Troubleshooting.

Troubleshooting Tool.

1. Jumper Wire.

Jumper wires are used to create temporary circuits, and connected between circuit terminals to bypass switches.

Warning:

Do not connect jumper wire from power source end to body ground, otherwise, wire harness or electrical components may be damaged.

2. Voltmeter.

Voltmeter is used to measure the circuit voltage. Measurement range should be higher than 15 V. Voltage is measured by connecting the positive probe (red) of voltmeter to positive lead of part to be tested and the negative probe (black) to the negative lead or body ground.

3. Ohmmeter.

Ohmmeter is used to measure the resistance between two points in a circuit, or to check the circuit for open or short.

Warning:

When applying voltage to the circuit, do not connect the ohmmeter to circuit, otherwise the measurement data may be inaccurate or even cause damage to ohmmeter.

Electrical Malfunction Troubleshooting.

1. Wire Harness Troubleshooting.

Following 6 steps help to diagnose and troubleshoot wire harnesses. Be sure to check any non-genuine components added to the vehicle before performing any diagnosis. If the vehicle is equipped with such components, disconnect them to confirm that the added components are not the cause of fault.

To troubleshoot the wire harness, perform the following steps:

(1) Confirm problem.

(2) Look for any related symptoms (by checking components in same circuit).

(3) Analyze symptoms (use circuit diagram to determine circuit layout, areas most likely to fail, and areas to proceed with diagnosis).

(4) Isolate the failure area.

(5) Repair the failure area.

(6) Check if it is working properly (in this step, check if all items of repairing circuit are working properly).

2. Voltage Check.

(1) Determine conditions in which voltage is present at the check point.

Example:

[A] – Ignition switch ON.

[B] – Ignition switch and switch ON.

(2) Using a voltmeter, connect the negative probe (black) to a good ground point or negative battery terminal, and the positive probe (red) to the connector or component terminal.

This check can be done with a test light instead of a voltmeter.

3. Continuity Check.

(1) Turn off all electrical appliance and ignition switch, disconnect the negative battery cable.

(2) Disconnect the circuit to be tested.

(3) Connect the two probes of ohmmeter to both ends of tested circuit, and check the circuit continuity (lower resistance indicates better circuit continuity).

If the circuit has diodes, reverse the two probes and check again.

When contacting the negative probe (black) to the diode positive side, and the positive probe (red) to the negative side, there should be continuity; When contacting the two probes in reverse, there should be no continuity.

4. Short Circuit Check.

(1) Measure and record battery voltage.

(2) Pull out the fuse of tested circuit or disconnect the power source end of tested circuit.

(3) Connect the positive probe of voltmeter (red) to the positive battery terminal, and negative probe (black) to power source end of circuit.

(4) Check the voltage value shown on voltmeter. If voltage value of battery is displayed, it indicates that the test circuit short to the ground.

(5) This check can be done with a test light instead of a voltmeter.

5. Wire Harness Repair.

Caution:

Before repairing, measure the length of wire to be repaired and select a suitable substitute wire.
If there are multiple wires to be repaired, separate the repaired parts.

(1) Strip 0.5 inch insulation layer from repair wire and substitute wire.

(2) Use heat shrink sleeve to connect the original wire and substitute wire, and compress the metal core of heat shrink sleeve with a tool to securely connect the original wire and substitute wire.

(3) Keep the outer layer of the heat shrink sleeve in a good heat-shrinking state.

(4) Wrap the repaired wires with insulating tape.

6. Fuse Replacement.

Caution:

After replacing the fuse, perform a power on test. If the fuse is blown again, check the corresponding circuit for short. If any electrical equipment or additional equipment that exceeds the rated current is installed, replace the fuse with a higher current.

(1) Turn off all electrical equipment and ignition switch before repair.

(2) Remove the blown fuse with fuse puller.

(3) Replace with a new fuse with same specification.

7. Electrical Components.

(1) Battery cable.

Disconnect negative battery cable (arrow) before repairing electrical components.

(2) Sensors, switch and relay.

Do not drop or knock sensors, switches or relays during repair, to avoid damaging components.

Caution:

Use relay with same specifications as the original relay during replacement.

(3) Connector.

– Disconnect the connector.

To pull apart the connectors, pull on the connector itself, and press the connector clip to disconnect.

Caution:

When disconnecting connectors, do not forcibly pull the wire harness to avoid damaging parts.

There are many ways to secure the connector clip. The following figure shows the common disconnection method.

– Install the connector.

When the connector is installed in place, a “click” is heard.

– Replace the connector terminal.

As shown in figure (1), insert appropriate tool into the terminal to lift fixing clip, and then pull out terminal from back side. During installing, push the terminal from back of connector to ensure that fixing clip is installed in place, as shown in figure (2).
