I have a 1996 Dodge Grand Caravan 121,000 miles. I took the van to get inspected and the mechanic told me that I could not get it inspected because there was no power coming from the computer. The computer is working but the "plug" that hooks up to the computer is not... i obviously do not know a thing about cars :oops: but my husband knows a little and he is equally perplexed by this we have the "book" to the van as he has replaced lots of diffrent parts on the vehicle. When we asked the mechanic where we should even begin to lookto check how to fix this problem he had no answer for us... so now what? Please help!

There are power feeds from the car and from the computer.If all fuses and fusible links are good, then it may need a new PCM.We have seen them do that before,resulting in a "no communication" condition

Suggested Repair

Check the power feeds, fuses, and fusible links supplying the PCM and diagnostic connector. If those are good, the PCM may have failed and need replacement, which can cause a no-communication condition.

Conversation Summary

The owner of a 1996 Dodge Grand Caravan was told it could not be inspected because the diagnostic plug had no power from the computer, although the computer appeared to be working. The mechanic could not say where to start. The expert explained that power comes from both the vehicle and the computer, and advised checking fuses and fusible links; if they are good, a failed PCM may be causing the no-communication condition and may need replacement.
