3.
(B20) BRAKE FLUID LEVEL SWITCH SENSE CIRCUIT SHORT TO GROUND
Turn the ignition off.
Disconnect the Brake Fluid Level Sensor harness connector.
Disconnect the Anti-lock Brake Module harness connector.
NOTE: Check connector - Clean/repair as necessary.
Measure the resistance between ground and the (B20) Brake Fluid
Level Switch Sense circuit.
Is the resistance below 5.0 ohms?
Yes
>> Repair the (B20) Brake Fluid Level Switch Sense circuit
for a short to ground.
Perform ABS VERIFICATION TEST - VER 1. (Refer to 5 -
BRAKES/ELECTRICAL - DIAGNOSIS AND TESTING)
No
>> Go To 4
4.
BRAKE FLUID LEVEL SENSOR
NOTE: Determine if the Brake Fluid Level Sensor is stuck in the down position. Repair as necessary.
Measure the resistance of the Brake Fluid Level Sensor at the sensor terminals.
NOTE: Resistance should be approximately 10,000 ohms with the reservoir full.
Is the resistance between 9,500 and 10,500 ohms?
Yes
>> Go To 5
No
>> Replace the Brake Fluid Level Switch in accordance with the Service Information.
Perform ABS VERIFICATION TEST - VER 1. (Refer to 5 - BRAKES/ELECTRICAL - DIAGNOSIS AND
TESTING)
5.
(Z420) GROUND CIRCUIT OPEN OR HIGH RESISTANCE
Using a 12–volt test light connected to 12 volts, check the (Z420)
Ground circuit.
NOTE: The test light should be illuminated and bright. Compare
the brightness to that of a direct connection to the battery.
Is the test light illuminated and bright?
Yes
>> Replace the Anti-lock Brake Module in accordance with
the Service Information. Refer to the symptom *Replacing
the Anti-lock Brake Module for additional information.
Perform ABS VERIFICATION TEST - VER 1. (Refer to 5 -
BRAKES/ELECTRICAL - DIAGNOSIS AND TESTING)
No
>> Repair the (B20) Brake Fluid Level Switch ground circuit
for an open circuit or high resistance.
