Items to Check and Measures
|
| Shift lever not operating Gear not marked on cluster Shock occurs while shifting lever Warning lamp ON Engine OFF while vehicle is parked | Inhibitor switch circuit abnormal Inhibitor switch function abnormal | Check the inspection FLOW and replace the inhibitor switch |
| Inhibitor switch "N" setting faulty | Adjust "N" setting using "N" setting jig (Refer to Dual Clutch Transmission Control System - "Inhibitor Switch") | |
| Shift cable separation faulty | Adjust shift cable separation (Refer to Dual Clutch Transmission Control System - "Inhibitor Switch") | |
| Poor ground condition on reversing light circuit | Check the ground condition on reversing light and retighten it | |
| Inhibitor switch vehicle side circuit abnormal | Check the connection of junction box power terminal, fuse (TCU) terminal and replace the junction box or adjust the gap | |
| Check inside the inhibitor switch connector for foreign substance and whether terminal is bent | ||
| Poor ground condition on inhibitor switch wire | Check the ground condition of wire and retighten it | |
| Poor inhibitor unit (disconnection/short-circuit) | Replace inhibitor switch (refer to inhibitor switch inspection) |

Inspection • Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage.
DescriptionThe A/C Pressure Transducer (APT) converts the pressure value of high pressure line into voltage value after measuring it. By converted voltage value, engine ECU controls the cooling fan by operating it high speed or low speed. Engine ECU stops the operation of the compressor when the temperature of refrigerant line is very high or very
Inspection1.Turn the ignition switch OFF. 2.Disconnect the auto defogging connector. 3.Verify that the auto defogging actuator operates to the open position when connecting 12V to terminal 3 and grounding terminal 4. Verify that the auto defogging actuator operates to the close position when connected in reverse.
