Rewriting the programme of the engine control unit
Description of defect
In the engine, the engine speed sensor may disconnect in rare cases due to repeated thermal loading under high load conditions. If the sensor is disconnected, the engine will be controlled to prevent the engine from stalling by means of a fail-safe, but depending on the driving conditions, the engine may not be controlled in time and may stall.
Improvement details
The engine control unit program will be rewritten to prevent the engine from stalling in the event of a sensor failure. However, even in the unlikely event that the sensor is disconnected and the engine warning light illuminates, normal driving will not be affected by the new countermeasure programme.
