Notes for checking error symptoms:

• Check normal units as well as error symptoms.

  • Example: Circuit between ECM and the combination meter is judged normal if the customer indicates tachometer functions normally.

• Indication of the combination meter is important to detect the root cause because it is the most obvious to the customer, and it performs CAN communication with many units.
