WARNING: This page is about a different car, the 1996 Acura SLX. However, it is still accessible from the selected car via links, so may be relevant.
An open or short to ground in Ignition Control (IC) or by-pass circuit will cause PCM to turn on Malfunction Indicator Light (MIL) and confirm fault by setting a related trouble code. Refer to TESTS W/CODES article.
