Tests carried out have revealed no reason for fault code Overheat to have taken place, however there is a known fault with the Air Pressure Switch which can result in an overheat fault code, this is caused by the air pressure switch not sitting back after a demand (not going back to open circuit between C-NO), further investigation may be required.
Upon completion of the fault diagnostics carry out final electrical safety tests and checks as per TOPs (C6).
