DME 7.8 DME 7.80 ♦Uniformly standardised codes: P0XXX and P2XXX; these are the same for all manufacturers ♦Manufacturer codes: P1XXX and P3XXX; only the first three char- acters are standardised here (example: P13XX for ignition sys- tem diagnosis or misfire detection); the last two digits can be selected freely by the manufacturer. Only the P codes are required for OBD II. The standardised codes are subdivided as follows: P0001 to P0299 Fuel and air proportioning P03xx Ignition system and misfire detection P04xx Additional exhaust regulations P05xx Speed and idle speed control P06xx Computer and output signals P0700 to P0999 Transmission P2000 to P2299 Fuel and air proportioning P23XX Ignition system and misfire detection P24XX Additional exhaust regulations P25XX Additional input signals P26XX Computer and output signals P27XX Transmission P28XX Reserved P29XX Fuel and air proportioning Definition of terms Warm-up cycle Warm-up cycle means the warm-up phase of the engine. To satisfy the 'warm-up cycle' condition, the engine temperature must not exceed a certain value during starting (presently 44 °C). The operat- ing phase of the engine must last long enough to achieve a certain temperature increase (presently 21 °K, although the temperature reached must be at least 54°C). The warm-up cycle condition is required in order to decrement the deletion counter for faults that are registered as "remedied" (on this see the paragraph 'Remedying faults'). 0-PEIN page 4 2470 INTRODUCTION PEIN2DME78 Printed in Germany – 14, 2003
