Description:

This error code is triggered when the supply voltage to the PTP control unit drops below 10.5 V for longer than 2.0 seconds. Low supply voltage can impact the proper functioning of the control unit.

Reaction:

The control unit commands the transmission to neutral to prevent potential operational issues.

Recommendations:

• Inspect Electrical Connections:
  Check all electrical connections to the PTP control unit for loose or corroded contacts. Secure and clean as necessary.
• Battery Check:
  Ensure that the battery is fully charged and in good condition. Replace the battery if it is weak or failing.
• Alternator Output:
  Verify that the alternator is providing adequate charging voltage to the system. Repair or replace the alternator if it is not functioning correctly.
• Wiring Inspection:
  Inspect the wiring harness for any damage or wear that could cause voltage drops. Repair or replace damaged wiring.

Note:

Maintaining stable supply voltage to the PTP control unit is vital for consistent and reliable operation. Regular checks of the electrical system can help prevent low voltage issues.
