RECORD VEHICLE STATUS AT TIME OF DTC DETECTION TO UTILIZE WITH REPEATABILITY VERIFICATION
NOTE:
- Recording can be facilitated using the screen capture function of the PC.
- Record the FREEZE FRAME DATA/snapshot data on the repair order.
|
- |
Go to the next step. |
| 2 |
VERIFY RELATED REPAIR INFORMATION AVAILABILITY
- Verify related Service Bulletins and/or on-line repair information availability.
- Is any related repair information available?
|
Yes |
Perform repair or diagnosis according to the available repair information.
- If the vehicle is not repaired, go to the next step.
|
| No |
Go to the next step. |
| 3 |
INSPECT ECT SENSOR NO. 2 CONNECTOR CONDITION
- Switch the ignition off.
- Disconnect the ECT sensor No. 2 connector.
- Inspect for poor connection (such as damaged/pulled-out pins, corrosion).
- Is there any malfunction?
|
Yes |
Repair or replace the connector and/or terminals, then go to Step 8. |
| No |
Go to the next step. |
| 4 |
DETERMINE IF ECT SENSOR NO. 2 OR WIRING HARNESS MALFUNCTION
- Reconnect all disconnected connectors.
- Access the ECT2_V PID using the M-MDS. (See ON-BOARD DIAGNOSTIC TEST
.)
- Verify the ECT2_V PID value when disconnecting the ECT sensor No. 2 connector.
- Does the ECT2_V PID value change?
|
Yes |
Replace the ECT sensor No. 2, then go to Step 8.
(See ENGINE COOLANT TEMPERATURE (ECT) SENSOR REMOVAL/INSTALLATION
.) |
| No |
Go to the next step. |
| 5 |
INSPECT PCM CONNECTOR CONDITION
- Switch the ignition off.
- Disconnect the PCM connector.
- Inspect for poor connection (such as damaged/pulled-out pins, corrosion).
- Is there any malfunction?
|
Yes |
Repair or replace the connector and/or terminals, then go to Step 8. |
| No |
Go to the next step. |
| 6 |
INSPECT ECT SENSOR NO. 2 SIGNAL CIRCUIT FOR SHORT TO GROUND
- Verify that the PCM connector is disconnected.
- Disconnect the ECT sensor No. 2 connector.
- Inspect for continuity between ECT sensor No. 2 terminal A (wiring harness-side) and body ground.
- Is there continuity?
|
Yes |
Refer to the wiring diagram and verify whether or not there is a common connector between ECT sensor No. 2 terminal A and PCM terminal 2F.
If there is a common connector:
- Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for a short to ground.
- Repair or replace the malfunctioning part.
If there is no common connector:
- Repair or replace the wiring harness which has a short to ground.
Go to Step 8. |
| No |
Go to the next step. |
| 7 |
INSPECT ECT SENSOR NO. 2 SIGNAL CIRCUIT AND GROUND CIRCUIT FOR SHORT TO EACH OTHER
- Verify that the ECT sensor No. 2 and PCM connectors are disconnected.
- Inspect for continuity between ECT sensor No. 2 terminals A and B (wiring harness-side).
- Is there continuity?
|
Yes |
Refer to the wiring diagram and verify whether or not there is a common connector between the following terminals:
- ECT sensor No. 2 terminal A-PCM terminal 2F
- ECT sensor No. 2 terminal B-PCM terminal 2AJ
If there is a common connector:
- Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for a short to each other.
- Repair or replace the malfunctioning part.
If there is no common connector:
- Repair or replace the wiring harness which has a short to each other.
Go to the next step. |
| No |
Go to the next step. |

VERIFY DTC TROUBLESHOOTING COMPLETED
- Always reconnect all disconnected connectors.
- Clear the DTC from the PCM memory using the M-MDS. (See AFTER REPAIR PROCEDURE
.)
- Perform the KOEO or KOER self test. (See KOEO/KOER SELF TEST
.)
- Is the PENDING CODE for this DTC present?
|
Yes |
Repeat the inspection from Step 1.
Go to the next step. |
| No |
Go to the next step. |
| 9 |
VERIFY AFTER REPAIR PROCEDURE
|
Yes |
Go to the applicable DTC inspection.
