(g) Ignition switch turn to OFF.

(h). Measure the resistance between terminals No.3 / No.6 of connector IP01 and the body ground respectively

with a multimeter.

Standard Resistance: Less than 1 Ω

Confirm whether the measured value is accorded with the standard.

3

Check brake fluid fluid sensor .

A. Disconnect the harness connector of the brake fluid level sensor.

B. Measure the resistance between 2 terminals of the brake fluid level sensor with the universal meter.

Standard resistant value: infinity

C． Confirm if the resistance conforms to standard value.

4

Check brake fluid level sensor harness.

(a) Disconnect combination instrument harness

connector IP02.

(b) Use multimeter to measure resistance between

IP02 terminal 9 and CA20 terminal 1.

(c) Use multimeter to measure resistance between
