CHERY SQR7080 EZ Drive SERVICE MANUAL

MECHANICAL TRANSMISSION – WIRE HARNESS

The wire harness is integrated with the hydraulic unit and bundles eleven connectors for different

components.

Five main electromagnetic valves are placed together on one sleeve and the plate is fixed onto the hydraulic

block.

The electric pump is mounted onto the clutch cylinder body.

Connection with the vehicle wire harness is implemented through the 24-line SICMA connector on the

system.

Line distribution of the connector:

A8 - à control + electric pump set

B2 à control + clutch electromagnetic valve

B3 à control + gear engagement electromagnetic valve 2

B4 à control + gear position selection electromagnetic valve 3

B5 à control + gear engagement electromagnetic valve 1

B6 à control + gear position selection electromagnetic valve 4

Sensor:
– For power on

C1 --- – For clutch

– For pressure

C2 ß gear engagement sensor signal

C3 ß gear position selection sensor signal

C4 ß clutch sensor signal

C5 ß pressure sensor signal

C6 --- blocky – transmission input speed sensor

C7 ß signal + transmission input speed sensor

Control + sensor:

- For power on

C8 - à gear position selection

– For clutch
– For pressure

ß - Input

- à Output

MECHANICAL TRANSMISSION – GEARSHIFT LEVER

Method of application:

For control lever type gearshift, there is only one

stable position.

Any operation of the gearshift lever from this

position will produce a pulse, which is also called
“signal”.

– Forwards (+): to high drive ratio
– Backwards (-): to low drive ratio
– Rightwards (N): to the neutral position
– Rightwards and backwards

: to the

reverse gear

The button “A” is used to activate or inactivate the

automatic mode depending on what the driver

needs.

The display in the center of the instrument board

indicates the actual drive ratio in use. The letter

on the base frame of the gearshift lever is used to

indicate that changing to this position will change to

the reverse gear.

Operation:

Its

control

of

the

automated

mechanical

transmission is an electric control.

Gearshift lever position is converted into electric

signal through the connector located at the bottom

of the control module and then sent to the

transmission computer.

Removal:

Disconnect the battery.

Remove:

– Gearshift lever base frame dust boot

– Transmission base

Disconnect electric connection of the gearshift lever.

Take out the following two electric wires of the

gearshift lever's electric connector:

Line 8 – power wire for the automatic operation

button

Line 9 – power wire for the serial operation button

On the main shaft of the connector, line distribution

(10 lines) is as follows:

Line 1: control lever mechanism

Line 2: information of changing to high drive ratio

Line 3: information of changing to low drive ratio

Line 4: stable position information (spare)

Line 5: information of changing to the neutral

position

Line 6: whole module

Line 7: information of changing to the reverse gear

Line 8: whole module

Line 9: information of changing to the automatic

mode

Line 10: no connection

Undo the circlip that surrounds the gearshift lever

base washer.

Remove the ball ring on the top of the gearshift

lever by applying an upward force on it, as shown in

the arrow.

Remove the four fixing bolts for gearshift lever base

from its mounting base.

Replace any worn parts.

Reassembly:

It is easy to carry out the reassembly procedure,

which is opposite to the disassembly procedure.

MECHANICAL TRANSMISSION – SPECIAL REQUIREMENTS ON REPLACEMENT OF

SYSTEM AND COMPONENTS

KIT hydraulic unit/computer/transmission/reprogramming

(A) Ignition

Re-initialization after all experiments (attempts) are carried out: RZ002 “attempt”

(B) Title: control of VP008 “Gear position selection & gear engagement attempt”

Wait until the program comes to an end

Turn off the engine

Wait for one minute

Ignite the engine (if any fault occurs, the buzzer will be started)

If the check result is OK, ET061 "Region Qualified" will be shown. If the “Region finished” or

ET063 “Electromagnetic valve is null” is shown, repeat the procedure (B).

(C) Apply all drive ratios (the information shown on the display on the instrument board should be OK)

(D) Place the gearshift lever to the neutral position

Start the engine

Wait for ten seconds (used in important clutch experiments) and provide no speed.

If the check result is OK, ET062 “Important experiments finished” will be shown. Otherwise,

repeat the procedure (D).

(E) When the "clutch temperature" information PR095 is less than 1800C, repeat the engine start-up

process with halfload five to six times (used in step-by-step attempt for clutch)

Turn off the engine

Wait for one minute

Ignite the engine

If the check result is OK, ET065 “Step-by-step attempt finished” will be shown. Check whether

the “Step-by-step” information is changing, and if not so, repeat the procedure (E).

(F)

Title: control of CF321 “Transmission model” selection: short-size or long-size

Check that the “Transmission model” information shown is really that model that the operator

selected.

(G) Turn off the engine

Engagement position sensor/gear position selection sensor

(A) Ignition

Ensure no fault

(B) Title: Control of VP008 "Gear position selection & gear engagement attempt"

Wait until the program comes to an end

Wait for one minute

Ignition (if any fault occurs, the buzzer will be started)

If the check result is OK, ET061 “Region Qualified” will be shown. If the “Region finished” or

ET063 “Electromagnetic valve is null” is shown, repeat the procedure (B).

Apply all drive ratios (the information shown on the display on the instrument board should be OK)

(C) Turn off the engine

Clutch position sensor/clutch

(A) Ignition

Ensure no fault
