CONTROL UNIT CIRCUIT TESTNJGI0005S0306System Description: When the switch is ON, the control unit lights
up the lamp.

1 Switch Switch ON Battery voltage Lower than battery voltage Approx. 8 (Example)
Switch OFF Approx. 0 Approx. 0
2 Lamp Switch ON Battery voltage Approx. 0 (Inoperative lamp)
Switch OFF Approx. 0 Approx. 0
The voltage value is based on the body ground.
* : If high resistance exists in the switch side circuit (caused by a single strand), terminal 1 does not detect battery voltage. Control unit
does not detect the switch is ON even if the switch does not turn ON. Therefore, the control unit does not supply power to light up the
lamp.

NOTICE:
Trouble diagnoses indicate work procedures required to diagnose
problems effectively. Observe the following instructions before
diagnosing.
1)Before performing trouble diagnoses, read the ªPrelimi-
nary Checkº, the ªSymptom Chartº or the ªWork Flowº.
2)After repairs, re-check that the problem has been com-
pletely eliminated.
3)Refer to Component Parts and Harness Connector Loca-
tion for the Systems described in each section for
identification/location of components and harness con-
nectors.
4)Refer to the Circuit Diagram for quick pinpoint check.
If you need to check circuit continuity between harness
connectors in more detail, such as when a sub-harness is
used, refer to Wiring Diagram in each individual section
and Harness Layout in EL section for identification of har-
ness connectors.
5)When checking circuit continuity, ignition switch should
be OFF.
6)Before checking voltage at connectors, check battery volt-
age.
7)After accomplishing the Diagnostic Procedures and Elec-
trical Components Inspection, make sure that all harness
connectors are reconnected as they were.

1)Work and diagnostic procedure
Start to diagnose a problem using procedures indicated in
enclosed test groups.
2)Questions and required results
Questions and required results are indicated in bold type in test
group.
The meaning of are as follows:
a. Battery voltage®11 - 14V or approximately 12V
b. Voltage: Approximately 0V®Less than 1V
3)Symbol used in illustration
Symbols included in illustrations refer to measurements or pro-
cedures. Before diagnosing a problem, familiarize yourself with
each symbol. Refer to ªCONNECTOR SYMBOLSº (GI-16) and
ªKey to Symbols Signifying Measurements or Proceduresº (GI-
33).
4)Action items
Next action for each test group is indicated based on result of
each question. Test group number is shown in the left upper
portion of each test group.
