Purpose
The tire pressure warning alarm warns the user that a tire pressure has decreased or notifies the user that the tire pressure warning alarm has been reset.
Function
If the instrument cluster receives a tire pressure warning alarm request signal sent from the DSC HU/CM via the CAN signal, the tire pressure warning alarm is sounded.
The tire pressure warning alarm sound pattern is as follows: For the conditions in which each alarm pattern sounds, refer to TIRE PRESSURE MONITORING SYSTEM (TPMS).
Tire pressure monitoring system operating
Tire pressure monitoring system initialization
Construction
The tire pressure warning alarm sounds using the buzzer built into the instrument cluster.
Operation
1. The instrument cluster receives (1) the tire pressure warning alarm request signal from the DSC HU/CM.
2. The instrument cluster microcomputer turns the transistor on (2) based on the tire pressure warning alarm request signal.
3. When the transistor turns on, the ground circuit of the alarm is established and the alarm sounds (3).
Fail-safe
Function not equipped.
Global Positioning System (Gps) Antenna
Purpose, Function
The GPS antenna receives signals sent from GPS satellites and sends them
to the car navigation unit.
NOTE:
GPS (Global Positioning System) was developed by the Pentagon (U.S.A.) as
an object locating system using satellites. The GPS antenna receives signa ...
Solar Radiation Sensor Inspection [Full Auto Air Conditioner]
1. Shine a fluorescent light or expose the solar radiation sensor to natural
sunlight.
2. Connect the positive (+) lead to terminals B, C and negative (-) lead to terminal
A of the solar radiation sensor, and verify that the voltage value is output.
If the voltage is 0 V, replace ...
Awd Control Module Inspection
NOTE:
AWD CM terminal voltage can vary depending on measuring conditions and vehicle
aging, resulting in misdiagnosis. Therefore, it is necessary to perform an overall
inspection of the input/output systems and AWD CM to determine which part is
malfunctioning.
With the AWD C ...
