Yale MPB045VGN24T2646:
Fault code 30227

Does anyone have any experience with error/fault code 30227 on an electric pallet jack. We cannot find any information covering what the code represents.

Thanks

CAUSE A - ENCODER WIRING FAULT
PROCEDURE OR ACTION:
NOTE: Perform Step 1 with key in ON position.
1.

Disconnect the traction motor encoder connector CPS03 and measure voltage between socket 1 and B(-).
Is voltage 5 ± 0.5 Vdc?
YES: Proceed to Step 2.
NO: Inspect circuit 250 for open or short.
2.

Measure resistance between the encoder connector CPS03, socket 4 and B(-).
Is resistance <1 ohm?
YES: Disconnect battery and proceed to Step 3.
NO: Inspect ground circuit 102 for open or short.
3.

Disconnect traction controller connector CPS01 and measure resistance between socket 32 and the encoder connector CPS03, socket 3.
Is resistance <1 ohm?
YES: Proceed to Step 4.
NO: Inspect signal circuit 578 for open or source of excessive resistance.
4.

Measure resistance between socket 31 of the traction controller connector CPS01 and socket 2 of the encoder connector CPS03.
Is resistance <1 ohm?
YES: Proceed to CAUSE C.
NO: Inspect signal circuit 577 for open or source of excessive resistance.
CAUSE B - FAULTY TRACTION ENCODER
PROCEDURE OR ACTION:
1.

Measure voltage between sockets 31/32 and B(-) of the traction connector CPS01; operate traction motor.
Was voltage present?
YES: Proceed to CAUSE D.
NO: Replace encoder. Make sure to indicate the DTC code(s) on the warranty claim to include an accurate problem description leading to controller replacement.
CAUSE C - FAULTY TRACTION MOTOR
PROCEDURE OR ACTION:
NOTE: Disconnect battery.
1.

Measure continuity between the motor terminals U and V.
Is continuity present?
YES: Proceed to Step 2.
NO: Repair or replace faulty motor.
2.

Measure continuity between the motor terminals U and W.
Is continuity present?
YES: Proceed to Step 3.
NO: Repair or replace faulty motor.
3.

Measure continuity between the motor terminals W and V.
Is continuity present?
YES: Proceed to CAUSE D.
NO: Repair or replace faulty motor.
CAUSE D - FAULTY TRACTION CONTROLLER
PROCEDURE OR ACTION:
1.

If no faults are found, replace controller. Make sure to indicate the DTC code(s) on the warranty claim to include an accurate problem description leading to controller replacement.

D.

FAULTY TRACTION CONTROLLER
NOTE
Please refer to the end of this procedure for supporting diagrams.
COMPONENT OPERATIONAL CHECK
PROCEDURE OR ACTION:
1.

Remove cover from truck frame. Inspect transmission and tire for obstructions or binding.
Is object impeding steering motor?
YES: Remove object; clear code and verify repair.
NO: Proceed to Step 2.
NOTE: Use caution when performing the following test. The traction controller and brake will be OFF.
2.

With key in OFF position, locate the brake override connectors on left and right side of traction motor. Disconnect CRP04-B and CRP04-A, connect CRP04-B to the electromagnetic brake connector. Move the truck back and forward and move handle side to side.
Does truck move and rotate freely?
YES: Connect CRP04-B AND CRP04-A and proceed to Step 3.
NO: Inspect transmission.
3.

Conduct a visual inspection of all connectors/wiring associated with the fault code.
Are any faults detected/observed?
YES: Repair/replace connector or wiring associated with faults found. Refer to the appropriate Electrical SystemYRM.
NO: Proceed to Step 4.
4.

Re-key the vehicle.
Is the code still present?
YES: Proceed to CAUSE A.
NO: Problem may be intermittent.
