INTRODUCTION - HOW TO TROUBLESHOOT THE VEHICLE 01-29
DETECTION PROCEDURE OF CIRCUITS

1. Basic checkup
(a). The measuring condition of the resistance of electrical components. 01
• If there are no special instruments, all the measuring operations of resistance
should be implemented in the environment with the temperature at 20℃ .
• The operating vehicle will generate high temperature, in which the resistance
value measured may exceed the range required. Therefore, the resistance
measure must be implemented after the engine becomes cool.

(b). Operating notes for connectors
• While removing the connector with a
snap close, press the connector slightly
along the connecting direction, and then
press the agraffe gently to open the snap
close.
• While removing the connector, hold it
and do not pull the harness.
• While connecting the connector, check
whether the connector is distorted,
damaged or in lack of pins.
• While connecting the connector with
a snap close, the sound "clatter" must
be heard to ensure that it is securely
connected.
• While checking the connector with a
multimeter, be sure to check the back of
the connector (the side of harness) with
the microprobe.
NOTICE:
• The waterproof connector cannot be checked in the back, so please check it after
connecting the auxiliary harness.
• Be careful to move the probe and do not damage the pins of the connector.

(c). Key points for checking connectors
While connecting the connector, please
check:
• Hold the connector, check the cut-in and
lock states (i.e. coherent state).
While the connector is disconnected,
please check:
• Pull the harness slightly to check whether
the pin is complete and curved and
whether the center harness is broken.
