1A-136 Engine General Information and Diagnosis:
Step
2 Signal circuit check
1) Turn OFF ignition switch.
2) Remove ECM from its bracket with ECM connectors
connected.
3) Measure voltage at terminal "C37-48" of ECM connector,
under following condition.
Voltage at terminal "C37-48" of ECM connector
While engine cranking: 6 – 14 V
After starting engine: 0 – 1 V
Is each voltage within specified range?

DTC Detecting Condition and Trouble Area
DTC detecting condition
Engine starter signal is high voltage for 180 seconds
continuously while engine is running.
(2 driving cycle detection logic)
DTC Confirmation Procedure
1) With ignition switch turned OFF, connect scan tool.
2) Turn ON ignition switch and clear DTC using scan tool.
3) Start engine and run it at idle for 3 min. or more.

DTC Troubleshooting
NOTE
• 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".
• Upon completion of inspection and repair work, perform "DTC Confirmation Procedure" and
confirm that the trouble has been corrected.
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 "C37-48"
terminal of ECM connector and vehicle body ground.
Is voltage 0 – 1 V?

Action
Yes
Poor "C37-48"
connection or
intermittent trouble.
Check for intermittent
referring to "Intermittent
and Poor Connection
Inspection in Section
00".
If wire and connections
are OK, substitute a
known-good ECM and
recheck.
