1. Ignition switch
2. Transmission range switch (A/T)
3. Starter motor
DTC detecting condition
Possible cause
• Low voltage at terminal “C41-30” when cranking engine.
or
• High voltage at terminal “C41-30” after starting engine.
*2 driving cycle detection logic, continuous monitoring
• “BLK/YEL” circuit open
• ECM malfunction
Step
Action
Yes
No
1
Was “Engine and Emission Control System Check”
performed?
Go to Step 2.
Go to “Engine and
Emission Control
System Check”.
2
Terminal voltage check
1) Disconnect connectors from ECM with ignition switch
turned OFF.
2) Remove ECM from vehicle body and then connect
connectors to ECM.
3) Check for voltage at terminal “C41-30” of ECM
connector connected, under the following condition.
Terminal voltage
While engine cranking: 6 – 10 V
After starting engine: 0 V
Is voltage as specified?
Poor “C41-30”
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.
“BLK/YEL” circuit open.
