1 | Fault code ( Readout on generic scan tool) | P201D Cylinder 1 (Y62y1) (P0201) P2021 Cylinder 2 (Y62y2) (P0202) P201F Cylinder 3 (Y62y3) (P0203) P2022 Cylinder 4 (Y62y4) (P0204) P201E Cylinder 5 (Y62y5) (P0205) P2020 Cylinder 6 (Y62y6) (P0206) P208A Cylinder 7 (Y62y7) (P0207) P20Bb Cylinder 8 (Y62y8) (P0208) P20B9 Cylinder 9 (Y62y9) (P0209) P20BC Cylinder 10 (Y62y10) (P0210) P208B Cylinder 11 (Y62y11) (P0211) P20Ba Cylinder 12 (Y62y12) (P0212) |
2 | Fault storage Actuation of engine diagnosis indicator lamp (EURO4) or CHECK ENGINE (MIL) malfunction indicator lamp | after expiry of test duration and fault following two successive driving cycles with faults |
3 | Checking frequency | Continuous |
4 | Checked signal or status | Current/voltage test on respective fuel injector |
5 | Fault setting conditions Limit values Short circuit to ground Short circuit to + 12V Open circuit in wiring Checking duration |
Voltage < 2.5 V Current > 4.2 A No voltage on fuel injection valve Approx. 4 - 8 V on under no load output of the ME control unit approx. 1 seconds |
6 | Check prerequisites | Battery voltage 8 to 17 volts |
7 | | The actuation of each fuel injector is tested for line interruption and short circuit (to ground or battery voltage). A short circuit to ground and a line discontinuity will be recognized when the output stages are locked, while a short circuit to the battery voltage is recognized when the output stages are conducting. The output stage is immediately no longer activated when a fault arises. |
8 | | In the event of a short circuit to ground, the corresponding fuel injector is continuously open. |
