What's wrong?
The fire suppression relay cable on 2021-2024 Gillig Low Floor buses supplies power to the relay for the fire suppression system. A relay is an electrical switch; when the system needs power routed, the relay opens or closes that circuit. The cable and relay have to stay insulated and secure so the circuit stays protected.
On affected buses, the relay power cable is too short. That short length pulls the positive terminal into a tight bend, which puts the cable insulation against the relay mounting bolt. Normal movement and vibration then let the bolt rub through the insulation sleeve. Once the insulation is damaged, the relay cable can fail and the fire suppression relay can stop working as designed.
Gillig is not aware of an early warning for this problem. There is no warning sign before failure, so a bus operator should not rely on a light, sound, or visible symptom to identify the defect.
Who's affected?
The same relay cable appears under wiring and emergency fire-suppression equipment, so either component label points to the same recall scope.

What happens at the repair
At the dealer, a Gillig technician replaces the fire suppression relay cable covered by the recall. The cable is the part that can be damaged by chafing against the mounting bolt, so the repair removes that failure point. Parts and labor are covered at no charge. Out-of-pocket relay cable repairs already paid are handled through Gillig's existing warranty, not through a separate reimbursement program. Ask the service desk how warranty coverage applies if you have prior repair paperwork.
