What does Scania TMS fault code 274 mean?
The fault code is activated when there is a high torque in the rotation motor, but no changes to the position have been registered.
What causes Scania DTC 274?
- The rotation of the electric motor is prevented in the clutch actuator. - Rotation is prevented in the gear box. - Rotation is prevented in bearings. - Conversion of rotation to linear movement is prevented in the ball screw. - Linear movement is prevented in the preloaded plunger or pushrod.
How does the system react?
- A yellow warning indication is displayed. - If the vehicle is stationary when the fault occurs: neutral position is activated, which prevents the vehicle from being driven further. - If the vehicle is driving when the fault occurs: the gear continues in locked position. Neutral (N) is activated when the vehicle slows to a stop. This prevents the vehicle from being driven further.
