How to Diagnose and Solve B1616 Wiper Rear Disable Switch Circuit Open Issues

Introduction

If you’re experiencing issues with your wiper rear disable switch circuit, you may have encountered the B1616 error code. This code indicates that there is an open circuit in the wiper rear disable switch circuit, which can cause your wipers to malfunction. In this article, we’ll guide you through the process of diagnosing and solving this issue.

Step 1: Check the Wiper Rear Disable Switch

The first step in diagnosing the B1616 error code is to check the wiper rear disable switch. This switch is located on the dashboard of your car and is responsible for controlling the rear wiper. To check the switch, turn on your car and activate the rear wiper. If the wiper doesn’t work, the switch may be faulty.

Step 2: Check the Wiring

If the wiper rear disable switch is working correctly, the next step is to check the wiring. Start by inspecting the wiring for any visible damage or wear. If you notice any damage, you’ll need to replace the wiring. If the wiring looks fine, use a multimeter to check for continuity in the circuit. If there is no continuity, there may be an open circuit in the wiring.

Step 3: Check the Wiper Motor

If the wiring is fine, the next step is to check the wiper motor. Start by disconnecting the wiring harness from the motor and using a multimeter to check for continuity in the circuit. If there is no continuity, the motor may be faulty and will need to be replaced.

Step 4: Check the Wiper Relay

If the wiper motor is working correctly, the next step is to check the wiper relay. The relay is responsible for controlling the power to the wiper motor. Start by locating the relay and checking for any visible damage or wear. If the relay looks fine, use a multimeter to check for continuity in the circuit. If there is no continuity, the relay may be faulty and will need to be replaced.

Step 5: Check the Fuse

If all of the above steps have been completed and the issue still persists, the final step is to check the fuse. The fuse is responsible for protecting the circuit from power surges and shorts. Start by locating the fuse and checking for any visible damage or wear. If the fuse looks fine, use a multimeter to check for continuity in the circuit. If there is no continuity, the fuse may be faulty and will need to be replaced.

Conclusion

Diagnosing and solving the B1616 error code can be a daunting task, but by following these steps, you can easily identify and fix the issue. Remember to always check the wiper rear disable switch, wiring, wiper motor, relay, and fuse in that order. By doing so, you can ensure that your wipers are functioning correctly and safely.
