Description:

This error code is generated when the control software detects an activated declutch switch on the range shift lever during the starting procedure while the range shift lever is not in the park position. Possible reasons include operator error, a defective declutch switch, or a signal voltage short-circuited to the system voltage.

Reaction:

The function of the declutch switch on the range shift lever is turned off by the control software. The function must be reactivated in address PTQ167.

Recommendations:

Verify Operator Procedure:

• Ensure the operator is not actuating the declutch switch during start-up. Provide proper training if necessary.

Inspect Declutch Switch:

• Check the declutch switch on the range shift lever for signs of damage or defect. Replace the switch if necessary.

Test Voltage Levels:

• Use a multimeter to measure the signal voltage in the circuit of the declutch switch. Ensure it remains within the specified range.

Check for Shorts:

• Inspect for any short circuits to the system voltage along the wiring of the declutch switch. Repair any identified shorts.

Update Control Software:

• Ensure that the control software is updated to the latest version. Firmware updates might improve handling of the declutch switch signals.

Consult Manufacturer Support:

• If the issue persists, consult technical support or the manufacturer for further diagnostics and assistance.

Reactivation of Function:

• After resolving the issue, reactivate the declutch switch function in address PTQ167.

Monitor System Performance:
