1 | Fault code | |
2 | Fault memory and actuation of CHECK ENGINE (MIL) | After two consecutive journeys with fault |
3 | Monitoring time and frequency of testing | Continuous |
4 | Checked signal or status | Comparison of recognized gear and shifted gear (calculated gear ratio) negative at least 6 times. |
5 | Test conditions | – 2nd, 3rd, 4th or 5th gear recognized – Engine speed > 400 rpm – Output shaft speed > 150 rpm – No shift process |
6 | | The gear ratios are calculated from the following values: Speed signal n2, speed signal n3 and output shaft speed (determined via rear wheel speed). Faults are recognized by the ETC control module and conveyed to the engine control module (ME-SFI) via the CAN data bus. The engine control module (ME-SFI) carries out fault memory and actuation of CHECK ENGINE (MIL). Also read out the ETC fault memory, fault code 55. |
