INSPECTION PROCEDURE
NOTICE:
HINT: Operating the ignition switch, any switches, or any doors triggers related ECU and sensor communication with the CAN. This communication will cause the resistance value to change.

Precaution
1. INSPECTION PROCEDURE FOR VEHICLE INVOLVED
IN ACCIDENT
Perform the zero point calibration and sensitivity
check if any of the following conditions occur.
The occupant classification ECU is replaced.
Accessories (seatback tray and seat cover, etc.)
are installed.

Inspection
1. INSPECT REAR SPEED SENSOR
(a) Disconnect the skid control sensor connector.
(b) Measure the resistance between terminals 1 and 2
of the skid control sensor connector.
OK:
Resistance:
less than 2.2 kΩ
(c) Measure resistance between each of terminals 1
and 2 of the skid control s ...
