DESCRIPTION
During driving, the low tire pressure warning system receives the signal transmitted from the transmitter
installed in each wheel, and gives alarms when the tire pressure becomes low. The control unit of this system
has pressure judgement and trouble diagnosis functions.
FUNCTION
When the low tire pressure warning system detects low inflation pressure or another unusual symptom, the
warning lamps in the combination meter comes on. To start the self-diagnostic results mode, ground the self-
diagnostic (check) terminal. The malfunction location is indicated by the warning lamp flashing and the buzzer
sounds.
CONSULT-II
CONSULT-II Main Function
In a diagnosis function (main function), there are “WORK SUPPORT”, “SELF-DIAGNOSTIC RESULTS”,
“DATA MONITOR”, “CAN DIAG SUPPORT MNTR”.
