IMS(Integrated Memory System) is a system which can memorize the position of power seat(PSM), tilt/telescope handle(SCM), side mirror(DDM/ADM) by position sensor and restores them to a previous position. (Memory function is not allowed during driving for safety reason)
SCM sets this code when amount of change of the tilt motor position sensor is less than 8edge (4pulse) for 1sec. This means that tilt motor/sensor stuck due to open or short in circuit or external cause (compulsive restriction)
Item | Detecting Condition | Possible Cause |
DTC Strategy |
•
Monitoring the motor's revolution by checking the pulse output of HALL sensor in the motor |
•
Open in the Tilt motor circuit
•
Open in the Tilt motor sensor circuit
•
Faulty Tilt motor/ sensor |
Enable Conditions |
•
When the motor is running | |
Threshold Value |
•
During the Tilt motor is operated, when the pulse input is less than 4 pulses within 1 second. | |
Diagnostic Time |
•
Immediately | |
DTC Erasing Time |
•
DTC is erased immediately after trouble fixed |
