What to Do When the High Exhaust Temperature Indicator Light Is On?
1 Answers
When the high exhaust temperature light or DPF indicator light remains on during normal vehicle operation, it indicates that the engine is undergoing active regeneration by actively increasing the exhaust temperature to meet regeneration conditions, and does not signify an engine fault. At this time, simply ensure the vehicle is kept away from flammable areas and continue driving with increased load. If the DPF light remains on after driving with increased load for a certain distance, promptly perform a parked regeneration operation to prevent further DPF clogging. Below are relevant details: 1. When the DPF indicator light on the dashboard flashes, perform a parked regeneration operation as required as soon as possible. If driving continues, DPF clogging will worsen, and the DPF indicator light will flash while the yellow warning light illuminates, leading to engine torque and speed limitations. 2. If the parked regeneration operation is still not performed and the DPF becomes completely clogged (with the MIL indicator light and red shutdown indicator light remaining on), parked regeneration can no longer be executed. The engine will shut down after 30 seconds. This situation is not caused by quality issues, and the only solution is to contact a service station for DPF cleaning or replacement.
