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:
