VALUES ON THE DIAGNOSIS TOOL
CAUTION:
The display shows the control unit calculation data, so a normal value might be displayed even in the event the output circuit (harness) is open or short-circuited.
Note 1:
Confirm tire pressure is normal. Note 2
: On and off timing for warning lamps and indicator lamps.
Refer to BRC-22, "VDC/TCS/ABS : VDC Function".
Refer to BRC-24, "VDC/TCS/ABS : TCS Function".
Refer to BRC-26, "VDC/TCS/ABS : ABS Function".
Refer to BRC-27, "VDC/TCS/ABS : EBD Function".

The heated oxygen sensor 2 has a much longer switching time
between rich and lean than the air fuel ratio (A/F) sensor 1. The oxygen
storage capacity of the three way catalyst 1 causes the longer
switching time. To judge the malfunctions of heated oxygen sensor
