CORRECTIVE ACTION
Error Code 1312 - Injector Circuit Failure
1. Place ignition switch to OFF
position
and
disconnect
actuator harness from engine
ECU
and
from
15-pin
connector at front of engine
below rocker arm cover.
a. Inspect actuator harness,
actuator harness connector,
and 15-pin connector for
dirty,
corroded,
bent,
broken, pushed back, and
extended pins.
Clean and repair connector(s) as
required (WP 0111 00).
b. Check actuator harness,
actuator harness connector,
and 15-pin connector for
dirt or moisture in or on
connector and for missing
or
damaged
connector
seals.
Remove dirt and moisture from
connector. Replace missing or
damaged connector seals (WP
0111 00).
2. Place ignition switch to OFF
position
and
disconnect
actuator harness and sensor
harness from engine ECU and
actuator harness from 15-pin
connector at front of engine
below rocker arm cover.
Perform
the
following
resistance checks.
a. Measure resistance from
actuator harness connector
pin 3 to all other pins in
actuator harness connector.
Resistance
should
be
greater than 100k ohms.
a. If resistance is not as
specified, repair or replace
connectors (WP 0111 00).
b. If internal actuator harness
requires replacement, notify
SRA.
