deactivated

-

VSC system deactivated

73-15

If a drawn vehicle with EBS sends a CAN
message to the ECU of the prime mover,
indicating that the "serious drawn vehicle failure"
needs to be activated on DIP, this fault code will
be stored in the prime mover ECU.

74-11

Internal fault in the VSC module (F702)

-

VSC system deactivated

74-12

Incorrect parameters of the VSC module (F702)

-

VSC system deactivated

74-13

Incorrect software version in the VSC module
(F702) or rear axle modulator (D978) for the VSC
control

-

VSC system deactivated

74-14

The EBS unit detects a fault in the CAN message
from the VSC module (F702)

-

VSC system deactivated

74-15

Internal fault in the VSC module (F702)

-

VSC system deactivated

74-16

Sensor fault in the VSC module (F702)

-

VSC system deactivated

74-18

Insufficient supply voltage on VSC module (F702)
due to:
-

contact resistance or poor connection

-

VSC system deactivated

74-49

Unacceptable information from steering angle
sensor (F701) due to:
-

incorrect mechanical adjustment of steering
gear

-

damaged/defective steering angle sensor

-

VSC system deactivated

74-64

CAN communication problem of the EBS unit with
the VSC module (F702) via pins B2 and B5 due
to:
-

short circuit between pin B2 and pin B5 of
the EBS unit

-

VSC system deactivated

74-77

The EBS unit has not received a CAN message
from the VSC module (F702) and steering angle
sensor (F701) within a specified period of time
due to:
-

interruption on pin B2 and/or B5 of the EBS
unit

-

short circuit to earth on pin B5 of the EBS
unit

-

short circuit to supply on pin B2 and/or pin
B5 of the EBS unit

-

VSC system deactivated

74-81

Sensor information from VSC module (F702)
does not correspond with the steering
performance of the vehicle due to:
-

wrong installation of VSC module

-

VSC system deactivated

74-82
