Also inspect the connections for the battery
and the connections to the keyswitch. Refer to
Troubleshooting, "Electrical Connectors - Inspect"
for details.
B. Perform a 45 N (10 lb) pull test on each of the
wires in the ECM connector that are associated
with the following connections:
•
P1:48, P1:56, and P1:57 (Unswitched positive
battery)
•
P1:61, P1:68, and P1:69 (Negative battery)
•
P1:70 (Keyswitch)
C. Check the ECM connector (Allen head screw) for
the proper torque of 6.0 N·m (55 lb in).
D. Check the harness and wiring for abrasions and
for pinch points from the battery to the ECM. Also,
check the harness and wiring for abrasions and
for pinch points from the keyswitch to the ECM.
Expected Result:
All connectors, pins, and sockets should be
completely coupled and/or inserted. The harness and
wiring should be free of corrosion, abrasion, and/or
pinch points.
Results:
•

•
Not OK – There is a problem with the connectors
or wiring.
