19210. INSPECT PARK BRAKE SWITCH
(1) Disconnect the connector from the park brake switch.
(2) Pull up the hand brake, inspect continuity between its terminal and ground.
Hand brake is pulled up: Continuity
Hand brake is released: No continuity
11. INSPECT BRAKE FLUID LEVEL WARING LIGHT
(1) Disconnect the connector from the brake fluid level sensor.
(2) Turn the ignition ON, the brake fluid level warning light should go out.
(3) Directly connect its connector terminal to the harness terminal with a wire, the brake fluid level warning
light should light up.
12. INSPECT BRAKE FLUID LEVEL WARING SWITCH
(1) Remove the reservoir cap
(2) Disconnect the connector from the reservoir.
(3) Inspect continuity between terminals
Float up: No continuity
(4) Use siphon to take fluid out of the reservoir.
(5) Inspect continuity between terminals
Float down: Continuity
(6) Pour the fluid into the reservoir
13. INSPECT THE REAR DEFROST INDICATOR
(1) Turn the ignition switch ON, and start the engine
(2) Press the defrost switch, the rear defrost indicator will light up
(3) Turn the ignition OFF, the rear defrost indicator should go out.
14. INSPECT THE REAR DEFOG INDICATOR
(1) The rear fog indicator will light up as the rear fog lamp lights, the terminal B1 is at the high electric
potential.
15. INSPECT THE SEAT BELT WARNING INDICATOR
(1) Disconnect the seat belt switch connector in the driver's side, the belt warning indicator should go out at
this time.
(2) Short connector terminal to the ground, the belt warning indicator should light up.

291IV. ABS Operation Inspection1. Check the Wheel Speed Sensor Output Voltage
1Check whether the clearance between the wheel speed sensor and the ring gear is within the specification
For front wheel standard value, refer to "Front Wheel Sensor Installation Drawing"
For rear wheel standard value, refer to "Rear Wheel Sensor Installation Drawing"
3Jack up the wheel and release the manual brake
2Remove the ABS wire harness, measure at the wire harness connector
4Rotate the wheel at the speed of 1/2 turn/second, and use the multimeter or oscilloscope to measure the
output voltage
Terminal 1-2
Terminal 19-20
Terminal 5-6
Terminal 22-23
Output Voltage
zWhen use the multimeter to measure
For front wheel, refer to "Front Wheel Sensor Drawing".
For rear wheel, refer to "Rear Wheel Sensor Drawing".
zWhen use the oscilloscope to measure
For front wheel, refer to the related standard.
For rear wheel, refer to the related standard.
5The fact that the output voltage is not within the above range may result from the following causes:
zExcessive clearance between the sensor and the ring gear.
zSensor fault.
zCheck the sensor resistance£¨1.0 - 1.3k¦¸£©.
zSelect the 4 points on the ring gear to check the clearance (ring gear distortion) between the ring
gear and the wheel speed sensor.
2.Check the Hydraulic Control Unit (HCU).
1Jack up the vehicle, make sure the wheel can rotate freely.
2Release the manual brake.
3Turn the ignition switch to ON after connecting the scan meter, do not start the engine this time.
4Refer to the HCU Diagnosis for inspection.
Note: when connecting or removing the scan meter, the ignition switch must be turned to OFF.
