(a) Turn battery disconnect and engine
start switches to OFF position (TM 5-
3805-291-10).
(b) Wiring harness remains disconnected
from switch.
(c) Disconnect wiring harness
connector(s) from powertrain ECM
(WP 0063 00).
(d) Measure resistance between contacts

5. Check switch circuits in wiring harness.
(a) Wiring harness remains disconnected
from ECM and switch.
(b) At wiring harness connector for switch,
connect a jumper wire between contact
