DME 7.8 DME 7.8 0 · TID $05 Fuel tank ventilation system

DME 7.8 DME 7.8 0 TID $05 Fuel tank ventilation system For the fuel tank ventilation system, several tests are carried out consecutively but only one test value is output. This means that the subsequent test overwrites the preceding test value. When all tests have been carried out, $0D (micro-leak test) is dis- played. If a different CID is displayed, the test was interrupted - either because a fault was present or, for example, the EVAP canister was excessively loaded. In the case of decimal output the conversion factor = 0.00003876 The following CIDs can be displayed: ♦$00 Test not yet carried out ♦$0A Canister purge valve (leaking) ♦$0B Shut-off valve, EVAP canister (blocked) ♦$0C Major leak (pressure increase) ♦$0D Minor leak (leakage volumetric flow) ♦$0E Micro leak ♦$11 Shut-off valve, EVAP canister (pressure reduction) ♦$12 Major leak (pressure sensor) ♦$13 Major leak (pressure sensor) ♦$14 Tank vent valve (constantly open) TID $09 coolant thermostat Output of engine temperature Display between -48 °C and 143.25 °C In the case of decimal output, conversion factor = 1 Offset = -48 °C Decimal value displayed multiplied by 0.75 minus 48 °C gives the coolant temperature. Mode 7 The Diagnostic Trouble Codes of all non-shedded, officially rele- vant* faults are displayed in Mode 7. This mode has the same struc- ture as Mode 3. * Faults which switch on the Check Engine warning light Data output with a scan tool - 911 Carrera (996) 0-3.1 page 21 Printed in Germany – 8, 2002 dsc_FL78
