Description:

This diagnostic trouble code indicates that the declutch switch on the range-shift lever is actuated even though it is deactivated in address PTQ 167 but activated in address TIQ 168. This discrepancy prevents the clutch function from being carried out.

Reaction:

When this fault is detected, the control software disables the function of the declutch switch on the range-shift lever.

Recommendations:

• Verify Software Settings:
  • Check the settings for addresses PTQ 167 and TIQ 168 to ensure they are configured correctly.
  • Adjust the settings to ensure consistency between the two addresses.
• Inspect Declutch Switch:
  • Check the declutch switch for proper operation and any signs of malfunction.
  • Replace the switch if it is found to be faulty.
• Update Software:
  • Ensure the control software is up-to-date, especially if using older software versions.
  • Install any available updates or patches to address the issue.
• Consult Technical Support:
  • If the issue persists, contact technical support or the manufacturer for further assistance.

Note:

Consistent and correct configuration of software addresses is essential for the proper operation of the declutch switch. Regular updates and inspections can help prevent discrepancies and ensure reliable performance.
