ON-BOARD DIAGNOSTIC SYSTEM FUNCTION (TIRE PRESSURE MONITORING SYSTEM)


id020200100200


Malfunction Detection Function

•  The malfunction detection function detects malfunctions in the input/output signal system of the instrument cluster based on abnormal signals from the wheel units when the ignition is at the ON position or driving the vehicle.
•  The TPMS warning light illuminates for approx. 3.0 s when the ignition is switched to the ON to inspect for open circuits in the light.

Malfunction Indication Function

•  When the malfunction detection function detects a malfunction, the TPMS warning light illuminates to advise the driver. Using the external tester communication function, DTCs can be output to the DLC-2 via the CAN communication line. At the same time, malfunction detection results are sent to the memory functions.

Memory Function

•  The memory function stores DTCs for malfunctions in input/output signal systems. With this function, once a DTC is stored it is not cleared after the ignition has been switched to off, even if the malfunctioning signal system has returned to normal.
•  Since instrument cluster has a built-in non-volatile memory, DTCs are not cleared even if the battery is removed. Therefore, it is necessary to clear the memory after performing repairs. Refer to the Workshop Manual for the DTC clearing procedure.
