Description:

This diagnostic trouble code is generated when the control software expects but does not receive wheel speed signals from both channel 1 and channel 2. This indicates a problem in the circuit of the lead for the wheel speed signal between the control unit for range shifting and the control unit for gear shifting.

Reaction:

When this error is detected, the control software may limit or disable the transmission functions.

Recommendations:

Inspect Wheel Speed Sensors:

• Check both wheel speed sensors for any signs of damage or disconnection.
• Ensure that the sensors are properly aligned and mounted.

Check Wiring and Connections:

• Inspect the wiring and connections to the wheel speed sensors for signs of damage, wear, or corrosion.
• Repair or replace any damaged wires or connectors.

Verify Control Units:

• Ensure that both the control unit for range shifting and the control unit for gear shifting are functioning correctly and processing the wheel speed signals properly.
• Reprogram or update the control unit software if necessary.

Consult Technical Support:

• If the issue persists, seek assistance from technical support or a qualified technician for further diagnosis and repair.

Monitor System:

• After repairs, monitor the wheel speed sensors to ensure they are providing accurate and consistent readings.

Note:

Regular inspection and maintenance of the wheel speed sensors and their connections can help prevent speed signal issues and ensure reliable operation of the transmission system.
