Hyundai i-30: Dual Clutch Transmission Control System / Inhibitor Switch
Description and operation
| • |
The inhibitor switch is installed on top of transmission, and is connected
to the shift lever through shift cable.
|
| • |
Inhibitor switch signals (S1, S2, S3, S4) are transmitted to the TCM
according to the driver's shift lever control.

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)
|

|
Repair procedures
| •
|
Thoroughly check connectors for looseness, poor connection,
bending, corrosion, contamination, deterioration, or damage.
|
|
Inspection flow
Items to check
|
2. |
Inspect whether N setting matches.
| –
|
Adjust N setting (refer to automatic transmission system - "inhibitor
switch")
|
|
|
3. |
Inspect shift cable separation.
| –
|
Adjust shift cable separation (refer to automatic transmission
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 inhibitor 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 inhibitor 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. |

Other information:
The Parking Distance Warning
(Reverse/Forward) system assists
the driver during movement of the
vehicle by chiming if any object is
sensed within the distance of 100 cm
(39 inches) in front and 120 cm (47
inches) behind the vehicle.
This system is a supplemental system
that senses objects within the
range and location of the sensors, it
cannot detect objects in other areas
where sensors are not installed...
Removal
•
In case of bad quality or poor focus, be sure to check the camera
lense surface condition and foreign materials...

If your vehicle is equipped with a
sunroof, you can slide or tilt your
sunroof with the sunroof control lever
located on the overhead console.
The ignition switch must be in the ON
position before you can open or
close the sunroof.
The sunroof can be operated for
approximately 30 seconds after the
ignition key is removed or turned to
the ACC or LOCK(or OFF) position.
However, if the front door is opened,
the sunroof cannot be operated even
within 30 seconds.
