WARNING: This page is about a different variant/trim than selected.
- Connect the M-MDS to the DLC-2.
- Start and warm up the engine.
- Monitor the engine coolant temperature with the M-MDS.
- Measure the voltage at terminal A of the fan control module connector (2 terminals) as shown in the table.
- If not within the specification, inspect the input signals from the following parts.
- Cylinder Head Temperature (CHT) sensor
- Refrigerant pressure switch (middle)
