2009 CHERY TIGGO airbag off

Downloaded from www.Manualslib.com manuals search engine NOTE :
The Restraints Control Module (RCM) ground pin must be connected to the vehicle chassis in the immediate location
of the RCM mounting area.
WARNING!
After installing the Restraints Control Module (RCM), make sure all of the connectors are firmly connected, and
the harness is routed properly. The resistance between the RCM housing and the vehicle body should be less
than 100 m.

- Open Ignition switch: ON This DTC will set if
the airbag warning
lamp driver circuit is
shorted to ground or
open between the
airbag warning lamp
and the Restraints
Control Module
(RCM). •

cluster and RCM
• RCM
DTC Confirmation Procedure:
Before performing the following procedure, confirm that battery voltage is more than 12 V.
• Turn ignition switch off.
• Connect the X-431 scan tool to the Data Link Connector (DLC) - use the latest software available.
• Turn ignition switch on.
• With the scan tool, record and erase stored DTCs in the RCM.
• Turn ignition switch off and wait for a few seconds.
• Turn ignition switch on then select view DTC.
• If the DTC is detected, the DTC condition is current. Go to Diagnostic Procedure - Step 1.
• If the DTC is not detected, the DTC condition is intermittent (See Diagnostic Help and Intermittent DTC Trou-
bleshooting in Section 14 Restraints for more information).
Diagnostic Guide Lines
Observe the following guide lines while diagnosing this DTC:
•Troubleshoot any Engine Control Module (ECM) charging/cranking DTCs before proceeding.
• If the warning lamp goes out immediately after the warning lamp flashed for6-7seconds, this indicates that
the system is OK.
• If the warning lamp is on for6-7seconds continuously, then goes out, or the warning lamp is on continuously,
this indicates that there are history DTCs in the system. Use the Scan Tool to erase the DTCs.
• If any other condition occurs, use the Scan Tool to erase the history DTCs first, then check the warning lamp.
If the warning lamp does not go out immediately after the warning lamp flashes for6-7seconds when using
the Scan Tool, erase the history DTCs first.
• In the course of troubleshooting the airbag system, make sure the system power supply is shut off, and wait
two minutes for the system capacitor to discharge.
• The squib circuit connectors integrate a shortingspring (which prevents the airbag from deploying unintention-
ally due to static electricity by shorting the positive wire to the negative wire in the squib circuit when the con-
nectors are disconnected). Therefore, if the airbag electrical connector or spiral cable electrical connector is
damaged or improperly connected, the shorting spring may not be released when the electrical connector is
connected.
• The following tools are required to perform the DTC diagnostic procedure:
X-431 Scan Tool
Airbag Special Load Tool
Digital Multimeter

Airbag System Disarming Procedure
Description
WARNING!
The steering column contains the driver’s airbag. The airbag system is a sensitive, complex electro-mechanical
unit. Before attempting to diagnose, remove or install the airbag system components, you must first disconnect
and isolate the negative battery (ground) cable. Then wait two minutes for the system capacitor to discharge.
Failure to do so could result in accidental deployment of the airbag and possible personal injury. The fasteners,
screws, and bolts, originally used for the airbag components, have special coatings and are specifically
designed for the airbag system. They must never be replaced with any substitutes. Anytime a new fastener is
needed, replace with the correct fasteners provided in the service package or fasteners listed in the parts books.
1. Turn the ignition off.
2. Disconnect and isolate the negative battery cable.
3. Wait two minutes for the system capacitor to discharge.
4. The airbag system can now be serviced safely.
Driver Side Airbag
Removal & Installation
1. Turn the ignition off.
2. Disconnect the negative battery cable.
WARNING!
Wait two minutes for the airbag system reserve capacitor to discharge before beginning any airbag system or
component service. Failure to do so may result in accidental airbag development, serious or fatal injury (See
Airbag System Disarming Procedure in Section 14 Restraints).
3. Remove the two driver side airbag retaining bolts (1).(Tighten: Driver side airbag retaining bolts to 10
N·m)
4. Remove the driver side airbag and disconnect the airbag squib electrical connector.
5. Installation is in the reverse order of removal.
