  3. Turn ignition switch to OFF position. Disconnect RDCM Red, 26-pin connector C1. Turn ignition switch to RUN position. Check voltage between RDCM harness connector C1 terminal No. 1 (Orange wire) and ground. See Fig 1 . If 8.5-16.3 volts exists, go to step  7 . If 8.5-16.3 volts does not exist, go to step  5 .
