Hyundai Elantra: Automatic Transaxle Control System / Inhibitor Switch Repair procedures
| Inspection flow of the inhibitor switch |
Items to check
| 2. |
Inspect whether N setting matches.
| A. |
Adjust N setting (refer to automatic transmission system - "inhibitor switch") |
|
| 3. |
Inspect shift cable separation.
| A. |
Adjust shift cable separation (refer to automatic transmission system - "shift cable") |
|
| 4. |
Inspect whether connector is connected.
| A. |
Inspect connector thoroughly for looseness, poor connection, bending, corrosion, contamination, deformation, or damage. |
| B. |
Turn ignition key "ON" and engine "OFF" and measure the power supplied to inhibitor switch circuit and voltage between ground.
Specification: approx. 12 V
|
|
| C. |
Fix the pin wiring when connector pin wiring is faulty.
(refer to ETM - "wiring repair"). |
|
| 5. |
Inspect ground condition on reversing light circuit.
| A. |
Check the ground location of reversing light (refer to ETM - "harness location map"). |
| B. |
Reattach reversing light if ground condition is faulty. |
|
| 6. |
Inspect wiring connection on junction box power terminal and fuse lamp.
| A. |
Check whether fuse holder is separated and holder is holding the fuse tight. 
|
| B. |
Attach tester fuse to check if it is connected appropriately. 
|
| C. |
Check whether fuse capacity is appropriate for each circuit. |
| D. |
Check if fuse is damaged. |
| E. |
Check pulling of fuse fixing wiring, inflow of foreign substance, and arrangement condition of terminal. |
| F. |
Relocate the terminal that has been pulled and inspect using the method explained above. |
| G. |
When problem is not solved, refer to the circuit diagram wiring repair instructions to fix or replace the terminal. |
|
| 7. |
Inspect inhibitor switch signal.
| A. |
Turn ignition key "ON" and engine "OFF". |
| B. |
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. |
Make sure vehicle does not roll before setting shift lever to "N" position. |
| 2. |
Disconnect the negative (-) battery cable. |
| 3. |
Remove the air cleaner assembly and air duct.
(Refer to Engine Mechanical System - "Air cleaner") |
| 4. |
Remove the battery and battery tray.
(Refer to Engine Electrical System - "Battery") |
| 5. |
Disconnect the inhibitor switch connector (A). |
| 6. |
Remove the shift cable mounting nut (B). 
|
| 7. |
Remove the manual control lever (B) and the washer after removing a nut (A). 
|
| 8. |
Remove the inhibitor switch(A) after removing the bolts (2ea). 
|
| 1. |
Check that the shift lever is placed in the "N" position. |
| 2. |
Lightly tighten the bolts(A) after installing the inhibitor switch(B). 
|
| 3. |
Lightly tighten the nut(A) after installing the manual control lever(B). 
|
| 4. |
Align the hole (A) in the manual control lever with the "N"
position hole (B) of the inhibitor switch and then insert the inhibitor
switch guide pin (SST No.:09480-A3800). 
|
| 5. |
Tighten the nut (A) and bolts (B) with the specified torque.
Tightening torque :
A : 17.7 ~ 24.5 N.m (1.8 ~ 2.5 kgf.m, 13.0 ~ 18.1 lb-ft)
B : 9.8 ~ 11.8 N.m (1.0 ~ 1.2 kgf.m, 7.2 ~ 8.7 lb-ft)
|
|
| 6. |
Lightly tighten the nut(B) after connected the shift cable(C) in the manual control lever(D). |
| 7. |
Push shift cable(C) lightly to "F" direction shown to eliminate free play of shift cable. |
| 8. |
Tighten the nut(B) with the specified torque.
Tightening torque :
9.8 ~ 13.7 N.m (1.0 ~ 1.4 kgf.m, 7.2 ~ 10.1 lb-ft)
|
|
| 9. |
Remove the inhibitor switch guide pin (SST No.:09480-A3800) from the hole. |
| 10. |
Connect the inhibitor switch connector(A). 
|
| 11. |
Install the battery and battery tray.
(Refer to Engine Electrical System - "Battery") |
| 12. |
Install the air cleaner assembly and air duct.
(Refer to Engine Mechanical System - "Air cleaner") |
| 13. |
Connect the battery negative (-) cable. |
| 14. |
Check that operating surely at each range of the inhibitor switch corresponding to each position of shift lever. |
