Galant L4-2.4L (4G69) (2004)
The MUT-III CAN bus diagnostics carries out the three checks below automatically, and then displays the current condition of the CAN bus lines
according to the check results.
1. MUT-III CAN bus diagnostics
The MUT-III diagnoses CAN bus lines in accordance with the following strategy.
1. Measuring voltage in CAN bus line
Diagnoses the power supply (such as wires of higher voltage than CAN communication line) and grounding (such as wires of lower voltage
than CAN communication line) of CAN bus lines for short circuit by measuring the voltages between the CAN_L line or H line and body
ground.
