Hva betyr feilkoden?
The throttle unit (ETM) has noticed that the ECM signals cruise control as on while the brake light switch is pressed, or that the throttle unit has a fault that blocks cruise control. The ECM then stores the code, which can come together with other fault codes.
Mulige årsaker
- Open circuit, short-circuit to voltage or short-circuit to ground in the brake light switch signal cable between the ECM and the throttle unit
- Defective engine control module
Hva du kan gjøre
- 1First troubleshoot fault codes ECM-9400 and/or ECM-914F if they are stored, as they should be traced first
- 2Use the frozen values and counters of the fault code. If the fault has occurred often recently, it is easier to recreate it during troubleshooting
- 3Use a multimeter to check that the brake light switch signal cable has no open circuit and is not short-circuited to voltage or ground
- 4Erase the code and reset: ignition off for three minutes, on and off again, then three more. Add two minutes if the cooling fan has been running.
- 5If the fault remains, the engine control module may be defective, and a workshop should check it
Symptomer du kan merke3
- The accelerator pedal is ignored when the brake pedal is pressed
- The cruise control cannot be activated
- The ETS warning lamp lights, on C70 and S/V70 -2000 only
Hva feilen kan påvirke3
- The throttle closes when braking, and pedal input is ignored while the brake is pressed
- The cruise control is switched off during the driving cycle when the fault was detected, and it works again the next time the car starts if the fault is gone
- While the fault is active, the throttle tracks the pedal and cruise control is blocked from engaging
