Description:

This diagnostic trouble code, TSC 003509.04, is triggered when the voltage measured at the positive lead of the power supply to the 5-volt components (TLS position sensor B53 and TLS oil pressure sensor B167) is below 4.65 volts. This indicates a short to ground in the circuit.

Reaction:

When this error occurs, the affected sensors may not receive adequate power, leading to incorrect readings and impaired functionality of the TLS system.

Recommendations:

Inspect Power Supply Circuit:

• Check for Shorts to Ground:
  • Examine the wiring for any signs of short circuits to ground.
  • Repair any identified shorts in the circuit.

Inspect Sensors:

• Check Sensor Connections:
  • Ensure that the TLS position sensor B53 and TLS oil pressure sensor B167 are properly connected and not damaged.
  • Replace any faulty sensors.

Verify TSC Internal Circuitry:

• Check for Internal Faults:
  • Inspect the internal circuitry of the TSC for any interruptions or faults.
  • Repair or replace the TSC if necessary.

Note:

Maintaining the stability of the 5-volt power supply to the TLS sensors is crucial for accurate sensor readings and proper system functionality. Regular inspections and maintenance of the power supply circuit and sensors are recommended.
