187 – AL CAN1 Error Passive

Yellow alarm.
Associated parameter 2.0500.687

Cause

Corrective action

CAN controller 1 has indicated a
warning. Bus users (ECU, SAM
or EMU) are faulty.

Check operation of bus stations and cabling.

188 – AL CAN2 Bus Off

Yellow alarm.
Associated parameter 2.0500.688

Cause

Corrective action

CAN controller 2 is in “Bus Off”
status. Automatic switching to
CAN bus 1. Bus users (ECU,
SAM or EMU) faulty.

Check operation of bus stations and cabling.

189 – AL CAN2 Error Passive

Yellow alarm.
Associated parameter 2.0500.689

Cause

Corrective action

CAN controller 2 has indicated a
warning. Possible causes may
be, e.g. missing node, minor
malfunctions or temporary bus
overload.

Check operation of bus stations and cabling.

190 – AL EMU Parameter Not Supported

Red alarm.
Associated parameter 2.0500.690

Cause

Corrective action

EMU parameters are not
supported.

Contact Service (configuration fault).

201 – SD T-Coolant

Red alarm. Engine shutdown.
Associated parameter 1.8004.570

Cause

Corrective action

Coolant temperature sensor at
engine outlet defective, short
circuit or wire break.

Check sensor and cabling (B6.1), replace as necessary. Fault is
rectified following engine restart.
