Hyundai Santa Cruz: Dual Clutch Control System / Position Switch

- Description

• Component Location : Dual Clutch Transmission assembly

• Function

– - The position switch mounted on the upper of transmission and connected with shifter lever.

– Check whether the vehicle can be driven forward/backward while engine is running.

– It controls the the shift stage by transmitting the PWM signal value of the position switch to the TCM according to the P, R, N, D operation of the shift lever.

1. Position switch
2. Manual control lever

Signal code table

• Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage.

1.Inspect DTC code.

2.Inspect whether N setting matches.

– Adjust N setting (Refer to Dual Clutch Transmission Control System - "Position Switch").

3.Inspect shift cable separation.

– Adjust shift cable separation (Refer to Dual Clutch Transmission Control System - "Shift Cable").

4.Inspect whether connector is connected.

– Inspect connector thoroughly for looseness, poor connection, bending, corrosion, contamination, deformation, or damage.

– Turn ignition key "ON" and engine "OFF" and measure the power supplied to Position switch circuit and voltage between ground.

Specification: approx. 12 V

– Fix the pin wiring when connector pin wiring is faulty (refer to ETM - "wiring repair").

5.Inspect ground condition on reversing light circuit.

– Check the ground location of reversing light (refer to ETM - "harness location map").

– Reattach reversing light if ground condition is faulty.

6.Inspect wiring connection on junction box power terminal and fuse lamp.

– Check whether fuse holder is separated and holder is holding the fuse tight.

– Attach tester fuse to check if it is connected appropriately.

– Check whether fuse capacity is appropriate for each circuit.

– Check if fuse is damaged.

– Check pulling of fuse fixing wiring, inflow of foreign substance, and arrangement condition of terminal.

– Relocate the terminal that has been pulled and inspect using the method explained above.

– When problem is not solved, refer to the circuit diagram wiring repair instructions to fix or replace the terminal.

7.Inspect position switch signal.

– Turn ignition key "ON" and engine "OFF".

– Measure the voltage between each terminal and chassis ground when shifting lever to "P, R, N, D" range.

Specified value: refer to specification "signal code" table

1.Move the shift lever to "N".

2.Turn ignition OFF switch and the disconnect the negative (-) battery cable.

3.Remove the air cleaner assembly and air duct.(Refer to Engine Mechanical System - "Air cleaner")

4.Remove the ECM.(Refer to Engine Control / Fuel System - "Engine Control Module (ECM)")

5.Remove the battery and battery tray.(Refer to Engine Electrical System - "Battery")

6.Disconnect the position switch connector (A).

7.Loosen the shift cable mounting nut (A).

8.Remove the manual control lever (A) after loosening the mounting nut.

9.Loosen the bolts and then removing the position switch (A).

1.Check that the shift lever is placed in the "N" position.

2.Install the position switch (A) and then lightly tighten the position switch mounting bolts.

3.Align the hole in the manual control lever (A) with the "N" position hole (B) of the position switch and then tighten the nut (D) and washer (C) with specified torque.

Tightening torque:17.6 - 24.5 N.m (1.8 - 2.5 kgf.m, 13.0 - 18.0 lb-ft)

4.Insert the position switch neutral fixed pin (SST No..: 09480-A3800) (A) for "N" position hole.

5.Tighten the position switch mounting bolts (A) with specified torque.

Tightening torque:9.8 - 11.7 N.m (1.0 - 1.2 kgf.m, 7.2 - 8.6 lb-ft)

6.Remove the position switch neutral fixed pin (SST No.:09480-A3800) (A) from the hole.

7.Push shift cable (A) lightly to "F" direction shown to eliminate free play of shift cable.Tighten the nut (B) with the specified torque.

Tightening torque:9.8 - 14.7 N.m (1.0 - 1.4 kgf.m, 7.2 - 10.8 lb-ft)

8.Connect the position switch connector (A).

9.Remove the battery and battery tray.(Refer to Engine Electrical System - "Battery")

10.Remove the ECM.(Refer to Engine Control / Fuel System - "Engine Control Module (ECM)")

11.Remove the air cleaner assembly and air duct.(Refer to Engine Mechanical System - "Air cleaner")

• Check that operating surely at each range of the position switch corresponding to each position of shift lever.
