In this article, we’ll provide step-by-step instructions and useful tips to help you fix the problem and get your wipers working properly again.
What is the B1435 Error Code?
The B1435 error code is a diagnostic trouble code (DTC) that indicates a problem with the wiper hi/low speed relay coil circuit. This circuit is responsible for controlling the speed of your wipers, and if it’s not functioning properly, you may experience issues such as wipers that don’t work at all, or wipers that only work at one speed.
Diagnosing the Problem
To diagnose the problem, you’ll need a few tools, including a multimeter and a wiring diagram for your vehicle. Here are the steps to follow:
Step 1: Check the Fuse
The first thing to check is the fuse for the wiper hi/low speed relay coil circuit. Use your vehicle’s manual to locate the fuse box and find the fuse for the wipers. Use a multimeter to test the fuse for continuity. If the fuse is blown, replace it and test the wipers again.
Step 2: Check the Relay
If the fuse is not the problem, the next step is to check the wiper hi/low speed relay. Use your wiring diagram to locate the relay and remove it from its socket. Use a multimeter to test the relay for continuity. If the relay is faulty, replace it and test the wipers again.
Step 3: Check the Wiring
If the fuse and relay are not the problem, the issue may be with the wiring. Use your wiring diagram to locate the wires for the wiper hi/low speed relay coil circuit. Use a multimeter to test the wires for continuity. If there is a break in the wiring, you’ll need to repair or replace the affected wires.
