HEA-898

Test driving

Testing the heater unit

Note! Diagnostic trouble code (DTC) HEA-898 is set in the control module to ensure that the heater is tested at the factory before the car is delivered to the customer. In other words this diagnostic trouble code (DTC) cannot be set by the control module itself, only by the manufacturer. The diagnostic trouble code (DTC) is automatically erased at the factory when the unit is tested. When the unit is installed as a replacement part the diagnostic trouble code (DTC) must be erased manually after the heater has been tested in the car.
