DTC Confirmation Procedure
NOTE:
Check that the following condition is met in this “DTC Confirmation Procedure”.
•Battery voltage > 8.5 V
1)Run engine at idle speed for 1 min.
DTC Troubleshooting
| Step | Action | Yes | No |
|---|---|---|---|
| 1 |
Was “Engine and Emission Control System Check” performed?
|
Go to Step 2.
|
|
| 2 |
Fuel injector power supply circuit check
1)When ignition “OFF”, disconnect connector from fuel injector related to DTC.
2)Check for proper terminal connection to fuel injector connector.
3)If connection is OK, set ignition “ON”.
4)Check that voltage between “A1”, “B1”, “C1” or “D1” and ground is battery voltage.
Is check result OK?
|
Go to Step 3.
|
Repair or replace defective wire harness.
|
| 3 |
Fuel injector drive circuit check
1)With ignition “OFF”, disconnect “C01” and “E01” connectors from ECM.
2)Check for proper terminal connections to “C01” and “E01” connectors.
3)If connections are OK, check the following points.
•Resistance of “A2”, “B2”, “C2” or “D2” circuit: less than 1 Ω
•Resistance between each of “A2”, “B2”, “C2” and “D2” circuit and ground: infinity •Resistance between “A1” circuit terminal and “A2” circuit terminal at fuel injector connector: infinity •Resistance between “B1” circuit terminal and “B2” circuit terminal at fuel injector connector: infinity •Resistance between “C1” circuit terminal and “C2” circuit terminal at fuel injector connector: infinity •Resistance between “D1” circuit terminal and “D2” circuit terminal at fuel injector connector: infinity •Voltage of “A2”, “B2”, “C2” or “D2” circuit: approx. 0 V (When ignition is “ON”) Is check result OK?
|
Go to Step 4.
|
Repair or replace defective wire harness.
|
| 4 |
Fuel injector check
1)Check fuel injector related to DTC.
Is check result OK?
|
Replace ECM and recheck DTC.
|
Replace fuel injector related to DTC.
