6) Disconnect side-sensor connector sliding connector
outer (1) as shown.
Installation
CAUTION!
Proper operation of side-sensor requires
sensor be rigidly attached to specified
position.

1) Check that none of following faulty conditions exists.
• Bend, deformity or rust of under body.
• Foreign matter on mating surface of sensor.
2) Install side-sensor (1) on under body (2) and tighten side-sensor bolt (3) to specified torque.
Tightening torque
Side-sensor bolt (a): 9 N·m (0.9 kgf-m, 6.5 lb-ft) 3) Connect side-sensor connector pushing connector
inner (1) as shown.
4) Connect negative cable at battery.
5) Enable air bag system. Refer to “Enabling Air Bag System”.
Side-Sensor InspectionS7RS0B8206016
WARNING!
During service procedures, be very careful
when handling a sensor.
• Never strike or jar a sensor.
• A sensor and mounting bracket bolts must be carefully torqued to assure proper
operation. Under loose connection, it
could cause improper operation of the air
bag system.

CAUTION!
• Never disassemble side-sensor.
• Sensor should be replaced when it was dropped from a height of 90 cm (3 ft) or
more.

The circuit diagram is designed so the current flows from the top of the diagram (power source) to the bottom of the
diagram (ground) as if giving an image of water flow.
[A]: Fuse No.
[B]: Circuit jumping page / direction
NOTE
This means “Jump to the page directed with the arrow(s) by their number.
(For example:” Two arrows directing left” means” Jump to two pages before”.)
You will find the same symbol with the arrows directing opposite in the referenced page. The circuit
continues between the symbols.

[C]: Circuit jumping point / direction
NOTE
The circuit continues to the same symbol with opposite direction within the page.
You will find the other symbol in the direction of the arrow.
