MIL Circuit [05/2013 - 01/2014]: Procedure
- CHECK THAT MIL IS ILLUMINATED
- Perform troubleshooting in accordance with the table below.RESULT
Result Proceed to MIL remains on A MIL does not illuminate B
B → See step 5
A: Go to next step
- Perform troubleshooting in accordance with the table below.
- CHECK WHETHER MIL TURNS OFF
- Connect the Techstream to the DLC3.
- Turn the ignition switch to ON.
- Turn the Techstream on.
- Enter the following menus: Powertrain / Engine / Trouble Codes.
- Check if any DTCs have been stored. Note down any DTCs.
- Clear the DTCs. Refer to DTC CHECK / CLEAR [05/2013 - 01/2014] .
- Check if the MIL goes off.
OK
MIL goes off.
NG → See step 3
OK → See step 8
- CHECK HARNESS AND CONNECTOR (CHECK FOR SHORT IN WIRE HARNESS)
- Disconnect the ECM connector.
- Turn the ignition switch to ON.
- Check that the MIL is not illuminated.
OK
MIL is not illuminated.
NG → See step 4
OK → See step 9
- CHECK HARNESS AND CONNECTOR (COMBINATION METER - ECM)
- Disconnect the ECM connector.
- Disconnect the combination meter connector.
- Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition A35-36 (W) or C50-20 (CHK) - Body ground Always 10 kΩ or higher
NG → REPAIR OR REPLACE HARNESS OR CONNECTOR
OK → See step 10
- CHECK THAT MIL IS ILLUMINATED
- Check if the MIL is illuminated when the ignition switch is turned to ON.
OK
MIL is illuminated.
NG → See step 6
OK → END
- Check if the MIL is illuminated when the ignition switch is turned to ON.
- CHECK THAT ENGINE STARTS
- Turn the ignition switch to ON.
- Start the engine.RESULT
Result Proceed to Engine starts A Engine does not start* B HINT:
*: The Techstream cannot communicate with the ECM.
B → See step 12
A: Go to next step
- CHECK HARNESS AND CONNECTOR (COMBINATION METER - ECM)
- Disconnect the ECM connector.
- Disconnect the combination meter connector.
- Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition A35-36 (W) - C50-20 (CHK) Always Below 1 Ω
NG → REPAIR OR REPLACE HARNESS OR CONNECTOR
OK → See step 11
