Measure voltage between ground and SDM connector terminal No. 9 (Green wire) and No. 10 (Green/Red wire). See Figure. If voltage is less than one volt, substitute a known-good SDM and retest system. If voltage is more than one volt, repair short to voltage in Green wire or Green/Red wire. See WIRE REPAIR .
