Troubleshooting Table 20: Hydrostatic Travel Drive System Troubleshooting ProblemPossible CauseCorrective Action

Allow longer warm-up

Drive system noisy

Hydraulic oil viscosity too heavy

Low hydraulic oil level

Air in hydraulic system

Drive motor(s) or hydrostatic pump(s) internal damage/leakage

Low hydraulic oil level

Replace hydraulic oil with proper type/ grade. See “Fluids/Lubricants Types and Capacities” on page33

Top-off hydraulic oil. See “Checking Hydraulic Oil Level” on page133

Cycle lift and tilt cylinders to maximum stroke and maintain for a few seconds to clear air from the hydraulic system

Contact dealer

Top-off hydraulic oil. See “Checking Hydraulic Oil Level” on page133

Low hydraulic system charge pressureContact dealer

Drive motor(s) or hydrostatic pump(s) internal damage/leakage

Contact dealer

Sluggish acceleration

Engine running rough

Poor fuel quality or incorrect fuel type/ grade. Replace fuel with proper type/ grade. See “Fluids/Lubricants Types and Capacities” on page33

Restricted fuel filter/fuel system. Replace fuel filter; remove restriction. See “Changing Fuel Filter” on page132

Contact dealer

Drive sensitivity set too low

See “Control Sensitivity Configuration Screen” on page50

Travel drive does not track straight when left joystick is in the forward or reverse position

Drive system needs to be adjusted for straight tracking

See “Straight Tracking Adjust” on page57

Electrical Troubleshooting

ProblemPossible CauseCorrective Action

Battery terminals or cables loose or corroded

Battery malfunction

Loss of electrical power

Blown main fuse

Blown main fuse

Instrument display does not activate when ignition is on

Battery terminals or cables loose or corroded

Clean battery terminals/cable connections and tighten

Test battery. Recharge/replace as necessary

Correct over-current problem and replace main fuse. See “Fuses and Relays” on page146

Correct over-current problem and replace main fuse. See “Fuses and Relays” on page146

Clean battery terminals/cable connections and tighten

Ignition switch malfunctionReplace switch

In very cold weather, display screen slow to display

Loose/corroded starter electrical connections

Battery terminals or cables loose or corroded

Starter does not engage when key switch turned to start position

Work/road lights malfunction

Wait a few minutes for display to activate

Check/tighten/clean connections

Clean battery terminals/cable connections and tighten

Starter relay malfunctionContact dealer

Battery malfunction

Test battery. Recharge/replace as necessary

Starter solenoid malfunctionContact dealer

Starter or pinion malfunctioningRepair/replace as needed

Error code “0”. Arm rest/safety bar in raised position; cab door not closed (if equipped)’ operator’s seat not occupied

Single light not working; light bulb burned out, faulty wiring

No lights; blown fuse

Lower arm rests/safety bars to operating position. Engine will not start with either arm rest/safety bar raised, or the cab door open (if equipped). Occupy operator’s seat

Check and replace light bulb as needed, check wiring connections

Correct over-current problem and replace fuse. See “Fuses and Relays” on page146

Light switch malfunctionReplace light switch

Poor electrical groundCheck ground wire connections

Non-functional cab heater

Error Codes

Thermostat oriented in housing with support bales/arms blocking feed hole to heater hose. (SOME heat delivered through heater)

Replace thermostat; align bales/arms properly (parallel to engine crankshaft) in housing.

The tables in this section describe error codes which may be reported on the multi-function display screen. More than one error can be reported at one time and each error code will display on a separate screen. Multiple errors will be reported on a summary screen. See “Multi-Function Display” on page46.

NOTE: Error codes remain displayed after the error is co rrected. Press the display several times to rotate through all display screens to refresh the display; corrected error codes will not reappear in the screen rotation.

Controller Communication Error Codes

NOTE: See “Control Modules” on page152 for controller locations.
