CONNECTOR INSPECTION
When inspect each board and find the cause of the trouble, do not replace the board immediately but
check the following items.
• Abnormalies in related harnesses
• Looseness of the related connectors
• Bending or damage of connector pin and defective contact of any related connector pin
If any of the above is the cause of the trouble and the board is replaced with a new one, the new board
will be damaged.
Always replace the board after careful inspection.
When the trouble derives from a logic unit or board, measure the voltage and resistance of every part
involved in the substitution. Always disconnect the battery plug before measuring the resistance.
Important:
Disconnect the battery plug before connecting or disconnecting the logic unit.
Note:
When a logic unit is determined to be the cause of trouble as the result of troubleshooting,
always measure the applied voltage and resistance of each related portion when replacing.
(1)Setting Method
(a)Key switch OFF and battery plug disconnected.
(b)Connect the multimeter to the corresponding connector pin
Important:
As connection of the wrong connector pin may damage normal portions, make sure to confirm
the connector pin number.
