(A): 09932-76010

With ignition switch turned ON, measure voltage between "L04-19" terminal and body ground, and between "L04-20" terminal and body ground (for DTC B1364).
Measure voltage between "L04-21" terminal and body ground, and between "L04-22" terminal and body ground (for DTC B1368).






Is each measured voltage 0 V?
YES -
Substitute a known-good SDM and recheck.
NO -
