 95 Bonnie QDM issues
Qdms are devices in the pcm that control various solenoids for engine and trans controls, normally a qdm code inidicates a short or open circuit in that particular qdm circuit or solenoid. Replacing the pcm is not the answer

Re: 95 Bonnie QDM issues
You need to know whats on that Quad Driver Module so that you can test those items as the PCM has seen a problem with one of the items on that circuit...
