HARNESS CONNECTOR INSPECTIONM1001003900201
CONNECTOR CONTINUITY AND VOLTAGE TEST
Required Special Tools:
MB991219: Test Harness Set
MD998459: Test Harness
Follow the steps below to avoid causing poor connector contact
and/or reduced waterproof performance of connectors when
checking continuity and/or voltage at waterproof connectors.
Never backtest probe a waterproof connector. Backprob-
ing a connector may cause the terminals to corrode, dete-
riorating circuit performance.
1. If the circuit to be checked is a closed state, use a special
tool like MD998459.
Forcing the test probe into the terminal may open the ter-
minal, causing intermittent or poor contact and creating an
open circuit.
2. If the connector is disconnected for checking and the facing
part is the female pin side, use an appropriate male terminal
for checking the contact pressure of connector pins (like
MB991219).
Do not simultaneously contact more than one terminal
with the test probe. Contacting two or more terminals at
the same time may damage a circuit, possibly to the point
of starting an electrical fire.
3. If the facing part is the male pin side, either carefully touch
the test probe to the pin so it does not accidently contact
other pins, or use an appropriate female terminal.
HOW TO DIAGNOSE
HOW TO DIAGNOSEM1001004300086
The most important point in troubleshooting is to
determine "Probable Cause." Once the probable
causes are determined, parts to be checked can be
limited to those associated with such probable
causes. The determination of the probable causes
must be based on a theory and be supported by facts
and must not be based on intuition only.

TROUBLESHOOTING STEPSM1001004400049
If an attempt is made to solve a problem without going through correct steps for troubleshooting, the symp-
toms could become more complicated, resulting in failure to determine the causes correctly and making
incorrect repairs. The four steps below should be followed in troubleshooting.
INFORMATION FOR DIAGNOSISM1001004500132
This manual contains the harness diagrams as well as the individual circuit drawings, operational explana-
tions, and troubleshooting hints for each component. The information is presented in the following manner:
1. Connector diagrams show the connector
positions, etc., on the actual vehicle as well as the
harness path.
2. Circuit diagrams show the configuration of the
circuit with all switches in their normal positions.
3. Operational explanations include circuit drawings
of current flow when the switch is operated and
how the component reacts.4. Troubleshooting hints include numerous
examples of problems which might occur, traced
backward in a common-sense manner to the
origin of the trouble. Problems whose origins may
not be found in this manner are pursued through
the various system circuits.
NOTE: Components of MPI, ETACS, etc. with ECU do not include 3 and 4 above. For this information, refer
to a relevant group which includes details of these components.
