1. DESCRIPTION OF SYSTEM
(a) A tire pressure warning valve and transmitter is equipped with a tire pressure sensor and a transmitter and is installed in a tire wheel assembly.
The sensor measures the tire pressure. The measured value and transmitter ID are transmitted to the tire pressure warning antenna and receiver on the body as radio waves and then sent to the tire pressure warning ECU from the tire pressure warning antenna and receiver. If the transmitter ID has already been registered, the ECU compares the measured air pressure value with the specified value. When the value is less than the specified value registered in the tire pressure warning ECU, the warning light on the combination meter comes on.
2. INITIAL CHECK
(a) The tire pressure warning light turns on for 3 seconds after the ignition switch ON and then goes off.
HINT:
If the warning light does not turn on for 3 seconds,
troubleshoot the tire pressure warning light circuit.
3. WHEN TIRE PRESSURE WARNING LIGHT IS LIT
(a) When the tire pressure warning light does not go off, or when it comes on during driving, check tire pressure. If the tire pressure warning light comes on within several hours after adjusting the tire pressure, the tire may have a slow air leak.
(b) Under the following conditions, the system may not function properly.
(c) After removing and installing the ECU or a sensor, check for a diagnostic trouble code and verify that it is a normal code.
4. FUNCTION OF COMPONENTS
Components | Function |
Tire pressure warning valve and transmitter | Combined as a single unit with a disc wheel air valve, it measures
tire pressure and
temperature and transmits an ID number for measurement value and
identification.
Built-in the battery. |
Tire pressure warning antenna and receiver | Receives and transmits a necessary signal from the transmitter to the tire pressure warning ECU. |
Tire pressure warning ECU | Receives a signal from the receiver and identifies it as vehicle's own signal. If the measured value is equal to or lower than the specified value, it transmits a signal so that the tire pressure warning light on the combination meter comes on. |
Tire pressure warning light | Located in the combination meter, it informs the driver of lowered tire air pressure and system failure. |
Tire pressure warning reset switch | Enters the initialization mode for the change of the standard pressure |
5. TIRE PRESSURE WARNING RESET SWITCH
Therefore, the dealer must set the warning threshold to the proper value in order to comply with the local regulations.
Power Slide Door RH does not Operate When Using Inside / Outside
Handle
DESCRIPTION
The inside / outside handles have the ability to control operation
of the power slide door. Pulling either
handle transmits a request signal to the power slide door ECU RH, which then
commands the power
slide door control motor and clutch to open / close the power sli ...
