BENDIX GSBC SYSTEM TROUBLESHOOTING CONT.
TEST 2: REVERSE VALIDATION TEST CONT.
Test Procedure (cont.)
10. When the dashboard displays “Test Active Release Brake Pedal,” fully release
the service brakes and keep them released.
At this point, there will be no brakes applied on the vehicle. It is the operator’s
responsibility to ensure that the vehicle is parked on level ground and the
wheels are chocked before the test begins to prevent unintended vehicle
movement. If the vehicle begins to move, apply the service and/or parking
brakes. Once the vehicle is safely stopped, chock the wheels, and restart the
test. Failure to chock the wheels could result in a potential collision, property
damage, serious injuries, or death.
11. After all components have been tested, the test will complete automatically
with three possible outcomes:
A. The test passed.
• If the test completed successfully, “Test Completed Vehicle Ready To
Use” will be displayed. The fault has been cleared, and any warning
lamps on the dashboard related to that fault will be turned o.
B. The test fails due to preconditions not being met.
• If the brake pedal is not pressed correctly, the “Test Failed Brake
Pedal Operation Incorrect” message may appear.
NOTE: This does not necessarily indicate a fault with the foot brake
module, only that the test was not operated correctly.
• If the vehicle begins to move during the test, “Test Aborted Vehicle
Moving” will be displayed on the dashboard.
In order to reset the vehicle to repeat the test, make sure the
preconditions are met and then complete the following steps:
1. Make sure the vehicle is parked.
2. Turn the vehicle ignition o.
3. Exit the vehicle, close all doors, and lock the vehicle.
4. Chock the wheels to prevent vehicle motion.
5. Remain outside the vehicle for at least 90 seconds to allow the
brake controller to reset.
NOTE: Do not press the brake pedal during this time or the
brake controller will not reset.
