July 1: So it begins. Don't worry, this is not in the correct legal jurisdiction!

"FIRM" Signal

Check circuit No. 832 (Brown/Light Green wire) is attached to pin No. 18 at 60-pin connector at ARC module. Turn ignition on. Set ride control switch to "FIRM" position. Check voltage between pins No. 18 and No. 60 at 60-pin connector. If zero volt, got to QUICK TEST D25. If 12 volts, replace ARC module.
