Battery ground
Battery voltage (12 V) should be read.
If voltage reads 12 V, check continuity of OR-
ANGE/GREEN wire between relay connector
and pin B-16 of ECM connector. If faulty, repair
wire/connector. If wire/connectors test good, try
anewECM.
If voltage does not read 12 V, check continuity
of wire on supply side of relay. If faulty, repair
wire/connector. If wire/connectors test good, re-
fer to ELECTRICAL SYSTEM to test output side or
relay.
