DTC Troubleshooting
NOTE
Before this trouble shooting is performed, read the precautions for DTC troubleshooting referring to
"Precautions For DTC Troubleshooting: ".
Step
1 Was "Engine and Emission Control System Check"
performed?
2 Starter signal check
1) Turn OFF ignition switch.
2) Remove ECM from its bracket with ECM connectors
connected.
3) Start engine, measure voltage between "C37-22"
terminal of ECM connector and vehicle body ground.
Is voltage 0 – 1 V?
3 Wire circuit check
1) Disconnect starting motor control relay in fuse box No.2
with ignition switch turned OFF.
2) Check for proper connection to starting motor control
relay at "BLK/YEL", "BLK/RED" and "BLK" (for M/T
model) wire terminals.
3) Disconnect connector from starting motor.
4) Measure voltage between "C37-22" terminal of ECM
connector and vehicle body ground with ignition switch
turned ON.
Is voltage 0 – 1 V?
4 Wire circuit check
1) Measure voltage between "BLK/YEL" wire terminal for
coil side of starting motor control relay connector coil

Go to "Engine and
Emission Control
System Check: ".
Go to Step 3.
"BLK/YEL" wire is
shorted to power circuit.
If wires are OK,
substitute a known good
ECM and recheck.
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.
