BCS-34 < FUNCTION DIAGNOSIS > [BCM] DIAGNOSIS SYSTEM (BCM) ACTIVE TEST AIR PRESSURE MONITOR INFOID:0000000004218977 DESCRIPTION During driving, the TPMS receives the signal transmitted from the transmitter installed in each wheel, when the tire pressure becomes low. The control unit (BCM) of this system has pressure judgment and trouble diag- nosis functions. When the TPMS detects low inflation pressure or another unusual symptom, the warning lamps in the combi- nation meter comes on. SELF DIAGNOSTIC PROCEDURE (WITH CONSULT-III) With CONSULT-III • Touch “SELF-DIAG RESULTS” display shows malfunction experienced since the last erasing operation. SELF DIAGNOSTIC PROCEDURE (WITHOUT CONSULT-III) Without CONSULT-III To start the self-diagnostic results mode, ground terminal of the tire pressure warning check connector. The malfunction location is indicated by the warning lamp flashing. NOTE: When the low tire warning lamp flashes 5 Hz and continues repeating it, the system is normal. Monitor item [UNIT] Description PUSH SW Displays the status of the push-button ignition switch judged by BCM.
