Malfunction Criteria
P1
Map 4 Malfunction criteria limit for evaporation diagnosis
Time (evpdset) vs. Fuel level
0 L (0 US gal, 0 Imp gal)
10 L (2.64 US gal, 2.2 Imp gal)
30 L (7.93 US gal, 6.6 Imp gal)
50 L (13.21 US gal, 11.0 Imp gal)
60 L (15.85 US gal, 13.2 Imp gal)
70 L (18.49 US gal, 15.4 Imp gal)
80 L (21.14 US gal, 17.6 Imp gal)
Time Needed for Diagnosis: 65 — 516 seconds
Malfunction Indicator Light Illumination: Illuminates when malfunction occurs in two continuous driving
cycles.
6. DTC CLEAR CONDITION
• When the OK idling cycle is completed 40 times in a row
• When "Clear Memory" is performed
7. MALFUNCTION INDICATOR LIGHT CLEAR CONDITIONS
• When the OK driving cycle is completed three times in a row
• When "Clear Memory" is performed
8. FAIL SAFE
None
9. ECM OPERATION AT DTC SETTING
• Memorize the freeze frame data. (For test mode $02)
• Memorize the diagnostic value and trouble standard value. (For test mode $06)
