Jumper CHERY TIGGO 2009 Service Repair Manual

Downloaded from www.Manualslib.com manuals search engine Self-Learning Components
Perform the self-learning process when the following repairs have been made:
•Replaced the ECM
• ECM which was disconnected and reconnected
• Replaced the Accelerator Pedal
• Replaced the Electronic Throttle Control Actuator
Self-Learning Operating Procedure
Turn the ignition switch on for 10 seconds, then turn the ignition switch off. During the procedure, do not operate any
other components.
Self-Learning Condition
The self-learning condition as the Electronic Throttle Control Actuator Self-Learning Condition.
CAUTION:
Make sure that the Electronic Throttle Control Actuator self-learning process lasts for at least 10
seconds according to the Electronic Throttle Control Actuator self-learning condition. If the self-
learning process fails, the engine can’t be started or the EPC lamp will be on. If this condition
occurs, perform the Self-Learning operating again after the DTCs be erased in ECM.
Diagnostic Tools

Downloaded from www.Manualslib.com manuals search engine Use the scan tool to perform a System Test if one applies to a failing component. A co-pilot, data recorder, and/or
oscilloscope should be used to help diagnose intermittent conditions.
CAUTION:
Before starting repairs which do not require battery power:
•Turn ignition switch off.
• Disconnect the negative battery terminal.
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 effect 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.

Starter Motor Bench Test
Starter motor operation can be confirmed by performing
the following free-running bench test. This test can only
be performed with the starter motor removed from the
vehicle.1. Remove the starter motor from the vehicle (See Starter Motor Removal & Installation in Section 05
Starting and Charging).
2. Mount the starter motor securely in a soft-jawed bench vise. The vise jaws should be clamped on
the mounting flange of the starter motor (never
clamp on the starter motor by the field frame).
3. Connect a suitable volt-ampere tester and a 12 V battery to the starter motor in series, and set the
ammeter to the 100 A scale.
4. Install a jumper wire from the solenoid terminal to the solenoid battery terminal. The starter motor should oper- ate. If the starter motor fails to operate, replace the faulty starter motor assembly.
5. Adjust the carbon pile load of the tester to obtain the free running test voltage.
6. Note the reading on the ammeter and compare this reading to the free-running test maximum amperage draw.
7. If the ammeter reading exceeds the maximum amperage draw specification, replace the faulty starter motor assembly.
Starter Solenoid Test
This test can only be performed with the starter motor removed from the vehicle.
1. Remove the starter motor from the vehicle (See Starter Motor Removal & Installation in Section 05
Starting and Charging).
2. Disconnect the wire from the solenoid field coil ter- minal.
3. Check the solenoid for continuity between the sole- noid terminal and the solenoid field coil terminal
with a continuity tester. There should be continuity.
If there is continuity, go to Step 4. If not, replace
the faulty starter motor assembly.
4. Using a continuity tester, check for continuity between the solenoid terminal and the solenoid
case. There should be continuity. If not, replace the
faulty starter motor assembly.

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 Diagnostic Trouble Code (DTC) cannot be deleted, it is a current fault.
4. Use only 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 Engine Control Module (ECM) grounds that are related to the most current 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, or foreign material.
• A data recorder, and/or oscilloscope should be used to help diagnose intermittent conditions.
• Remove the Engine Control Module (ECM) from the troubled vehicle and install in a new vehicle and test. If
the DTC cannot be deleted, the ECM is malfunctioning. If the DTC can be deleted, return the ECM to the origi-
nal vehicle.

Transaxle Control Module (TCM) Electrical Harness Test Tool
If using a TCM electrical harness test tool, you can diagnose the TCM harness while the TCM is still connected.
•Measure sensor and solenoid resistance (always measure resistance with the power off).
• Measure the signal voltage of the TCM (always measure voltage with the power on).

Jumper Wires
•A jumper wire is used to create a temporary circuit.
Connect the jumper wire between the terminals of
a circuit to bypass a switch.
CAUTION:
Do not connect a jumper wire from the power
source line to a body ground. This may cause
burning or other damage to wiring harnesses
or electronic components.
Voltmeter
•The DC voltmeter is used to measure circuit volt-
age. A voltmeter with a range of 15 V or more is
used by connecting the positive (+) probe (red lead
wire) to the point where voltage will be measured
and the negative (-) probe (black lead wire) to a
body ground.
