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:

Check whether the theft deterrent coil's connecting plug and 1.

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.
