d. Measure resistance from
harness connector pin 18 to
positive
(+)
battery
terminal. Resistance should
be less than 10 ohms.
e. Measure resistance from
harness connector pin 28 to
positive
(+)
battery
terminal. Resistance should
be less than 10 ohms.
7. Place ignition switch in OFF
position. Disconnect OEM
harness
connector
from
engine ECU (794). Turn off
circuit breakers 51-F4 and 51-
F5. Perform the following
resistance checks. Resistance
should be greater than 100k
ohms.
a. If resistance is not as
specified, repair connectors
(WP 0111 00).
b. If harness cannot be repaired,
notify SRA to replace harness.
a. Measure resistance from
harness connector pin 7 to
all other pins in connector.
b. Measure resistance from
harness connector pin 8 to
all other pins in connector.
