Reading and Clearing Diagnostic Trouble Codes

On Board Diagnostic (OBD)

The Climatronic control module -J255- is controlled by an internal microprocessor with On Board Diagnostic (OBD) capability. If malfunctions, short or open circuits occur on monitored components, Diagnostic Trouble Codes (DTC) are stored in memory.

Perform On Board Diagnostic programs using VAS 5051/5052 Vehicle Diagnostic Testing and Information System in operating mode "Guided Fault Finding".
