Troubleshooting
NOTE
• Before performed trouble shooting, be sure to read the “Precautions of ECM Circuit Inspection”.
• When measuring circuit voltage, resistance and/or pulse signal at ECM connector, connect the
special tool to ECM and/or the ECM connectors referring to “Inspection of ECM and Its Circuits”.

Step Action Yes No
1Circuit fuse check
1) Disconnect connectors from ECM with ignition switch
turned OFF.
2) Check for proper connection to ECM connector at “E01-
2”, “E01-29”, “E01-60”, “E01-1”, “E01-16”, “E01-31”,
“C01-58”, “C01-15” and “C01-30” terminals.
3) If OK, check “DOME” fuse and “IG COIL” fuse for
blowing.
Are “DOME” fuse and “IG COIL” fuse in good condition?Go to Step 2. Replace fuse (s) and
check for short in
circuits connected to
fuse(s).
2Power supply circuit check
1) Measure voltage between “E01-2” terminal of ECM
connector and body ground.
Is voltage 10 – 14 V?Go to Step 3. “WHT/RED” or “WHT”
wire is open circuit.
3Ignition signal check
1) Turn ignition switch to ON position.
2) Measure voltage between “E01-29” terminal of ECM
connector and body ground.
Is voltage 10 – 14 V?Go to Step 4. “BLK/WHT” or “GRN”
wire is open circuit.
4Main relay circuit check
1) Turn ignition switch to OFF position.
2) Check “FI” fuse (1) (15 A) in individual circuit fuse box
No.1 for blowing.
3) If OK, measure voltage between “E01-60” terminal of
ECM connector and body ground.
Is voltage 10 – 14 V?Go to Step 5. Go to Step 9.
5Main relay circuit check
1) Connect connectors to ECM with ignition switch turned
OFF.
2) Turn ignition switch to ON position.
3) Measure voltage between “E01-60” terminal of ECM
connector and body ground.
Is voltage 0 – 1 V?Go to Step 7. Go to Step 6.

1) Connect connectors to ECM with ignition switch turned
OFF.
2) Turn ON ignition switch, measure each voltage between
“C01-14”, “E01-35”, “E01-34” and “C01-43” terminal of
ECM connector and vehicle body ground.
Is each voltage 4 – 6 V?ECM power and ground
circuit is in good
condition.Go to Step 12.
12Sensor power source circuit check
1) Disconnect connectors from ECM, TP sensor, MAP
sensor, A/C refrigerant pressure sensor (if equipped with
A/C) and APP sensor with ignition switch turned OFF.
2) Measure each resistance between “C01-14”, “E01-35”,
“E01-34” and “C01-43” terminal of ECM connector and
vehicle body ground.
Is each resistance infinity?Check internal short
circuit of TP sensor,
MAP sensor, A/C
refrigerant pressure
sensor (if equipped with
A/C) and/or APP
sensor.“GRY/RED”, “BRN” and/
or “RED” wire is shorted
