PTP 000168.04 – PTP Unswitched Supply Voltage Low

PTP 000168.04 (PTP 168.04)

Code: 000168.04

Shortcode: 168.04

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.
