3. Remove XK12 connector
from relay board. Check
resistance between XK12
connector pin 5 and X16 pin
1. Resistance should be less
than 10 ohms.
If resistance is not as specified,
notify SRA.
4. Disconnect 31-pin harness
connector on left side of
engine to rear of engine ECU.
Measure resistance from pin
20 of 31-pin connector to X16
pin 1. Resistance should be
less than 10 ohms.
If resistance is not as specified,
notify SRA.
5. Ensure that ignition switch is
in OFF position. Disconnect
actuator harness connector
from engine ECU (794).
a. Inspect actuator harness
and
engine
ECU
connectors
for
dirty,
corroded, bent, broken, and
pushed back or extended
pins.
Clean and repair connector(s) as
required (WP 0111 00).
b. Check actuator harness and
engine ECU for dirt or
moisture in or on the
connectors and for missing
or

connector
seals.
Remove dirt and moisture from
connector. Replace missing or
damaged connector seals (WP
0111 00).
6. Place ignition switch in OFF
