Pinpoint Test G831824p10 : Brake Switch Circuit Test
G831824t33 : CHECK THE BRAKE SWITCH FUNCTION, WITH THE BRAKE PEDAL RELEASED
1. Set ignition status to OFF.
2. Disconnect the brake switch connector CA142.
3. Measure the resistance between:
Brake switch connector CA142, pin 02 component side
Brake switch connector CA142, pin 03 component side
-
Is the resistance greater than 5 ohms?
->YES
INSTALL a new brake switch. TEST the system for normal operation.
->NO
GO to Pinpoint Test G831824t34.
G831824t34 : CHECK THE BRAKE SWITCH FUNCTION, WITH THE BRAKE PEDAL DEPRESSED
1. Measure the resistance between:
Brake switch connector CA142, pin 02 component side
Brake switch connector CA142, pin 03 component side
-
Is the resistance greater than 10,000 ohms?
->YES
GO to Pinpoint Test G831824t35.
->NO
INSTALL a new brake switch. TEST the system for normal operation.
G831824t35 : CHECK THE BRAKE SWITCH GROUND CIRCUIT FOR OPEN CIRCUIT
1. Measure the resistance between:
Brake switch connector CA142, pin 03
GROUND
-
Is the resistance greater than 5 ohms?
->YES
REPAIR the circuit between the brake switch connector CA142, pin 03 and GROUND. For additional information, refer to the wiring
diagrams. TEST the system for normal operation.
->NO
GO to Pinpoint Test G831824t36.
G831824t36 : CHECK THE ECM TO BRAKE SWITCH CIRCUIT FOR OPEN CIRCUIT
1. Disconnect the ECM connector, FL072.
2. Measure the resistance between:
ECM connector FL072, pin 40
Brake switch connector CA142, pin 02
-
Is the resistance greater than 5 ohms?
->YES
GO to Pinpoint Test G831824t4.
->NO
No fault is indicated with the brake switch or circuit. Check the integrity of all connections and TEST the system for normal operation.
