CAUTION
The following five-step troubleshooting procedure is recommended.
Turn on all the components in the problem circuit to check the accuracy of the
customer's complaints. Note the symptoms.
Do not begin disassembly or testing until you have narrowed down the probable
causes.
1. Verify the customer's complaints
Use a test lamp or a voltmeter on circuits without solidstate units and use a test
lamp to check for voltage. A test lamp is made up of a 12-volt light bulb with a
pair of leads attached. After grounding one lead, touch the other lead to various
points along the circuit where voltage should be present.
When the bulb goes on, there is voltage at the point being tested.
SELF-POWERED TEST LAMP AND OHMMETER
Use a self-powered test lamp or an ohmmeter to check for continuity.
The ohmmeter shows how much resistance there is between two points along
a circuit. Low resistance means good continuity.
A number of circuits include solid-state modules, such as the Engine
Control Module(ECM), used with computer command control injection.
Voltage in these circuits should be tested only with a 10-megaohm or
higher impedance digital multimeter. Never use a test lamp on circuits
that contain solid state modules. Damage to the modules may result.
VOLTMETER AND TEST LAMP
Make a circuit test to check the diagnosis you made in step 2. Remember that a
logical, simple procedure is the key to efficient troubleshooting. Narrow down the
probable causes using the troubleshooting hints and system diagnosis charts.
Test for the most likely cause of failure first.
Try to make tests at points that are easily accessible.
3. Inspect the circuit/ component with the problem isolated
Once the problem is found, make the necessary repairs.
4. Repair the problem
Repeat the system check to be sure you have repaired the problem. If the
problem was a blown fuse, be sure to test all of the circuits on that fuse.
5. Make sure the circuit works
Locate the schematic for the problem circuit. Determine how the circuit is
supposed to work by tracing the current paths from the power source through
the system components to ground. If you do not understand how the circuit
should work, read the circuit operation text. Also check other circuits that share
with the problem circuit. The name of circuits that share the same fuse, ground,
or switch, for example, are referred to on each diagram. Try to operate any
shared circuits you did not check in step 1. If the shared circuit works, the
shared wiring is okay, and the cause must be within the wiring used only by the
problem circuit.
If several circuits fail at the same time, the fuse or ground is a likely cause.
2. Read and analyze the schematic diagram
TEST LAMP
A voltmeter can be used in place of a test lamp. While a test lamp shows
whether the voltage is present or not, a voltmeter indicates how much voltage
is present.
