3. When the BCM finishes assigning each tire ID, the BCM flashes the hazard warning lamps and sends
flashing indicator status by CAN according to the following time chart.
4. After completing wake up of all transmitters, make sure low tire pressure warning lamp goes out.
CONSULT-II Function (BCM)INFOID:0000000003532699
CONSULT-II can display each diagnostic item using the diagnostic test modes shown following.
Self-DiagnosisINFOID:0000000003532700
DESCRIPTION
During driving, the low tire pressure warning system receives the signal transmitted from the transmitter
installed in each wheel, and turns on the low tire pressure warning lamp when the tire pressure becomes low.
The control unit (BCM) for this system has pressure judgement and self-diagnosis functions.
FUNCTION
When the low tire pressure warning system detects low inflation pressure or an internal malfunction, the low
tire pressure warning lamp in the combination meter comes on. The malfunction location is indicated by the
low tire pressure warning lamp flashing and the buzzer sounding.

How to Perform Trouble Diagnosis for Quick and Accurate RepairINFOID:0000000003532701
INTRODUCTION
• Before troubleshooting, verify customer complaints.
• If a vehicle malfunction is difficult to reproduce, harnesses, harness connectors or terminals may be mal-
functioning. Hold and shake these parts to make sure they are securely connected.
• When using a circuit tester to measure voltage or resistance of each circuit, be careful not to damage or
deform connector terminals.
