B: INSPECTION
Check that connector is connected correctly and that con-
nector terminal sliding resistance is correct.
G4M0469
C: INSTALLATION
1) Connect connector to ABS control module.
2) Install ABS control module on the body.

17. G Sensor for ABS System (Except
ABS 5.3 Type)
A: REMOVAL AND INSTALLATION
The G sensor is located on the right front wheel apron.
G4M0471
B: INSPECTION
1) Check to ensure that G sensor is securely installed on
front wheel apron, and that connector is properly installed.
2) Disconnect connector from G sensor and measure con-
tact resistance between terminals.
Condition of G sensor Standard
On flat surface 610±60Ω
* When slanting about
14°—21.3°(θ)610±60Ω,
More than 100 kΩ
NOTE:

Tilt G sensor forward as shown in Figure. If it is tilted
backward, it will not operate.

Hysteresis occurs during ON-OFF operation of sensor.
Sensor should turn OFF from ON (610Ω,More than 100
kΩ) when it is tilted in a range from 14°to 21.3°.
Tightening torque:
7.4±2.0 N⋅m (0.75±0.2 kg-m, 5.4±1.4 ft-lb)

18. Brake Hose and Pipe
SUPPLEMENTAL RESTRAINT SYSTEM“AIRBAG”
Airbag system wiring harness is routed near the center
brake pipe.
CAUTION:

All Airbag system wiring harness and connectors
are colored yellow. Do not use electrical test equip-
ment on these circuit.

Be careful not to damage Airbag system wiring har-
ness when servicing the center brake pipe.
A: REMOVAL AND INSTALLATION
CAUTION:

When removing and installing the brake pipe, make
sure that it is not bent.

After installing the brake pipe and hose, bleed the
air.

After installing the brake hose, make sure that it
does not touch the tire or suspension assembly, etc.
