Tire Pressure Warning Light Circuit
DESCRIPTION
If the tire pressure warning ECU and receiver detects any problems, the tire
pressure warning light blinks for 1 minute then illuminates, and tire pressure monitoring
is disabled at t
Tire Position Not Identified
DESCRIPTION
The tire pressure warning ECU and receiver identifies the tire position for each
tire pressure warning valve and transmitter according to the wheel speed signals
from the skid control

MONITOR DESCRIPTION The ECM continuously monitors its main CPU and monitor IC. This self-check ensures that the ECM is functioning properly. If outputs from main CPU and monitor IC are different and deviate from the standard, the ECM will illuminate the MIL and store this DTC.
DTC No. Detect
Front Window Fogging
DESCRIPTION If the windshield frequently fogs up even though the air conditioning system is operating, the following factors may be the cause.
Symptom Factor
Windshield frequently fogs up
Compressor with pulley assembly malfunction
Refrigerant volume (low)
Cool
