Question

When is a tractor ABS self-test performed?

a) every time the brakes are released
b) each time the ECU is activated
c) each time the ignition key is switched off
d) when a fault code is logged

Answer 1

The ABS self-test in a tractor is performed each time the ECU is activated. Hence the correct answer is option B

Step-by-step explanation:

The correct answer is option b) each time the ECU is activated.

ABS stands for Anti-lock Braking System, and it is a safety feature in tractors that prevents the wheels from locking up during braking, allowing the driver to maintain steering control. The ABS self-test is performed each time the Electronic Control Unit (ECU) of the tractor is activated, which typically happens when the ignition key is switched on. During the self-test, the ECU checks the ABS system for any faults or malfunctions.

Hence the correct answer is option B
