In this segment, I'll show how to read B1006 & other Harley DTC (Diagnostic Trouble Codes) step by step. Step 1: Hold down the odometer button for 5 seconds. Don't forget to turn your ignition switch on while pressing the odometer button. Step 2: Release the odometer button & you should see "DIAG" on display. This DIAG refers to Diagnostic. Step 3: Now tap on the odometer one time. You'll see "ECM" on the screen. You'll see either "ECM Y" or "ECM N." The letter Y will come if any error codes are available. Otherwise, you'll see the letter N. Step 4: If there's any code available in ECM, long-press the odometer button again & you'll see the codes. The B1006 code belongs to the ECM (Engine Control Module) section & you should see it then. Step 5: To see other codes of BCM, SPDO, ABS, RAD & more – press the odometer button & follow from step 1 in a cyclic manner. At one point, you should see ECM again. How To Solve B1006 Error Code On Harley? Solving the B1006 error code can be tricky as it occurs for various reasons. Don't worry; I won't disappoint you by saying – the exact solution depends on the bike condition. Here are some well-known troubleshooting methods that can eventually solve your problem. Clearing The Code: The Easy Method The obvious & easiest way of solving the B1006 code is via clearing the code. It's normal for Harley Davidson Motorcycles to show random codes after the repairing session & they're easily cleanable. To clear the B1006 code, you've to view/read the code first, following the step-by-step guide I mentioned above. Later on, press & hold the odometer button until you see "CLEAR" on display. Now gently press the odometer button & the code will be cleared. Try going on a ride for 10 to 15minutes. If the code doesn't reappear – congrats! You've solved the problem. Otherwise, try following the next methods. Check & Replace The Battery Ground Cable The B1006 code can appear for battery ground cable as well. Don't underestimate the ground cable, as it controls a lot of things on your bike. Ground cable doesn't mean a cable that touches the ground. Instead, your bike's body is considered as ground & the cable that links the battery with the body is called battery ground cable. To check battery ground cable, follow the next step by step tutorial: Step 1: Detach the ground cable from the battery & body Step 2: Collect an Ohmmeter & measure the electrical resistance of both sides of the cable. Step 3: Now play with your cable. I mean, try bending it as much as you can & check if there's any cracking or breaking sound. Step 4: Lastly, measure the electrical resistance of both sides of the cable for the second time. If you see a slight increase in reading, replace the cable. Lots of users found success replacing their faulty ground cable & you should give it a try as well. Check & Replace The Regulator The regulator plays a big role in increasing the accessory line voltage that causes the B1006 code. However, it's not an obvious reason for getting the B1006 code. Rather it's just a potential reason. To check your regulator, you'll need a Voltmeter first. Now connect your Voltmeter with the battery & start the motor. While the motor is running, you should see a reading of 13.2 to 13.8V. If you see anything more than 13.8 Volt, then the regulator probably has a problem. Try replacing the regulator with a new one & the error code should go away permanently. Check & Replace The Load Equalizer Whether you're using a load equalizer from Badlands or Custom Dynamics, there are always chances of getting a faulty one (unfortunately). To check if your load equalizer is bad or not, try replacing the load equalizer with your stock Turn Signals. If the code goes away & never returns, it's probably the equalizer that was bringing the B1006 code. Replace your load equalizer & you're all set. Common Mistakes While Solving The B1006 Code You may try to solve the B1006 code by yourself to avoid the high hourly rates of automotive stores. However, you've to be very conscious while operating your work. Here are some of the common mistakes that you may encounter while solving the code: Failing to read the actual resistance value of battery ground cableMessing up everything while trying to work without a manualSoldering mistakes due to lack of experience. How Serious Is Code B1006 On Harley? Code B1006 refers to the overvoltage on any accessories part of Harley. It's a bad thing for the accessories & the whole bike.
