Safety information
In order to facilitate customers to perform fault diagnostics and maintenance, according to the requirements of relevant regulations such as OBD2 Euro IV & National IV, the
instrument is equipped with the engine failure signal light.
The instrument engine failure light has 2 operating modes, with the following specific functions:
1. Normal mode: (Regulatory requirements) When the axis lock key is turned on, the vehicle does not start and the failure lamp is on. After the engine starts, the failure lamp will
disappear if there is no failure & will remain on if there is failure.
2. Failure lamp flickering mode: When the axis key is turned on, quickly turn on & off the key for 3 times repeatedly to trigger the flickering mode. Regardless of whether the engine
is started, the lamp will be off when there is no failure and it will flicker regularly when there is a failure. Wait for 5 seconds or more after turning off the axis lock key, the ECU
automatically exits the “Failure lamp flickering mode” and shifts to “Normal mode”.

E.g.: If the failure lamp first flickers 5 times and subsequently 7 times, it reflects & indicate failure Code 57 (Open circuit of oxygen sensor heating), and
require
checking on the oxygen sensor.
