The fault light of the new Shengda EPB is on. Why?

Question? What is the reason why the fault light of Xinshengda EPB is on?

Main answer

When the car first breaks down, it is when the engine is started that the shift lever cannot move out of P gear, and at the same time, the engine fault light and EPB system fault light will light up. Later, the customer used the emergency way of manual unlocking to move the gear lever out of the P position. At this time, the vehicle can run, but there will be obvious impact when shifting gears. However, these failures will not last. Sometimes, as long as the customer moves the gear lever several times after stopping the vehicle, the fault phenomenon may disappear. After learning these faults, our maintenance technicians first scanned the MI codes of all systems of the automobile with the original GDS diagnostic instrument. The results show that the engine system did not record the fault code, while the automatic transmission system and EPB system recorded the fault codes P0705 and C 1646 respectively.
