24 1 AMBIENT TEMPERATURE SENSOR - OUT OF
RANGE LOW System is in platform mode;
MACHINE SETUP -> TEMP CUTOUT = yes;
Low Temperature Cutout Sensor reads less than or
equal to -50 °C. Ambient Temperature sensor reading > -50 °C
THEN speed restrictions removed after controls
are initialized
24 2 AMBIENT TEMPERATURE SENSOR - OUT OF
RANGE HIGH System is in platform mode;
MACHINE SETUP -> TEMP CUTOUT = yes;
Low Temperature Cutout Sensor reads greater than
or equal to 85° C. Ambient Temperature sensor reading > -50 °C ;
Speed restrictions removed after controls are ini-
tialized
25 3 DRIVE PREVENTED - CHARGER CONNECTED MACHINE SETUP => CHARGER INTERLOCK = DRIVE
ONLY; Trigger conditions not true;
Restrictions remove after CntIni
25 9 MODEL CHANGED - HYDRAULICS SUSPENDED -
CYCLE EMS The MACHINE SETUP => MODEL has changed Power cycle
25 14 BOOM PREVENTED - DRIVE SELECTED MACHINE SETUP => FUNCTION CUTOUT = BOOM
CUTOUT;
Drive or Steer is already engaged;
The boom is Above Elevation;
The operator is attempting to activate one of the
boom functions DTC 2514 supersedes DTC 2518 if
drive/steer and boom functions are both active
when machine transitions from Below Elevation to
Above Elevation. Not all of the trigger conditions are met
25 16 DRIVE PREVENTED - ABOVE ELEVATION MACHINE SETUP => FUNCTION CUTOUT = DRIVE
CUTOUT;
The boom is Above Elevation;
The operator is attempting to activate Drive or
Steer; Not all of the trigger conditions are met
25 18 DRIVE PREVENTED – BOOM SELECTED MACHINE SETUP => FUNCTION CUTOUT = DRIVE
CUTOUT;
The boom is Above Elevation;
The operator is attempting to activate Drive or
Steer; Not all of the trigger conditions are met
25 38 FUNCTION PREVENTED – CHARGER CON-
NECTED MACHINE SETUP => CHARGER INTERLOCK = CUT-
OUT ALL;
MTM reports charger connected;
UGM determines that machine is Enabled, and a
function command was attempted. Not all of the trigger conditions are met;
Restricts removed after CntIni
25 48 SYSTEM TEST MODE ACTIVE UGM determines that System Test Mode is active Power cycled
25 49 DRIVE & BOOM PREVENTED - SOFT TOUCH
ACTIVE MACHINE SETUP

SOFT TOUCH = YES;
Machine is in Platform Mode;
Soft Touch State = Enabled
Not all of the trigger conditions are met
25 63 SKYGUARD SWITCH – DISAGREEMENT MACHINE SETUP

SKYGUARD ≠ NO;
Machine is in Platform Mode; [(SkyGuard input #1
Platform Module J7-18) ≠ (SkyGuard input #2 Plat-
form Module J1-23)] > 160ms
[{SkyGuard inputs (Platform Module J7-18 =
High) and (Platform Module J1-23 = High)} and
(Footswitch State = Not Depressed)]
25 64 DRIVE PREVENTED – LEFT BRAKE NOT RELEAS-
ING Module detects brakes have not released because
EB coil is damaged Power cycle
25 65 DRIVE PREVENTED – RIGHT BRAKE NOT
RELEASING Module detects brakes have not released because
EB coil is damaged Power cycle
25 68 TEMPERATURE CUTOUT ACTIVE – AMBIENT
TEMPERATURE TOO LOW Low Temperature Cutout = Active Low Temperature Cutout = Inactive; speed
restrictions removed after controls are initialized
