Error Code 1323 - Injector Circuit Failure
1. Place ignition switch to OFF
position
and
disconnect
actuator harness from engine
ECU.
a. Inspect actuator harness
and ECU 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 and

and for missing or damaged
connector seals.
Remove dirt and moisture from
connector. Replace missing or
damaged connector seals (WP

2. Place ignition switch to OFF
position
and
disconnect
actuator harness from engine
ECU and 15-pin connector at
front of engine below rocker
arm cover. Install jumper wire
from pin 9 to pin 10 at 15-pin
connector, actuator harness
side.
3. Measure resistance from
actuator harness connector
pin 3 to pin 4. Resistance
should be less than 10 ohms.
a. If resistance is not as
specified, repair or replace
connectors (WP 0111 00).
b. If engine harness requires
replacement, notify SRA.
