DME 7.8 DME 7.8 0 Note on adaptation The DME control module must perform a learning and adaptation routine for the throttle adjustment unit if: ♦The power supply to the DME control module is interrupted ♦The DME control module plugs are disconnected ♦A new DME control module is installed ♦The throttle adjustment unit is replaced ♦The DME is programmed. To do this: 1. Switch the ignition on for 1 minute without starting the engine. Do not actuate the accelerator pedal (for instance, make sure that there is not a carpet pressing on the pedal). 2. Switch off ignition for at least 10 seconds. The following conditions must also be observed, otherwise learning is not possible: ♦Vehicle is stationary ♦Battery positive voltage between 10 V and 16 V ♦Engine temperature between 5 °C and 100 °C ♦Intake air temperature between 10 °C and 100 °C Standard fault codes in accordance with ISO 15031 Diagnostic fault codes, which can be issued by the control module, are standardised in accordance with ISO 15031. This ISO standard is based on SAE J 2012. The fault code (DTC = Diagnostic Trouble Code) is always a 5-char- acter alphanumeric value, e.g. "P0100". The first character of the code (a letter) identifies the system that set the code. In all, there are four system types: ♦P for Powertrain (all OBD2 fault codes begin with this) ♦C for Chassis ♦B for Body ♦U for future systems. The P codes for powertrain are divided into two main categories in accordance with ISO 15031: 2470 INTRODUCTION 0-PEIN page 3 Printed in Germany – 14, 2003 PEIN2DME78
