Code B1981 RAM Description
The B1981 code indicates a malfunction in the Power Liftgate Latch Control 1 Circuit, specifically signaling a high voltage condition. This code is typically associated with vehicles equipped with a power liftgate feature, which allows for automatic opening and closing of the rear hatch. The latch control circuit is responsible for communicating the position and operational status of the liftgate latch to the vehicle’s body control module (BCM).
Common Causes of B1981 RAM
- Faulty power liftgate latch assembly or motor.
- Damaged or frayed wiring in the latch control circuit.
- Corroded or loose electrical connectors affecting circuit integrity.
- Malfunctioning body control module (BCM) that misreads the latch status.
- Environmental factors, such as moisture or debris, causing short circuits.
Symptoms of B1981 RAM
- The power liftgate does not respond to the remote or interior switch commands.
- The liftgate opens or closes erratically or partially.
- Warning lights or messages appear on the dashboard indicating a liftgate issue.
- Unusual noises or grinding sounds when attempting to operate the liftgate.
- The liftgate remains in the open or closed position and cannot be manually operated.
How to Fix B1981 RAM
- Diagnostic Testing: Begin by using an OBD-II scanner to confirm the B1981 code and check for any additional codes that may provide further insight into the issue.
- Visual Inspection: Inspect the wiring harness and connectors associated with the power liftgate latch for signs of damage, corrosion, or loose connections.
- Component Testing: Test the power liftgate latch assembly and motor for proper operation using a multimeter to check for voltage and continuity.
- Repair or Replace: Depending on the findings, repair any damaged wiring or connectors, or replace the faulty latch assembly or motor as necessary.
- Clear Codes and Test: After repairs, clear the diagnostic trouble codes and perform a functional test of the liftgate to ensure that it operates correctly and that the B1981 code does not return.
Cost to Fix B1981 RAM
** The cost to diagnose and repair the B1981 code can vary significantly based on the specific vehicle make and model, as well as the location of the repair shop. On average, the total cost for parts and labor may range from $150 to $600.
