    Customer Concern: The brake lights are inoperative.
    Tests/Procedures: 1. Check the stop light fuse for battery voltage at all times.

    2. At lamp failure module, check to see if there is battery voltage on the Green/White wire with the brake pedal pushed.

    3. Check to see if there is battery voltage to the Green/Red wire with the brake pedal pushed.

    4. Bypass the lamp failure module by jumping the Green/White to the Green/Red. Check the light operation. All lights should be illuminated similarly. All bulbs should be of the same make and model.

    5. Check the grounds for the brake light bulbs and the lamp failure module.
    Potential Causes: Harness
    Lamp Failure Module

    Tech Tips: The lamp failure module is a common failure item. There is usually a problem with the bulbs being incorrect or there is a poor ground that causes the module to fail.
