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 (minor 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. 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) ♦$11 Shut-off valve, EVAP canister (pressure reduction) ♦$12 Major leak (pressure sensor) ♦$13 Major leak (pressure sensor) ♦$14 Tank vent valve (constantly open) Mode 7 The fault codes of all non-shedded, officially relevant* faults are dis- played in Mode 7. This mode has the same structure as Mode 3. * Faults which switch on the Check Engine warning light Mode 9 The following vehicle information is displayed in Mode 9: ♦Vehicle Identification Number ♦Programme status (Calibration Identification Number) ♦Control unit checksum (Calibration Verification Number) Data output with a scan tool 0-3 page 21 Printed in Germany – 8, 2002 dsc_dm78
