ACTION |
| 1 |
VERIFY PCM DTC
|
Yes |
Go to the applicable DTC inspection.
(See DTC TABLE [PCM (SKYACTIV-G 2.0, SKYACTIV-G 2.5)]
.) |
| No |
Go to the next step. |
| 2 |
INSPECT COMMUNICATION LINE BETWEEN PCM AND INSTRUMENT CLUSTER
- Inspect for a short or open circuit between the following terminals:
- Instrument cluster terminal B-Front body control module (FBCM) terminal 2K
- Instrument cluster terminal D-Front body control module (FBCM) terminal 2I
- Front body control module (FBCM) terminal 2P-PCM terminal 2AK
- Front body control module (FBCM) terminal 2N-PCM terminal 2AL
- Is the wiring harness normal?
|
Yes |
Inspect the instrument cluster.
(See INSTRUMENT CLUSTER INSPECTION
.)
- If there is any malfunction:
|
| No |
Refer to the wiring diagram and verify whether or not there is a common connector between the following terminals:
- Instrument cluster terminal B-Front body control module (FBCM) terminal 2K
- Instrument cluster terminal D-Front body control module (FBCM) terminal 2I
- Front body control module (FBCM) terminal 2P-PCM terminal 2AK
- Front body control module (FBCM) terminal 2N-PCM terminal 2AL
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 or open circuit.
- Repair or replace the malfunctioning part.
If there is no common connector:
- Repair or replace the wiring harness which has a short to ground or open circuit.
Go to the next step. |
| 3 |
Verify the test results.
- If normal, return to the diagnostic index to service any additional symptoms. (See SYMPTOM DIAGNOSTIC INDEX .)
- If the malfunction remains, inspect the related Service Bulletins and/or On-line Repair Information and perform repair or diagnosis.
- If the vehicle is repaired, troubleshooting is completed.
- If the vehicle is not repaired or additional diagnostic information is not available, reprogram the PCM if a later calibration is available. Retest.
