Brake Warning Alarm Inoperative

Brake Warning Alarm Inoperative





Test 1 - 7





Test 8 - 21

Circuit Description
The Brake Warning indicator illuminates and the power brake booster fluid flow alarm sounds when ground is applied to the brake warning indicator voltage 2 circuit.

Test Description
The numbers below refer to the step numbers on the diagnostic table:
4. This step tests for ground on the brake fluid level sensor signal circuit.
5. This step tests the function of the brake fluid level sensor signal circuit and the P/B Booster Fluid Flow And Pressure Alarm Delay Module.
6. This step tests for an open power brake booster fluid pressure alarm switch.
14. The P/B Booster Fluid Flow And Pressure Alarm Delay Module may be damaged if the brake warning indicator supply voltage 2 circuit is shorted to voltage.
15. This step tests the resistance value of the resistor wired in parallel with the power brake booster fluid flow alarm. The P/B Booster Fluid Flow And Pressure Alarm Delay Module may be damaged if this resistance is not within specification.
