CHERY TIGGO 2009 Service Repair Manual

Downloaded from www.Manualslib.com manuals search engine GENERAL INFORMATION
Description
Available occupant restraints for this vehicle include both active and passive types. Active restraints are those which
require the vehicle occupants to take some action to employ, such as fastening a seat belt; while passive restraints
require no action by the vehicle occupants to be employed.
Active Restraints
•Front Seat Belts
• Rear Seat Belts
Passive Restraints
• Driver Airbag
• Passenger Airbag
• Seat Belt Tensioners
Operation
Active Restraints
The primary passenger restraints are the seat belts. Seat belts are referred to as an active restraint because the
vehicle occupants are required to physically fasten and properly adjust these restraints in order to benefit from them.
Passive Restraints
The passive restraints are referred to as a supplemental restraint system because they were designed and are
intended to enhance the protection for the occupants of the vehicle only when used in conjunction with the seat belts.
They are referred to as passive restraints because the vehicle occupants are not required to do anything to make
them operate; however, the vehicle occupants must be wearing their seat belts in order to obtain the maximum safety
benefit from the supplemental restraint system.
The supplemental restraint system electrical circuits are continuously monitored and controlled by a microprocessor
and software contained within the Restraints Control Module (RCM). An airbag indicator in the instrument cluster
illuminates for about seven seconds as a bulb test each time the ignition switch is turned to the ON or START posi-
tions. Following the bulb test, the airbag indicator is turned ON or OFF by the RCM to indicate the status of the
supplemental restraint system. If the airbag indicator comes ON at any time other than during the bulb test, it indi-
cates that there is a problem in the supplemental restraint system electrical circuits. Such a problem may cause
airbags not to deploy when required, or to deploy when not required.
Deployment of the supplemental restraints depends upon the angle and severity of an impact. When an impact is
severe enough, the microprocessor in the RCM signals the inflator of the appropriate airbag units to deploy their
airbag cushions. The front seat belt tensioners are provided with a deployment signal by the RCM in conjunction with
the front airbags.

Diagnostic Help
1. The X-431 scan tool connects to the Data Link Connector (DLC) and communicates with the vehicle electronicmodules through the data network.
2. Confirm that the malfunction is current and carry-out the diagnostic tests and repair procedures.
3. If the DTC cannot be deleted, it is a current fault.
4. Use a digital multimeter to perform voltage readings on electronic systems.
5. Refer to any Technical Bulletins that may apply to the failure.
6. Visually inspect the related wiring harness.
7. Inspect and clean all Restraints Control Module (RCM) grounds that are related to DTC.
8. If numerous trouble codes were set, use a wiring schematic and look for any common ground circuits or voltage supply circuits that may apply to the DTC.
Intermittent DTC Troubleshooting
If the failure is intermittent perform the following:
•Check for loose connectors.
• Look for any chafed, pierced, pinched, or partially broken wires.
• Monitor the scan tool data relative to this circuit.
• Wiggle the related wiring harness and connectors while looking for an interrupted signal on the affected circuit.
• If possible, try to duplicate the conditions under which the DTC set.
• Look for the data to change or for the DTC to reset during the wiggle test.
• Look for broken, bent, pushed out or corroded terminals.
• Inspect the sensor and mounting area for any condition that would result in an incorrect signal, such as dam-
age, foreign material.
• A data recorder, and/or oscilloscope should be used to help diagnose intermittent conditions.
• Remove the Restraints Control Module (RCM) from the troubled vehicle and install in a new vehicle and test. If
the DTC cannot be deleted, the RCM is malfunctioning. If the DTC can be deleted, return the RCM to the origi-
nal vehicle.
Ground Inspection
Ground connections are very important to the proper operation of electrical and electronic circuits. Ground connec-
tions are often exposed to moisture, dirt and other corrosive elements. The corrosion (rust) can become an unwanted
resistance. This added resistance can alter the way a circuit works.
Electronically controlled circuits are very sensitive to proper grounding. A loose or corroded ground can drastically
affect an electronically controlled circuit. A poor or corroded ground can affect the circuit. Perform the following when
inspecting a ground connection:
1. Remove the ground bolt or screw.
2. Inspect all mating surface for tarnish, dirt, rust, etc.
3. Clean as required to assure good contact.
4. Reinstall bolt or screw securely.
5. Inspect for add-onaccessories which may be interfering with the ground circuit.
6. If several wires are crimped into one ground eyelet terminal, check for proper crimps. Make sure all of the wires are clean, securely fastened and providing a good ground path. If multiple wires are crimped to one eyelet, make
sure no excess wire insulation has been crimped creating a bad ground.
Diagnostic Tools
Diagnostic Scan Tool X-431
Read the following when connecting the X-431 scan tool:
•Connect the scan tool to the Data Link Connector (DLC) for communication with the vehicle.
• The DLC is located on the driver side compartment under the steering column (it is attached to the instrument
panel and accessible from the driver seat).
• The DLC is rectangular in design and capable of accommodating up to 16 terminals.
• The electrical connector has keying features to allow easy connection.

Use the airbag special load tools to diagnose airbag system faults:
•The airbag special load tools simulates airbag system components.
NOTE :
Using the airbag special load tools will help prevent other airbag DTCs from being set while troubleshooting the
system.
Digital Multimeter
Read the following when using the digital multimeter:
• Troubleshoot electrical problems and wiring systems.
• Use a multimeter for basic fault finding and bench testing.
• Use a multimeter to measure voltage, current and resistance.
