electric room and that on the top of body are in well
connection as shown in the drawing A in next page
Check whether the wire harness of back up radar
control box is well connected with that of chassis
and that on the top of body.
Rotate the vehicle key to the ACC position and
engage the reverse gear, then measure to see whether
the back up power supply reaches to 12 V with the
multi-meter of 50 V of voltage, refer to the

and cathode lead to terminal 3, in such condition, the front wiper
motor should be in high-speed operation.
In case the operation fails to meet the requirement, change the front
wiper motor.
in operation
stop running at the stop position
a. Run the front wiper motor at low speed and stop it at any
positions excluding the stop position by disconnect the
anode lead from the terminal 2 (1).
b. Connect the terminals 2 and 5.\
c. Connect the anode lead to the terminal 6 (4) from the
accumulator, and the cathode lead to terminal 3, check
whether the wiper motor parks at the stop position after
it running for another time, if the requirement is not
satisfied, change the front brusher motor.
Remark: items in parenthesis is for Dr and SF.
Rear brusher motor inspection
Connect the anode lead to the terminal 3 from the accumulator, and
the cathode lead to terminal 4, at this time, the wiper motor will be
in normal operation, disconnect the terminal 3, the rear wiper motor
should stop running at any position excluding the stop position.

be in normal operation, under such condition, disconnect the
terminal 3, which is connected with terminal 1, and the anode lead
is connected to the terminal 2, in such case, the rear wiper motor
should stop running at the stop position.
In case the operation fails to satisfy the specified requirement,
change the rear wiper motor.
Inspection on Washer Motor
Connect the anode lead to the terminal 1 from the accumulator, and
the cathode lead to the terminal 2, at this time the washer motor
should be in normal operation.

necessary, repair or change the liquid tank.
Dismantle of Liquid Tank
1. Exhaust the refrigerant;
2. Tear down the two liquid pipes from the liquid tank;
Remark: the opened joint should be plugged with cork so as to
prevent the humid air from entering into the system.
3. Tear down the liquid tank from the tank bracket.
Mount of Liquid Tank
1. Mount the liquid tank on the liquid tank bracket;
Remark: the cover of joint should not be take down before
connecting the pipe;
2. Connect the two liquid pipes to the liquid tank;

Gearbox
Three-grade maintenance for gearbox
1. Grade I maintenance for gear box
Grade I maintenance: Check the lubricant level to see whether the lubricant level is in alignment with the lower edge of oil
filler; if the lubricant is lower than the oil filler lower edge, add the lubricant; or the insufficient lubricant will lead to the poor
lubrication or burn-out of bearing and teeth; while the over-high lubricant will cause the overheating and oil leakage.
2. Grade II maintenance for gear box
Grade II maintenance: The gear box of a new vehicle should be maintained by exchanging the lubricant during the
first grade II maintenance and should be washed with kerosene; and the lubricant quality should be checked in the
grade II maintenance in later time, if the lubricant is diluted, gumming or over-dirty, it should be changed.
3. Grade III maintenance
The gearbox should be disassembled for inspection, washing and oil change.
Notice: As the new vehicle is in the running-in status, the gearbox should be maintained by exchanging lubricant
after the vehicle covers 1500 km,
