SECTION 7 - DIAGNOSTIC TROUBLE CODES
7-12 3121788
33406 LIFT UP VALVE – SHORT TO
GROUND
None 3_3 • Disable Output
• Lift Up State = PREVENTED Short to Ground was detected on LIFT_UP_VLV X
33407 LIFT DOWN VALVE – SHORT TO
GROUND
None 3_3 • Disable Highside Output
• Open Lowside Output
• Lift Down State = PREVENTED
• Lift Up State = PREVENTED Short to Ground was detected on LIFT_DN_VLV
• This fault covers both if the Highside Output
or if the Lowside Output is shorted to Ground.
• If Lowside is shorted to Ground, the feedback
will read 0 mA while the Highside is com-
manding a PWM… this shall lead to this
fault being triggered.
X
335 LIFT DOWN VALVE – SHORT TO
BATTERY None 3_3 • Disable Highside Output
• Open Lowside Output
• Lift Down State = PREVENTED
• Lift Up State = PREVENTED Short to Battery was detected on LIFT_DN_VLV
• This fault covers both if the Highside Output
or if the Lowside Output is shorted to Battery.
X
33537 AUXILIARY LIFT DOWN VALVE -
SHORT TO GROUND
None 3_3 • Disable Highside Output
• Open Lowside Output
• LiftDownState = PREVENTED
• LiftUpState = PREVENTED Short to Ground was detected on
LIFT_DN_VLV_2 AND {MACHINE SETUP->
MODEL->4047R} X
33538 AUXILIARY LIFT DOWN VALVE -
OPEN CIRCUIT
None 3_3 • Disable Highside Output
• Open Lowside Output
• LiftDownState = PREVENTED
• LiftUpState = PREVENTED Open Circuit detected on LIFT_DN_VLV_2 AND
{MACHINE SETUP-> MODEL->4047R} X
33539 AUXILIARY LIFT DOWN VALVE -
SHORT TO BATTERY
None 3_3 • Disable Highside Output
• Open Lowside Output
• LiftDownState = PREVENTED
• LiftUpState = PREVENTED Short to Battery was detected on
LIFT_DN_VLV_2 AND {MACHINE SETUP->
MODEL->4047R} X
33562 BEACON LIGHT – SHORT TO
BATTERY
None 3_3 • Disable output
• No motion restrictions Short to Battery was detected on BEACON AND
{MACHINE SETUP-> BEACON=YES}.
• This will only be triggered when ARMGUARD
is active and the short to battery occurs under
the Arm guard limit.
X
336 LIFT DOWN VALVE – OPEN CIR-
CUIT None 3_3 • Disable Highside Output
• Open Lowside Output
• LiftDownState = PREVENTED
• LiftUpState = PREVENTED Open Circuit detected on LIFT_DN_VLV X
3361 BRAKE - SHORT TO GROUND None 3_3 • BrakeReleaseState = FALSE
(Brake Release Option is not
allowed to disengage brakes)
• Disable output Short to Ground was detected on the
GM_V5-5_Tow_Out digital output. This DTC
shall only be reported if the BrakeReleaseState
was set to TRUE X
33674 PLATFORM POWER – SHORT TO
BATTERY
None 3_3 GroundMode
• Disable output Short to Battery was detected on
PLATFORM_PWR
Ignore this Fault in PlatformMode X
33675 PLATFORM POWER – OPEN
CIRCUIT
None 3_3 • N/A Ignore this fault for following reasons.
• N/A in Ground Mode
• No diagnostic value in Platform Mode, would
only increase startup time.
