Hyundai Venue: Hydraulic System / 26 Brake Control Solenoid Valve (26/B_VFS). Repair procedures
| • |
Refer to the DTC manual for the check procedure.
|
|
| • |
When the solenoid valve Diagnostic Trouble Codes (DTC) is on,
perform the following procedure to replace it.
|
| • |
Automatic transaxle is composed of delicate components. Be careful
not to cause any damage on the component in the course of assembly
and disassembly.
|
| • |
Maintain clean condition so that foreign substance does not
get into the automatic transaxle.
|
| • |
Use a coated apron, latex gloves, and stainless tray to prevent
foreign substance from getting into the transaxle.
|
| • |
Automatic transaxle fluid (ATF) can be reused. Collect it using
a clean 10-liter beaker.
|
|
| 1. |
Turn ignition switch OFF and disconnect the negative (-) battery cable.
|
| 2. |
Remove the air cleaner and air duct.
| (1) |
Remove the air duct (A).
|
| (2) |
Disconnect the breather hose (B) and air intake hose (C).
|
| (3) |
Remove the air cleaner assembly (D).
|
Tightening torque :
Hose clamp bolt (C):
2.9 - 4.9 N.m (0.3 - 0.5 kgf.m, 2.1 - 3.6 lb-ft)
Air cleaner assembly bolts (D) :
3.9 - 5.9 N.m (0.4 - 0.6 kgf.m, 2.9 - 4.3 Ib-ft)
|
|
|
| 3. |
Discharge the automatic transaxle fluid (ATF).
(Refer to Automatic Transaxle Syatem - "Automatic Transaxle Fluid (ATF)")
|
| 4. |
Disconnect the wiring fixing clip (A).
|
| 5. |
Disconnect the air bleeder hose (B).
|
| 6. |
Disconnect the ATF cooler hose (A).
| •
|
Be careful not to cause any damage on the hose when
tightening the clamp.
|
| •
|
Mount the clamp tightening part in the designated direction
so that interference does not occur with the adjacent
parts.
|
| •
|
After connecting the hose, check for oil leakage on
the connecting part while the engine is on.
|
|
|
| 7. |
Unscrew the bolts and remove the valve body cover (A).
|
Tightening torque :
11.8 - 13.7 N.m (1.2 - 1.4 kgf.m, 8.7 - 10.1 lb-ft)
|
| •
|
When re-mounting the valve body cover, replace the gasket
with a new one.
|
| •
|
After mounting the valve body cover, check for oil leakage
on the connecting part while the engine is on.
|
|
|
| 8. |
Unscrew the bolts and disconnect the solenoid valve connector (A).
|
Tightening torque :
9.8 - 11.8 N.m (1.0 - 1.2 kgf.m, 7.2 - 8.7 lb - ft)
|
|
| 9. |
Remove the support bracket (A).
|
Tightening torque :
9.8-11.8N.m (1.0 - 1.2 kgf.m, 7.2 - 8.7 lb-ft)
|
|
| 10. |
Remove the roller (A) and bolt (B).
|
Tightening torque :
9.8 - 11.8N.m (1.0 - 1.2 kgf.m, 7.2 - 8.7 lb-ft)
|
|
| 11. |
Remove the 26 brake control solenoid valve (A).
|
| • |
Note the value carefully and check the value again before assembly.
|
| • |
Inputting an invalid value (A) may cause the abnormal shifting
shock while TCM learning.
|
|
| 1. |
To install, reverse the removal procedure.
|
| 2. |
Inject the automatic transaxle oil and inspect the oil level.
(Refer to Automatic Transaxle System - "Automatic Transaxle Fluid (ATF)")
|
| 3. |
Clear the diagnostic trouble codes (DTC) using the diagnostic tool.
| •
|
Even though disconnecting the battery negative terminal,
the DTCs will not be cleared. So, be sure to clear the
DTCs using the diagnostic tool.
|
|
|
| 4. |
Reset the automatic transaxle adaptive values using the diagnostic tool.
|
| 5. |
Input the oil pressure characteristics using the diagnostic tool.
| (1) |
Select ‘Oil-pressure Characteristics (Solenoid Valve Replacement)’
in the S/W Management.
|
| (2) |
Select the replaced solenoid valve.
|
| (3) |
Check the code marked on the solenoid valve.
(※ Caution : Check the code at first before replacement)
|
| (4) |
If the code is inputted 2 times correctly, the procedure is
completed.
|
|
| 6. |
In order to prevent start delay and gear shift shock during acceleration
and start, perform TCM learning after replacing the solenoid valve.
