NOTE:
- When the ABS/EDL control module recognizes that a wheel is spinning, the ABS/EDL control module generates the rough terrain signal. When the Engine Control Module (ECM) recognizes the rough terrain signal, combustion misfire recognition is switched off in the Engine Control Module (ECM).
- Only check the rough terrain signal if the malfunction "18014 (P1606) rough terrain info/engine torque from ABS cont. mod. Electrical malfunction in circuit" is stored DTC memory. It is possible that the malfunction "Combustion misfire" is also stored in DTC memory as a side effect and it can be disregarded.
- The rough terrain signal is transferred from the ABS/EDL control module to the Engine Control Module (ECM) via CAN-bus. Check data exchange between Engine Control Module (ECM) and other CAN capable control modules.
