Steering System Maintenance
Structure Introduction
The steering wheel has an airbag module which should only be inspected and repaired by a professional. The
steering column's upper section adopts a steel deformation and energy absorbing crumple structure which
ensures collision protection for the driver. The lower section uses a high precision sliding spline structure,
which can effectively eliminate structural interference caused by body deformation. The steering column angle
is adjustable, which can more easily adapt to the driver, and at the same time possesses reasonable reverse
efficiency to ensure the driver has a good feel for the road. Steering sys\
tem is as shown below:
Steering column assembly removal and
installation
1. Remove the airbag.
(a) Disconnect the battery's negative cable, and wait for
one minute before canceling the airbags function in
order to avoid unnecessary injury.
(b) To ensure steering column's proper installation, during
the entire removal process, the front tires must keep
straight.
(c) Remove the two hexagon screws and the airbag module.

Immobilizer System
Immobilizer system composition
This vehicle's engine immobilizer system consists of a theft deterrent ECU assembly, a theft deterrent coil as-
sembly, and two theft deterrent converter assemblies. The theft deterrent coil assembly is put on the head of
ignition lock cylinder, with the other end connected to the theft deterrent ECU assembly. The two theft deterrent
converter assemblies are separately installed inside the plastic handles\
of the two keys.
1. Position diagram
All the components of immobilizer system are assembled on the overall vehicle except for the theft deterrent
converter assemblies inside the keys. They achieve communication functions via the wire harness connections.
The following figure shows the position of each component in the overall\
vehicle.
Theft deterrent controller
Ignition lock key
Theft deterrent coil
Steering column
2. Theft deterrent controller
The theft deterrent controller assembly mainly consists of a microprocessor and peripheral components. It com-
municates with the password transmitter assembly and engine ECU. The theft deterrent controller assembly
communicates with the engine ECU via the W wire, while communicating with the theft deterrent transponder
assembly via radio frequency. The theft deterrent controller connects with the scanner via the K wire. Through
the scanner, it can initiate matching, state controlling, and malfunction diagnosti\
c on the immobilizer system.
3. Theft deterrent coil
The theft deterrent coil assembly is installed on the ignition lock cylinder, the other end of wire harness
plug is connected to the theft deterrent controller assembly. The theft deterrent coil assembly can generate
an electromagnetic field to achieve communication between the theft deterrent controller assembly and the
password transmitter assembly.
4. Transponder
The theft deterrent transponder is installed inside the key handle. It has no power supply, maintains a small size,
and long use life. It acquires electric energy and transmission signals using the stimulation of the electromagnetic
field generated by the theft deterrent coil, so as to communicate with t\
he theft deterrent controller assembly.

not necessarily mean that engine start failure is due to a immobilizer system malfunction. The reasons for start-
ing engine failures are numerous, including factors like fuel, gas, fire, electricity, wires, etc. If the engine cannot
start, first check if the immobilizer system is working normally. This can be judged by looking at the flashing
theft deterrent indicator lamp which is located on the dashboard in front of the driver seat: Insert the key into the
lock cylinder and turn it to the "ON" position. If a legal key is used to start the engine, once the warning lamp is
connected to the ON end and the transponder is confirmed, the LED will remain unlit. Then when the ON end is
disconnected and the key is pulled out, the LED will shine for 0.25 s and darken for 4 s, as to act as a warning.
If an illegal key is used to start up the engine or there is something wrong with the system, the alarm indicator
lamp will shine for 0.25 s and darken for 4 s. If all is normal, then check the other parts of the engine. If abnor-
mal, first perform immobilizer system troubleshooting. A scanner can be used to judge if the immobilizer system
is working normally, but the precondition is that the scanner must be able to establish communication with the
theft deterrent controller.
1. If communication cannot be established, consider the following:
(a) Check whether the battery voltage is higher than 9 V
(b) Check whether the scanner plug is well contacted to the vehicle socket
(c) Use a multimeter to check whether the 7 pin of the OBD-II plug (diagnostic plug) is connected to the theft
deterrent controller's A7 pin
(d) Check whether the power supply of the theft deterrent controller is normal. (Use a multimeter to measure
whether the voltage of the theft deterrent controller's socket A1 pin and A2 pin is higher than 9 V)
(e) Then adopt the substitution method, which is to replace the theft deterrent controller to check if there is
anything wrong with the theft deterrent controller.
• If the failure is related to the theft deterrent controller, change it and initiate re-matching.
• If the failure has nothing to do with the theft deterrent controller, remove the electronic controller which
is connected to the alarm's K wire, such as the ABS controller, engine electrojet controller, airbag ECU
assembly, etc., as to ascertain if the present fault is caused by the wire harness connected with the theft
deterrent controller's K wire.
2. If communication can be established
Connect the scanner to the vehicle diagnostic port. Insert the key into the steering lock, and turn it to the "ON"
position, then select the scanner to check the immobilizer system's trou\
ble code.
3. Security system troubleshooting
Investigate the problem and perform troubleshooting according to the tro\
uble code on the scanner:

multimeter to check the resistance between the B1 and B2
pins. The normal resistance is about 5-30 Ω. If the resistance
is close to zero, that means the coil has been short circuited.
If the resistance is infinite, then it means the coil's circuit is
open. Measure the resistance between pins B1 and B3, and
B2 and B3, normally they are infinite. If the resistance gains
a certain value, then it means the coil is short circuited or
leaking electricity.
If there is nothing wrong with the coil, the next step is to 4.
check the theft deterrent controller. Adopt the substitution
approach, replace it with a non-matched new theft deterrent
controller or an theft deterrent controller which has been
reset (please refer to the immobilizer system component
replacement). Insert the key into the ignition lock and turn it
to the "ON" position and read the trouble code. If there is no
9000 failure, it means the replaced controller has an internal
malfunction, and the new replaced controller must be re-
matched.
