..3 Circuit Fault Diagnosis..3- Circuit Fault Diagnosis..3- Diagnostic Procedure Refer to the following procedure for the circuit fault diagnosis:. Confirm Fault To do the proper repair, confirm the fault symptoms described by the customer firstly. Inspect the relevant component carefully to confirm the fault symptoms and make record. DO NOT disassemble the component before confirmation of the fault scope and causes.. Read Wiring Diagram and Analyze Causes Make a complete analysis and judgement on the fault components from power supply to grounding according to the sub-system wiring diagram and determine the repair solution. If it cannot be determined, please read the system description in the Description and Operation section in the repair manual to understand the working principle. And inspect other circuits that has common part with the fault circuit, for example, the fuse, grounding, switch, etc. Inspect the circuit not covered in step. If other components in the common circuit work properly, it means the fault exists in its own circuit. Otherwise, the fuse or grounding may have faults. 3. Inspect Circuits and Components Always use the wiring diagram together with repair manual and refer to the diagnostic procedure for the relevant circuits or components in the repair manual. For the circuit with a control module, fully use diagnostic tools to do the test. Effective diagnosis should be a logical and reasonable operation. Fully use the diagnostic procedures in the repair manual and start the inspection from the causes and the components with easiest inspection way. 4. Repair Fault Repair the fault. Refer to the wiring diagram and the description for fault treatment in repair manual. For example, the diagnostic procedure for poor grounding and the wiring harness connector treatment. 5. Confirm Circuit Working Condition After repair, all functions should be reinspected to confirm the fault repaired. For the fuse blown fault, Inspect all the relevant circuits using this fuse. Diagnostic Tools. Voltmeter and Test Lamp M0300 Use test lamp or voltmeter to inspect the circuit status. Test lamp comprises a pair of wiring harnesses and a V bulb. When inspecting, connect one wiring harness to the ground and the other one to the certain measurement point. If the bulb is lit, it means the measurement point has power supply. Warning: DO NOT use test lamp to inspect the control module voltage. Otherwise it could damage the interior circuit inside the control module. Please use a voltmeter with 0 MΩ or higher internal resistance (for example, to test the ECM voltage). Voltmeter has the same connection method as the test lamp, but voltmeter can display the voltage value of the circuit. Use a voltmeter with high resistance to test the voltage. If the circuit has poor connection, the voltmeter may show the normal value, but the voltage cannot drive the load successfully.
..3- Circuit Fault Diagnosis..3-. Self-powered Test Lamp and Ohmmeter M0300 Use test lamp with own V power supply or ohmmeter to inspect the circuit for continuity. Test lamp comprises a bulb, battery and a pair of wiring harnesses. The bulb will be lit when the two wiring harnesses are connected. Before testing, disconnect the negative battery cable and pull out the fuse of the circuit. To test the circuit for continuity, connect two wiring harnesses to the two measurement points. If the bulb is lit, it means the circuit is normal. Warning: DO NOT use self-powered test lamp to inspect the control module. Otherwise, it could damage the interior circuit inside the control module. Please use a ohmmeter with 0 MΩ or higher internal resistance. Ohmmeter has the same usage method as voltmeter, but ohmmeter can show the resistance value. The lower resistance, the better continuity. 3. Jumper Wire with Fuse Use jumper wire to test a broken point for open loop circuit (circuit open). The jumper wire is a tool that should be in tandem with the circuit. Warning: To protect the circuit to be inspected, DO NOT use the fuse higher than the rated capacity of circuit to inspect relevant circuits. DO NOT use the jumper wire as the input or output signal when a control module such as ECM or TCM is in the circuit. Otherwise it could damage the circuit interior inside the control module. Fault Testing. Voltage Testing 5A 0.5RD +B E00 Switch E00 0.5G C00 Solenoid I/P Fuse and Relay Box Voltmeter Test Lamp 5A M03004 Voltage testing is to test the voltage at a certain point. When testing a certain connector terminal, insert the positive probe into the wiring harness from the connector back without assembling wiring harness connector. M03003
..3-3 Circuit Fault Diagnosis..3-3 When testing the voltage with test lamp or voltmeter, connect the negative of testing tools to battery negative. Connect the other wiring harness of the test lamp or the positive probe of the voltmeter to the test position. 3 If a voltmeter is used and voltage display lower V above compared to the rated value, it means a circuit fault. It means a circuit fault if a test lamp is used and lamp is not lit.. Power Testing 3. Short Circuit Testing 5A 0.5RD +B E00 Switch I/P Fuse and Relay Box Voltmeter Test Lamp E00 0.5G Switch C00 Solenoid M03006 M03005 Disconnect the negative battery cable. Connect one wiring harness of the selfpowered test lamp or the probe of the ohmmeter to the test component. If using ohmmeter, please connect the two probes each other and use reset button to adjust the ohmmeter to zero. 3 Connect the other wiring harness of the test lamp or probe of the ohmmeter to the other side of the test load. 4 If the bulb is lit, it means the circuit is normal. If an ohmmeter is used and the resistance value is very low or close to 0 Ω, it means the component has good continuity. Disconnect negative battery cable. Connect one wiring harness of the selfpowered test lamp or one probe of the ohmmeter to the output terminal of the fuse. 3 Connect the other wiring harness of the test lamp or other probe of the ohmmeter to the grounding. 4 Disconnect all the electrical loads to the fuse. CAUTION: If not disconnecting all the electrical loads to the fuse, when testing the low resistance circuit like lights, the ohmmeter will always display the low value. This will cause wrong judgement. 5 Do the careful inspection from the place closest to the fuse. 6 If the bulb is lit or ohmmeter has value display less than 5 Ω, it means the short circuit to the ground.
..3-4 4. Voltage Drop Testing Circuit Fault Diagnosis Repair Tools..3-4 5A +B I/P Fuse and Relay Box Voltmeter 0.5RD E00 Switch E00 0.5G M03008 C00 Solenoid. 5 KΩ Rheostat M03007 This is a test to inspect the voltage drop along the wiring harness, connector or switch. Connect the positive probe of the voltmeter to one end of the circuit close to the battery (connector or switch side). Connect the negative probe to the other end of the circuit (the other side of connector or switch). 3 Switch on or off to make the circuit work. 4 The voltmeter will display the voltage difference between the two test points. 5 If the voltage difference is more than 0. V (less than 50 mv for 5 V voltage circuit), it means a circuit fault. Inspect for loose, oxidized or corrosive circuit. M03009 It can simulate each ohm-type sensor signal, like coolant temperature sensor, air intake pressure and temperature sensor and the like. And help make quick judgement on the performance of the component.
..3-5 Circuit Fault Diagnosis..3-5. LED Test Lamp 4. Probe M0300 Bidirectional two-color LED lamp can change its color when exchanging the positive and negative. This feature can be used to test the PWM control signals of Hall sensor. 3. Airbag Test Tool M030 When testing a system component, insert this tool into the connector from the back and it is unnecessary to break the wiring harness to reduce man-made fault. 5. Terminal Repair Tool M030 Before installing a new airbag after airbag system has faults or vehicle accident, install this tool to the airbag system, and use diagnostic tools to confirm the airbag system work properly. After that, install the new airbag. This process can guarantee a safe airbag operation. M0303 When maintaining and repairing certain terminal, use this tool to separate them from the connector.
