17. G Sensor for ABS System
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°.

3. CHECK A.B.S. SENSOR MECHANICAL TROUBLE.
1) Dismount brake as outlined in manual to gain access to
A.B.S. sensor and tone wheel for inspection.
2) Check pole piece and tone wheel for accumulation of
foreign particles. If necessary, remove foreign particles and
clean.
3) Check tone wheel teeth for cracks for deformities. If
necessary, replace tone wheel (No. of teeth: 44) with a new
one.
4) Check tone wheel for looseness.
Tightening torque:
10 — 16 N⋅m (1.0 — 1.6 kg-m, 7 — 12 ft-lb)
5) Measure tone wheel-to-pole piece gap over entire
perimeter of the wheel.

If measurements check out“Not OK”, adjust the gap using
spacers (Part No. 26755AA000). If spacers cannot correct
the gap, replace worn sensor or worn tone wheel.
