DTC Troubleshooting


1. Was "Engine and Emission Control System Check" performed?
YES
Go to Step 2.
NO
Go to Engine and Emission Control System Check Engine and Emission Control System Check.
2. IMT valve actuator drive circuit check
Confirm that ignition mode of keyless push start system is in "OFF".
Disconnect "C01, "E01" and IMT valve actuator connectors.
Check for proper terminal connection to "C01, "E01" and IMT valve actuator connectors.
If connection are OK, check the following points.
Resistance of "A1" and "A2" circuits: less than 1
Resistance of "A1" and "A2" circuits between IMT valve actuator connector and ground: infinity
Resistance of between "A1" circuit terminal and each terminal at IMT valve connector: infinity
Voltage of "A1" and "A2" circuits: 0 - 1 V (with ignition mode of keyless push start system in "ON")
Are they in good condition?
YES
Go to Step 3.
NO
Repair or replace "A1" and "A2" circuits.
3. IMT valve actuator check
Check IMT valve actuator. IMT Valve Actuator Inspection
Is it in good condition?
YES
Replace ECM and recheck DTC. Service and Repair
NO
Replace IMT valve actuator. IMT Valve Actuator Inspection
