Diagnostic trouble Code Memory [15]
Notes regarding Diagnostic trouble Code Memory
- To each fault (short circuit, open circuit etc) a certain numerical code has been assigned, i.e. Diagnostic Trouble Code (DTC). Additionally, current and intermittently appearing DTC's are differentiated from each other.
- When retrieving DTC's from the A/C pushbutton control module (N19), short circuits and open circuits can not be differentiated from each other in every case.
- If no DTC's are stored in DTC memory, but a complaint exists, it is possible that there may be a problem of incompatible tolerances between components. Since DTC memory can not read these tolerance variations, it is recommended that the entire system be completely checked, using the socket box and multimeter.
