Electrical Components Controlled by Heating System, Checking

From the Climatronic control module (J255)

The vehicle electrical components that are activated by heater are identical to those on vehicles with A/C. The electrical test for the various components is therefore performed in the same way as the test for these components on vehicles with an A/C system. Refer to Vehicle diagnosis, testing and information system (VAS5051B) in the "Guided Fault Finding" function.

These components are activated and function the same way on a vehicle without A/C (vehicles with a heater only). Refer to => [ Components Actuated by A/C System, Electrical Test ] Components Actuated by A/C System, Electrical Test and Vehicle diagnosis, testing and information system (VAS5051B) in the "Guided Fault Finding" function.

• Various vehicle electrical components (for example, Heated Rear Window (Z1) and heated seats) that do not belong to the heater are activated by the Climatronic control module (J255). Check the electrical components as described in Guided Fault Finding (it is the same on both vehicle with and without A/C). Refer to => [ Components Actuated by A/C System, Electrical Test ] Components Actuated by A/C System, Electrical Test and Vehicle diagnosis, testing and information system (VAS5051B) in the "Guided Fault Finding" function.
