Generator Control System Description
Refer to “Generator Control System Description”.3
Wire circuit check
1) Disconnect starting motor control relay in individual
circuit fuse box No.1 with ignition switch turned OFF.
2) Check for proper connection to starting motor control relay at “RED/WHT”, “RED”, “WHT”, “YEL” (for A/T
model) and “YEL/GRN” (for M/T model) wire terminals.
3) Disconnect connector from starting motor.
4) Measure voltage between “C37-48” terminal of ECM connector and vehicle body ground with ignition switch
turned ON.
Is voltage 0 – 1 V? Go to Step 4. For A/T model, “YEL” or
“YEL/GRN” wire is
shorted to power circuit.
For M/T model, “YEL/
GRN” wire is shorted to
power circuit.
If wires are OK,
substitute a known good
ECM and recheck.
4 Wire circuit check
1) Measure voltage between “RED/WHT” wire terminal of
starting motor control relay connector and vehicle body
ground with ignition switch turned ON.
Is voltage 0 – 1 V? Check starting motor
control relay. If OK,
substitute a known-
good ECM and recheck.
Faulty ignition switch,
check ignition switch
referring to “Ignition
Switch Inspection in
Section 9C”.
If ignition switch is OK,
check for short circuit
between ignition switch
and starting motor
control relay to power
circuit.
