Aftertreatment System Regeneration
Switches
NOTE: See Chapter 11 for detailed information
about the operation of the regeneration (regen)
switches and the aftertreatment system (ATS).
The regen switch ( Fig. 5.16 ), located on the dash, is
used to initiate a parked regen.
When activated, the optional regen-inhibit switch
(
Fig. 5.17 ) stops a regen in progress and prevents
the start of a regen until the switch is no longer ac-
tive.
Axle Switches
NOTE: See Chapter 15 for detailed information
about axle switch functions.
Differential Lock Switch
The differential lock provides maximum traction for
slippery conditions by forcing the wheels on each
drive axle governed by the switch to rotate together.
NOTICE
The differential lock should only be engaged
when the vehicle is moving slowly at low throttle.
Engagement at high speed or power can damage
the axle(s).
See Fig. 5.18 for the differential lock switch on a ve-
hicle with a single drive axle.
