REMOVAL/INSTALLATION OF AIRBAG SYSTEM 

1. REMOVAL/INSTALLATION OF AIRBAG 

Removal: 

----Disconnect the negative cable of the 

battery (—) 

Warning: When the ignition is turned off 

and at the same time the fuse is 
taken out, the airbag control 
module (BCM) can provide the 
sufficient voltage for 1 minute to 
activate the airbag. If the airbag is 
not disconnected, do not start the 
maintenance work within 1 minute 
after turning off the power supply 
to the BCM. If the airbag has been 
disconnected, the maintenance 
work can be carried out 
immediately without waiting for 
the discharging of 1 minute. The 
failure of shutting off the SRS 
system temporarily during the 
maintenance work will result in 
false ignition, physical injury and 
SRS system discarded.   

 

 

----Place the steering wheel at the center 

Warning: When dealing with the airbag, 

please face the front side of the 
module upwards so as to provide 
sufficient spreading space in case 
of false activation. The airbag may 
fly to the people or objects 
resulting in injury or vehicle 
damage due to the lack of 
spreading space.   

Remove the two airbag bolts on the steering 
wheel. 

Pull out the horn and the airbag wiring harness 
plug from the airbag. Remove the airbag.

Installation: 

----Connect wiring harness plug of the horn and airbag to the airbag socket. 

Install the airbag 

Install the airbag bolt 

Use a tightening torque of 13~17N.m to tighten the airbag bolt 

Connect it to the negative grid of the battery 

2. AIRBAG CONTROL MODULE (BCM) 

Warning: Dealing with the BCM carefully during maintenance. Do not knock or shake the 
BCM. Do not switch on the SRS circuit before installing the BCM on the vehicle. All the 
BCM bolts must be tightened carefully. In order to ensure a proper functioning of the SRS, 
the arrow on the BCM must point at the direction right ahead of the vehicle. Though the 
BCM can function when the SRS circuit is switched on before installing the BCM on the 
vehicle, it may cause a potential false activation and consequential injury. 

Notes: If there is water entering into the vehicle due to leakage, passing through deep water, 
flood or other reasons, the BCM and BCM connector may need to be replaced. Turn the 
ignition switch to the “OFF” position; check the BCM area including the carpet etc. If there is 
any obvious dipping or dipped mark, the leakage or dipped parts must be cleared, and at the 
same time replace the BCM and BCM connector. The SRS system must be disconnected 
before carrying out the operations above. Please refer to “Disconnection of the airbag 
system” of this manual.   

Removal procedure 

Disconnect the SRS. Please refer to “Disconnection of the airbag system” of this manual. 

Remove the decoration panel on the left and right sides of instrument panel. 

Loosen the safety interlock of the BCM wiring harness connector. 

Remove the BCM wiring harness connector. 

Remove the BCM fastening bolts. 

Remove the BCM. 

Installation procedure 

Install the BCM according to the arrow on the BCM, which points at the direction right ahead 
of the vehicle. 

Install the BCM fastening bolts. 

Fasten the bolts with a torque of 8--12Nm. 

Connect the BCM wiring harness connector.

Move the safety interlock head of the connector to “Lock” position. 

Install the decoration panel on the left and right of the instrument panel. 

Connect the SRS system. Please refer to the “Connection of the airbag system” of this 
manual. 

Warning: All the BCM bolts must be tightened carefully. In order to ensure a proper 
functioning of the SRS, the arrow on the BCM must point at the direction right ahead of the 
vehicle. Though the BCM can function when the SRS circuit is switched on before installing 
the BCM on the vehicle properly, it may cause a potential false activation and consequential 
injury.

3. WIRING AND CONNECTOR 

Note: The wirings assembly of the SRS 
protective supplementary system and that of 
COWL are joined together. All the wirings of 
this system are installed in a yellow corrugated 
conduit, and all the connectors is normal 
yellow. 

The wiring or the wiring connectors are to be 
replaced under the following conditions: 

(a) There are signs of damage found on the 

wiring or wiring connectors of the SRS 
protective supplementary system during 
troubleshooting. 

(b) There are signs of damage found on the 

wiring or wiring connectors of the SRS 
protective supplementary system during 
inspection. 

Note: If there is any damage found on the 
wiring of the SRS protective supplementary 
system, the whole wiring assembly should be 
replaced. 

 
 

4. SPIRAL CABLE   

The spiral cable (see the figure) is used for the 
circuit linking the vehicle body and the 
steering wheel. The steering wheel must be 
properly installed on the steering column 
when the spiral cable is located in the middle, 
otherwise the spiral cable may come loose or 
cause other malfunctions. Please refer to the 
instruction for proper installation of steering 
wheel in this manual.   

 

5. STEERING WHEEL LINER 

----The SRS airbag is installed in the steering 

wheel. The airbag includes the activator, 
igniter and air generator etc. When the 
airbag sensor assembly sends out the
