Combination Meter
If something is wrong with the meter, check the relevant component and circuit according to the connector defi-
nition. If the failure still cannot be eliminated, check whether the instrument itself has malfunctioned in the fur-
ther steps. The following diagram shows the view of the meter connector and its numb\
er.

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.

Rotary vane compressor’s operation
As the diagram shows, when the rotor is rotating under an
external force, due to the synergism of centrifugal force and the
oil pressure difference on the five vanes of the rotor, their edge
clings to the cylinder wall. Because the fixed cylinder is oval
shaped, while rotating on the rotor, the rotor vanes spread and
retract according to the cylinder's geometrical shape, which in
turn makes the crescent shape consisting of the cylinder, vanes,
etc. to change continuously, so as to achieve the functions of
suction, compression, and exhaustion.

Areas of Importance
1. While performing maintenance on the SRS airbag, make sure to work in accordance with this
chapter's steps and notes.
2. Be sure to use the specified test apparatus and SST (Special Service Tools) which are mentioned in this
chapter.
3. While performing maintenance on the following mentioned components, if there is any problem with a
component, be sure to replace it with a new one.
• Airbag ECU assembly.
• Clock spring assembly.
• Driver side airbag assembly.
• Front passenger side airbag module.
• Driver side preload seat belt.
• Front passenger side preload seat belt.
• Airbag wire harness.
4. While performing maintenance, please disconnect the battery's negative terminal connector, and then
after waiting for 60 s, commence operation. Furthermore, wrap up the removed negative terminal with
insulating tape.
After the battery power is cut off, the capacitor in the airbag ECU will still maintain a set amount of electrical
energy. If used without waiting a sufficient amount of time, it may lead to serious injury and accidents due to
the airbag's faulty deployment.
5. When painting the vehicle, excessive heat may influence the components, in which case the SRS-ECU,
airbag module, clock spring, etc., should first be removed and set aside\
.
Use a diagnostic scanner to clear the trouble code after the SRS airbag is repaired, as to ensure the warning
lamp will continue to work normaly.
