5-62 (22) There are problems in the configuration of the airbag ECU (DTC 93D6)
When using the scan tool to test the airbag ECU, the DTC is 93D6, indicating that there are problems in the
configuration of the airbag ECU.
Step Operation Yes No
1 When using the scan tool to test the airbag ECU, is the DTC 93D6? Go to step 2 other
2Go to step 3
3 Go to step 4 Go to step 1
4 The fault has been removed, use the scan tool to eliminate the DTC.Check whether the configuration of the airbag ECU is consistent with the
actual on-board configuration?
After the troubleshooting, switch on the power supply, observe the status
of the warning light. The warning light shall goes off after lighting up for
4 seconds (self-check). (23) The impact signal output interface of the airbag ECU is short to ground or the impact output circuit is
disconnected. (DTC 93D7)
When using the scan tool to test the airbag ECU, the DTC is 93D7, indicating that the impact signal output
interface of the airbag ECU is short to ground or the impact output circuit is disconnected.IV. Diagnosis of collided vehicle No matter airbag is unfolded or folded, inspection and maintenance of collided vehicle should be performed
according to the following sequence.
1. Check ECU diagnosis signal.
(1) Connect scanner diagnosis joint
(2) Use scanner to read out diagnosis result.
2. Repair sequence
(1) when airbag is unfolded.
The following components should be replaced with new parts
a. Airbag assembly on passenger side
b. ECU
c. Airbag assembly on driver side
d. Seat belt with pretensionerNote:
due to impact, when battery power is insufficient, scanner can not communicate with ECU, now check and
service instrument board wire harness or use external power supply.SRS (Supplemental Restraint System)-SRS-General Information (2 ) Check the following components, if there is any abnormity, replace with new parts
a. Clock spring.
b. Steering wheel, steering column, lower steering shaft assembly
(3 ) The installation status of driver airbag assembly in relation to steering wheel
a. Check and see if there is abnormal noise in the steering wheel, the action of the same is good, or the
clearance is normal.
b. Check the connecter of the wire harness for damage and the terminal for distortion.

1 2 3 45-124replacing air cleaner, always ensure that no dirt enters air duct, never
use ungraded air cleaner.
(2) Simple measuring method:
(Remove joint) turn digital multimeter to ohm position, connect
two meter pens with regulator pin 1, 4 and 2, 3 respectively. Rated
resistance between 1, 4 and between 2, 3 at 20°C should be about
43.2 ohm.
9. Fuel injector
(1) ECU energizes coil of fuel injector to form magnetic field force. When magnetic field force increases to
sufficient to overcome pressure of return spring, gravity of needle valve and resultant force of frictional force,
needle valve begins to rise, oil injection process begins. When oil injection impulse cuts off, pressure of return
spring closes needle valve again.
Symptom
Poor idle speed, poor speedup, failure to start
(difficult to start)Possible cause
Since lack of maintenance, gum builds up in
fuel injector and leads to malfunction
Repair precautions:
1. there are many kinds of fuel injector, their appearance is the same, mountable fuel injector may not be the
exactly suitable one, part number of fuel injector used in repair must be consistent with original fuel injector, wrong
replacement is not permitted;
2. To facilitate installation, it is recommended to apply silicon free clean engine oil on O ring surface at upper
part connecting distributing pipe of fuel oil. Pay attention not to let engine oil contaminate fuel injector inside and
jet orifice;
3. To remove and reinstall fuel injector, O ring must be replaced, here do not damage sealing surface of fuel
injector;
4. if fuel injector has two slots, when mount buckle clamp, pay attention not to clamp in the wrong position,
refer to mounting position of original parts;
5. It is strictly prohibited to remove strainer, clean or replace strainer at discretion; 6. after removal, ensure
cleanness of fuel injector holder, avoid foreign matter ingressing the cylinder.
Simple measuring method:
(Remove joint) turn digital multimeter to ohm position, connect two meter pens with fuel injector pins
respectively, rated resistance at 20°C is 11-17 ohm.
Suggestion: use special cleaning analyzer to conduct thorough cleaning for the fuel injector per 20000km.
10. Electric fuel pump
(1) Fuel pump is a vane pump driven by DC motor, is placed in oil tank, immersed in fuel oil, utilizes fuel oil
for heat dissipation and lubrication. Storage battery supplies power to electric fuel pump via oil pump relay, the
relay switches on electric fuel pump circuit only at the time of startup and during operation of engine. When engine
shuts down due to accident, fuel pump stops running automatically.Symptom
Large running noise, poor speedup, failure to start
(difficult to start)Common cause
1. Gum builds up to form insulating layer;
2. Oil pump bushing is blocked with armature;
3. Fuel level sensor assembly is corroded etc.Engine EFI System-Engine EFI System

