Is airbag code B1134 and ABS code C1106 related?

No, the two systems are completely separate from each other and each have their own computer. Be careful with the airbag system if you're not familiar with it! An accidental deployment can cause serious injuries or, God forbid, even kill you! Hope that helps! Jim

Thank you Jim. Are you able to give me a little bit more insight to the B1134 code? I know that it's for the left side airbag module, and the connections all look ok under the seat.

See if there's a recall on your air bags , A gubmint/DMV site would probably be best .

I did check on that, no open recalls.

I have inspected the wiring, connectors, and module for the B1134 code. Is it possible that if the module was replaced and the control unit was not reset that the light will still flash?? I have also tried resetting the light via a scanner and the reset procedure I found online. The light will come back on and continue to flash? My C1106 code is due to the left rear speed sensor, I have ordered a new one and will be replacing it soon. I will update after the repair is confirmed.

Both the airbag system and the ABS system reset each time the ignition is turned off. The computers clear themselves and when you start the engine again, or put the key in the run position, both systems go through a self check. If you're absolutely sure the wiring going to the left hand (driver's side) side impact module is good then the module will need to be replaced. DO NOT test the module or the wiring with a self powered test light or multi meter!! This WILL CAUSE the module to deploy!! If you are replacing the module, remove the SRS fuse and wait at least 5 minutes for the system to discharge!! The system retains a charge for a few minutes after battery power is lost so that in the event the battery becomes disconnected in a collision the airbags will still deploy! Make sure to wear rubber gloves to prevent a static discharge from your body when you handle the airbag module!! Again, this can cause the module to deploy! Once you have removed the module from the vehicle carry it with the front of the module facing away from your body! The module is now considered unstable! Place the module on a firm surface like the sidewalk or a piece of plywood at least 6 feet away from the vehicle face UP. Follow the same procedure when installing the new module. The old module MUST be safely and remotely deployed before disposing of it in the trash. Get two pieces of wire AT LEAST six feet long and attach them to the connector on the old module that is still facing UP on the firm surface. Touch the wires to the positive and negative sides of an automotive battery to safety deploy the old airbag. Remain AT LEAST 6 feet away from the module until it's been safely deployed. Wait a few minutes for the module to cool then you can throw it in the trash! Please follow these instructions, people have been killed by airbags that are improperly handled and improperly deployed!! Hope that helps! Jim

Thank you Jim, I will look into the wiring again. Just as a double check. Concerning the C1106 code for the ABS light, I have replaced the speed sensor and the ABS is still on. Is there a drive cycle that I need to follow, I have a scanner hooked up to the vehicle and while driving, I have the live data on, the LR speed sensor isn't registering MPH. Not sure where to go from here? Any suggestions?

On the C1106 code the ABS computer is not receiving a pulse signal from the sensor. This could be caused by a dirty sensor or ABS rotor (brake dust), excessive gap between the sensor and the ABS rotor, bad connection at the sensor, a problem with the wiring, or a bad ABS computer. Nissan issued a technical service bulletin (TSB) on this. To help diagnose it ask your local Nissan Dealer for a copy of the TSB. The ABS computer is the last suspect in this list of possible causes since you are getting a code. Always remember, the computer will never tell on itself. But it will tell on everybody else! In other words, if the ABS light was on but you had no codes, the ABS computer would be my first suspect. Just to be clear, the left rear of the vehicle is the driver's side rear. Not trying to be condescending, but you'd be surprised how many people don't know that when talking about a side of the vehicle, that it's the side of the vehicle from when you're sitting in the driver's seat. Hope that helps! Jim
