P1885 – OBD-II DTC

OBD-II DTC P1885 – Transmission Transfer Case Disengaged Solenoid Short to Battery

DTC P1885 meaning

DTC P1885 refers to a diagnostic trouble code indicating a problem with the Transmission Transfer Case Disengaged Solenoid. Specifically, it signifies that there is a short circuit to the battery in the solenoid circuit. This solenoid is responsible for engaging and disengaging the transfer case, which is crucial for vehicles with four-wheel drive (4WD) or all-wheel drive (AWD) systems.

DTC P1885 symptoms

Common symptoms associated with DTC P1885 may include:

• Inability to engage or disengage the transfer case
• Warning lights on the dashboard, such as the check engine light
• Unusual noises from the transfer case
• Slipping or erratic shifting of the transmission
• Reduced traction or control in 4WD or AWD mode

DTC P1885 causes

Several factors can lead to the occurrence of DTC P1885, including:

• Faulty transmission transfer case disengaged solenoid
• Wiring issues, such as frayed or damaged wires
• Corrosion or poor connections in the electrical circuit
• Faulty powertrain control module (PCM)
• Issues with the transfer case itself

DTC P1885 seriousness

DTC P1885 is considered a serious issue, particularly for vehicles that rely on 4WD or AWD systems. If left unaddressed, it can lead to:

• Inability to drive in adverse conditions, such as snow or mud
• Increased wear and tear on the transmission
• Potential for further damage to the transfer case
• Safety risks due to loss of vehicle control

How to diagnose DTC P1885

To diagnose DTC P1885, follow these steps:

1. Use an OBD-II scanner to confirm the presence of the P1885 code.
2. Inspect the wiring and connectors related to the transfer case disengaged solenoid for damage or corrosion.
3. Test the solenoid for proper operation using a multimeter.
4. Check the power supply to the solenoid to ensure it is receiving the correct voltage.
5. Examine the transfer case for any mechanical issues that may affect solenoid operation.
6. Clear the code and perform a road test to see if the code reappears.

How to fix DTC P1885 step-by-step instructions

To fix DTC P1885, follow these steps:

1. Disconnect the battery to ensure safety while working on the electrical system.
2. Inspect and repair any damaged wiring or connectors related to the transfer case disengaged solenoid.
3. If the solenoid is faulty, replace it with a new one.
4. Reconnect the battery and clear the DTC using an OBD-II scanner.
5. Perform a road test to verify that the issue has been resolved and the code does not return.

How to erase DTC P1885

To erase DTC P1885, follow these steps:

1. Connect an OBD-II scanner to the vehicle’s diagnostic port.
2. Turn on the ignition without starting the engine.
3. Navigate to the “Erase Codes” or “Clear Codes” option on the scanner.
4. Confirm the action to clear the trouble codes.
5. Disconnect the scanner and start the vehicle to ensure the code does not reappear.
