Hi Daryl,

Thanx for the feedback. Do you know which signals or outputs cause the ECS lamp
to light? If we knew this at least that lamp being lit or not would tell whether
the "monitored" group contained the problem.. When I get a minute(ha,ha,ha,!)I'm
going to rig an LED using my 25 pin BOB and set some faults in my '91 MV. If
this function can give me a blinking pass-fail(albeit broad)on a group of signals,
I still may wire an LED in the inst cluster.

While we're talking, why does the DCM check the main relay control circuit power
via pin 23? If the main relay control power is missing - the DCM is dead!!!

Regards,   John
