Volvo ECS User Manual

ECS Gen. 1
Interlock mode
If an ECS fault occurs, the ECU will put the system into
ʻinterlockʼ or ʻblockedʼ mode. In this mode, the voltage
supplies to the solenoid valve blocks are removed, so
automatic height adjustment does not work.
A quick method to find out if the system is in interlock mode
(on trucks with a lifting rear axle):
- put the control switch (1) in normal driving position - AUT
- move the regulator switch (3) to raise or lower position
- if the axle is raised or lowered, the system is in interlock
mode
Is the system in
interlock mode ?
