Daily maintenance of electronic control
differential lock system *
Electronically controlled differential lock system
consists of mechatronics components. It is highly
reliable and usually does not require regular
maintenance. Paying attention to the following
aspects will help improve system performance and
reduce system fault rate:
● The ECU of electronic control differential lock is
composed of precise electronic parts. Strong
collision and knocking are easy to damage the
electronic parts. Therefore, the ECU shall be
avoided to be collided.
● Do not contaminate the electrical connectors of
the electronic control differential lock system,
especially the metal terminals, so as to avoid poor
electrical contact;
● After the vehicle is driven off-road on non-paved
roads, it is necessary to inspect the electrical
connectors and line speed of the electronic control
differential lock on the front and rear axles in time
to avoid contamination with sediment or other
debris.
Crawl control (CCO)
Introduction to system
The crawl control focuses on low-speed off-road
driving. When the vehicle is in 4L mode and the
transmission is in D/M, it allows the driver to set and
maintain a steady speed, reducing the difficulty of
driver operations and allowing the driver to
concentrate more on turning and finding a path
through the obstacle.
● The crawl control is only an auxiliary
system, which cannot substitute the
judgment of the driver on the surroundings
and road conditions, not even driving the
vehicle for the driver. In any case, the driver
must concentrate on driving carefully and be
responsible for the vehicle safety.
● Incorrect use of the crawl control may cause
collisions and damages to the vehicle.
● If the crawl control displays any indicator
light or fault message on the instrument, do
not use this function to go down a steep slope.
● Prolonged use of the crawl control may cause
overheating of the relevant system. When the
instrument prompts "The brake system is
too hot, please use the crawl control with
caution", please stop using the function and
wait until it cools down.
