IPC - PCM Data Problem

Recommended Posts

Got a 1994 Seville SLS. Just had Tranny rebuilt at 115000 miles and am now getting a P047 code on ths OBD1 diag. It says "IPC - PCM Data Problem". I've also had the surging light problem which other posts have said to be caused by bad ground or possibly a faulty relay. Anyone with a better explanation found recently?

Icemanbwab,

So, have you checked the battery connections and various other electrical items under the hood yet?

By "surging lights", I assume that you mean the dash lights get dim and bright?

Are there any other codes or drivability issues?

Did this all happen after the tranny was rebuilt?

What failed in the tranny (if you happend to recal).

Add power to leave problems behind. Most braking is just - poor planning.
