Messages and Caution Codes

Code Title Lower Solenoid Coil (Sol 1) Driver Shorted or Open

Operator DisplayC61

TA Flash Code “3,5”

System ResponseLower function not available. Lift functions normally.

Reason Lower coil driver open or shorted.

Tests to Run Examine for short or open for lower coil, or related wiring. Resistance of coil should be approximately 39 Ohms. See “Pinout Matrix” on page8-9.

How to Clear Investigate cause of open or short and repair or replace as needed.

Code C62

Code Title Horn Coil Driver Shorted or Open

Operator DisplayC62

TA Flash Code “3,4”

System ResponseHorn function not available.

Reason Horn coil driver open or shorted.

Tests to Run Examine horn and related wiring. See “Pinout Matrix” on page8-9

How to Clear Investigate cause of open or short and repair or replace as needed.

Code C64

Code Title Digital Output Overcurrent

Operator DisplayC64

TA Flash Code “2,6 or 2,7”

System ResponseTravel Alarm Inoperable. Travel limited to coast speed.

Reason Digital output driver overcurrent

Tests to Run Examine for shorted travel alarm, or related wiring. See “Service Input/Output Display” on page3-20. See also “Pinout Matrix” on page8-9

How to Clear Investigate cause of short and repair or replace as needed.

Code C66

Code Title Brake Coil Driver Open or Shorted

Operator DisplayC66

TA Flash Code “3,2”

System ResponseNo Travel

Model 6210 Maintenance Manual

Reason The TA detected an open or short in the Brake Coil Driver 2 circuit.

Tests to Run Troubleshoot wiring to and from the brake and the brake coil for opens or shorts. The brake coil should have approximately 14 ohms resistance. See “Pinout Matrix” on page8-9

How to Clear Determine cause of short or open circuit and correct.

Code C67

Code Title EM Brake Not Set

Operator DisplayC67

TA Flash Code “9,2”

System ResponseNo Travel

Reason Triggered if the brake switch is open (handle up) and the brake is applied and no motion is detected and then motion is detected without releasing the brake. A weak brake or excessive skidding and then gripping during a deadman braking event could cause this.

Tests to Run

Troubleshoot wiring to and from the brake and the brake coil for opens or shorts. The brake coil should have approximately 14 ohms resistance. See “Pinout Matrix” on page8-9 . Check brake gap. See “Air Gap Inspection” on page7-31

How to Clear Return throttle to neutral. Replace the brake or rotor as needed.

Code C68

Code Title Brake SelfTest Failed

Operator DisplayC68

System ResponseTraction performance limited to 1 MPH (1.6 km/h)

Reason Brake did not hold the truck stationary during SelfTest.

Tests to Run Check for worn brake. Check brake gap. See “Air Gap Inspection” on page7-31 . Verify brake release bolts are not installed.

How to Clear Replace the brake or rotor as needed. Cycle the truck OFF/ON.

Code C70

Code Title Motor Temperature Sensor Fault

Operator DisplayC70

TA Flash Code “2,9”

System ResponseTraction performance reduced.

Section 6.Messages and Codes

Messages and Caution Codes

Reason Failure of motor temperature sensor. Sensor or wiring to traction motor open or shorted. Resistance of temperature sensor should be from 990 to 1100 Ohms at room temperature.

Tests to Run

Examine component and related wiring for shorts or open condition. See “Service Input/Output Display” on page3-20. See also “Pinout Matrix” on page8-9.

How to Clear Determine cause of short or open circuit and correct.

Code C71 Code C72

Code Title Sensor Bearing Defective (Speed Sensor)

Operator DisplayC71

TA Flash Code “3,6”

System ResponseTraction performance limited.

Reason TA detects the loss of traction motor encoder input (missing phase(s), power, and so forth).

Tests to Run

Use service key and test the traction motor encoder by scrolling to the RPM display (D) in diagnostic displays and command the motor to rotate. The value displayed is the motor RPM as reported from the TA. Examine wiring to traction motor encoder. See “Service Input/Output Display” on page3-20. See also “Pinout Matrix” on page8-9.

How to Clear Troubleshoot and repair wiring to Traction Motor Encoder. If still not clear, replace the encoder.

Code Title Traction Motor Stalled

Operator DisplayC72

TA Flash Code “7,3”

System ResponseTraction performance limited until code cleared. Brake is activated on motor stall.

Reason TA detects that the traction motor has stalled for 5 seconds.

Tests to Run

Use service key and test the traction motor encoder by scrolling to the RPM display (D) in diagnostic displays and command the motor to rotate. The value displayed is the motor RPM as reported from the TA. See “Service Input/Output Display” on page3-20. See also “Pinout Matrix” on page8-9

How to Clear Cycle the truck OFF/ON.

Code 075

There is no Code 075, this is a misinterpretation of the SLO code. Refer to Code ‘SLO’ for causes and how to clear.

Code C95

Code Title Lift-Limit with Bypass Fault

Operator DisplayC97

Model 6210 Maintenance Manual

System ResponseLift is disabled if the forks are above the lift-limit switch.

Reason Bypass button is closed at key-on or the button is held closed for more than 10 seconds during run time.

Possible CausesNone

How to Clear Release the bypass button.

Code C96

Code Title Pendant Voltage Out of Neutral

Operator DisplayC96

System ResponsePendant lift/lower disabled, handle lift/lower and travel allowed.

Reason Output voltage from the pendant is out of neutral at key-on, or the presence signal is sensed at key-on. During runtime, the presence signal is sensed for more than 10 seconds without an accompanying lift/lower request. During runtime, the lift/lower pendant signal is sensed for more than 10 seconds without an accompanying presence signal.

Possible Causes1.On the pendant, a lift or lower button and/or the enable switch failed or was pressed at startup.

2.Shorted or open pendant wiring or failed pendant. Check pendant wiring for correct voltages.

How to Clear Code clears when the problem is resolved and the truck is turned OFF and ON.