Lock Notes:
Wrap the sharp end of screwdriver up with adhesive tape before
operation.
4. Use screwdriver to pry open the seat belt pulley cover;
5. Unscrew the bolt and detach the seat belt ring from the car;
6. Disconnect the pre-load insertion of seat belt on the bottom edge
of the middle pillar;
7. Detach the front seat belt from the car;
8. Unfix the clip using the screwdriver and detach the trim from the
right middle pillar;
9.Unscrew two bolts using the spanner and detach the remote adjuster
assembly.
Notice:Only the ignition switch turns to "OFF" position and the battery negative should be disconncted more than
90s, the seat belt with pretensioner can be removed.
III. Seat belt with ELR and pre-tensioner
Seat belt with ELR and pre-tensioner is provided with pre-tensioner which works together with the airbag.
The pre-tensioner is part of airbag assembly. The pre-tensioner is mounted in the retractor and controlled by SDM.
When the front bumping force of the car exceeds a specific value, the pre-tensioner and airbag can be triggered
at the same time. To maintain the pre-tension type of seat belt (retractor), observe all the "Alarm" and
"Operation Instruction".
Warning:
Do not try to remove or repair seat belt pre-tensioner. If any abnormal situations take place, replace the whole
assembly with a new one.
Before working, be sure to read through "Attention for Maintenance", and observe them during working. Any
ignorance can cause injury or the failure of seat belt pre-tensioner.
IV. Inspect Operations of Seat Belt Alarm Lamp (on Driver's side)
1. Turn on the ignition switch and check if the seat belt alarm lamp flashes;
2. Fasten the belt buckle and check if the belt alarm lamp goes out;
3. Turn off the ignition switch;
4. Disconnect the seat belt buckle;
5. Turn on the ignition switch;
6. Connect wiring terminal and make earth connection, and inspect the lamp status of the seat belt. Seat belt lamp:
flashing.
V. Inspect Seat Belt
1. Confirm whether the seat belt is properly mounted.
2. Inspect whether the metal part of seat belt is damaged.
3. If the car vibrates in accidents, pull out the seat belt from the retractor and determine whether the seat belt is
scratched (load limit retractor does not work) by visual inspection and touching.
4.Inspection contents before outer seat belt instalation:When ELR
lock,check the gradient of ELR. Check and make sure the seat belt
can not be locked from any aspect within 15°.When you move the
belt ring device beyond 45° slowly,the seat belt should be locked.
5.After installation check the seat belt lock in this way that draw the
seat belt from belt ring quiekly and the seat belf can be locked
normally.
Attention:
Should the seat belt not comply with the technical specification,
you should replace it.

maintenance, and isolates the engine's noise. The engine hood has a double-lock device. The unlocking function
of the first locking is controlled by the cable handle under the instrument board. The unlocking function of the
second locking can raise the hood to a certain height. The double-lock function is designed in consideration of
safety. Especially when the vehicle is running at a high speed, it can prevent the engine hood from being raised,
which may cause traffic accident. The maximum angle at which the engine hood opens is 65°(See Fig.5-8).Fig. 5-7 Engine Hood & Front Fender
