Hyundai Genesis (DH): IMS(Integrated Memory System) / Tilt & Telescope Control (SCM) Description and Operation
The Tilt & Telescope operation function in SCM contains of the following function.
| 1. |
Manual control with direction switches (Tilt Up/Down, Telescope Forward/Backward). |
| 2. |
Playback with position switches (P1 and P2 switches). |
| 3. |
Memory with position switches (P1 and P2 switches). |
| 4. |
Easy Access operation control according to the IGN SW SCM =
Key Off>Key Off exception or IGN SW SCM=Key Off exception > Key Off |
| 5. |
Easy Entry Position Renewal |
| 8. |
Notice (Manual, Memory Playback, Easy Access operation) |
The changed position of the seat by memorizing into the power
seat unit with IMS switch controlling the optimal seat position set by
the driver can be restored with the IMS switch.
It has the function of prohibiting the restoring action during driving and emergent stopping the linked motion for safety. .
The main functions are as follows.
| 1. |
Manual operation: Motor control with the seat manual switch
| (1) |
The position of the seat is changed by operating the motor
when the signal is input with manual switch for the seat (Slide,
recline, front tilt, rear height adjusting cushion extension) |
|
| 2. |
Memory function : Available for memorizing/reproducing the data for two persons with IMS switch.
| (1) |
The memorized motion for the optimal seal position set by the
driver based on the CAN data with ?DDM > IMS module?with IMS
switch. |
| (2) |
Reproduction by the CAN data received from DDN during IMS switch controlling. |
|
| 3. |
Motion linked for getting on/off
| (1) |
Function of getting on/off linked motion depending on the state of ON/OFF the engine |
| (2) |
Use of IMS CAN data communcation |
| (3) |
Condition for operating getting on : When the electric power is in ACC |
|
Behavior For Normal State
Manual Control With Direction Switches
| 1. |
Tilt & Telescope operation is carried out in SCM
according to user handling of direction switches when the following
conditions are satisfied.
| A. |
Only one of direction switches is pressed ON (Tilt Up/Down , Telescope Forward/Backward). |
|
| 2. |
Manual has priority although self-diagnosis actuator operation order is received (actuator operation ignorance) |
Soft Limit Setting By Manual Switches
| 1. |
The LIMIT must be renewal in all range by MANUAL operation at the first setting of LIMIT |
| 2. |
If the error is occurred during operation, after saving the
ERROR DATA in EEPROM, easy access position is deleted and only SOFT
LIMIT to going direction is deleted. |
| 3. |
The LIMIT must be reset in all range and in easy access (get out) after recovery form error. |
| 4. |
The SOFT LIMIT is presented |
Removal
1.
Disconnect the negative (-) battery terminal.
2.
Remove the driver's door trim.
(Refer to Body - "Front Door Trim")
3.
Remove the memory power seat switch connector (A).

Inspection
1.
Turn the ignition switch OFF.
2.
Disconnect the mode control actuator connector.
3.
Verify that the mode control actuator operates to the defrost mode when connecting 12V to terminal 3 and grounding terminal 4.
Verify that the mode control actuator operates to the vent mode when connected in reverse.
