CORRECTIVE ACTION
Error Code 1434 - Unswitched Battery Supply
Circuit Failure
1. Ensure that ignition switch is
in OFF position. Disconnect
OEM harness from engine
ECU (794) and disconnect
positive
and
negative
terminals
from
battery.
Perform
the
following
resistance checks:
If resistance is not as specified,
notify SRA to repair or replace
engine harness.
a. Measure resistance from
OEM harness connector
pin 18 to positive (+)
battery
terminal.
Resistance should be less
than 10 ohms.
