Hyundai Genesis (DH): IMS(Integrated Memory System) / Description and Operation
The optimal seat position set by the driver is memorized into
the power seat unit by using IMS switch. In case of the position
change, the seat can restore its preset position by IMS switch.
It has safety functions of restoring process prohibition during driving and of emergency stop of the linked motion.
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 seat 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 DDM during IMS switch controlling. |
|
| 3. |
Motion linked to getting on/off
| (1) |
This function links 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. |
|
Reproducing motion
| 1. |
If the reproduction CAN data is received from DDM, the buzzer
is issued one time and the seat is automatically moved to the memorized
position. |
| 2. |
The CAN data not memorized does not perform reproduction function. |
| 3. |
If CAN data is newly received during previous data reproduction, the final data takes precedence. |
| 4. |
If the reproduction CAN data is received by pressing button 1 or 2 during reproduction, the seat stops the reproduction process. |
| 5. |
If the memorized CAN data is received by pressing SET button during reproduction, the seat stops the reproduction process.
|
Press the SET button once more to store the position of stop. |
|
| 6. |
Automatically stop when remart switch is OFF during reproduction. |
| 7. |
Do not operate the motor when the difference between the
memorized position for reproduction and current position is less than 4
pulses. |
Conditions for prohibiting the reproduction
In case any of the following conditions is met, the reproduction is prohibited and the controlling stops during reproduction.
| 1. |
IGN2 OFF (Excluding within 30 seconds after door opening or closing.) |
| 2. |
Higher than 3km/h of vehicle speed |
| 3. |
When the switch is controlled manually |
| 4. |

Description
An in-car air temperature sensor is located in the crash pad lower panel.
The sensor contains a thermistor which measures the
temperature of the cabin. The signal determined by the resistance value
which changes in accordance with perceived inside temperature, is
delivered to the heater control unit and according to this signa
Inspection
1.
Connect the battery voltage and check the blower motor rotation.
2.
If the blower motor does not operate well, replace it with a genuine blower motor check for proper operation.
3.
Replace the blower motor if it is proved that there is a problem with it.
