| Step | Check | Yes | No |
|---|---|---|---|
1 CHECK VDCCM & H/U GROUND CIRCUIT (CHECK FOR OPEN CIRCUIT).
|
Is the resistance less than 10 Ω? | Go to step 2 . | Repair the VDCCM & H/U ground harness. |
| 2 CHECK POOR CONTACT OF CONNECTORS. | Is there poor contact of the connector between the battery, ignition switch and VDCCM & H/U? | Repair the connector. | Go to step 3. |
| 3 CHECK CAUSE OF SIGNAL NOISE. | Are the radio wave devices and electronic components installed correctly? | Go to step 4. | Install the radio wave devices and electronic components properly. |
| 4 CHECK CAUSE OF SIGNAL NOISE. | Is there a noise source (such as an antenna) installed near the sensor harness and VDCCM? | Install the noise sources apart from sensor harness and VDCCM. | Go to step 5. |
5 CHECK VDCCM & H/U.
|
Is the same DTC displayed? | Replace the VDCCM & H/U. <Ref. to VDC CONTROL MODULE AND HYDRAULIC CONTROL UNIT (VDCCM & H/U) .> | Go to step 6. |
| 6 CHECK DETECTION OF OTHER DTCS FOR VDC. <Ref. to READ DIAGNOSTIC TROUBLE CODE (DTC) .> |
Is any other DTC displayed? | Perform the diagnosis according to DTC. <Ref. to LIST OF DIAGNOSTIC TROUBLE CODE (DTC) .> | Currently, it is normal. There may have been a temporary poor contact in the harness and connector or a temporary noise interference. |
