B1101 CHEVROLET Code - Battery Voltage Too High
|B1101 CHEVROLET code possible causes
- Faulty Sensing and Diagnostic Module(SDM)
- Sensing and Diagnostic Module(SDM) harness is open or shorted
- Sensing and Diagnostic Module(SDM) circuit poor electrical connection
|How is the B1101 CHEVROLET code repair?Start by checking the "Possible Causes" listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector's pins.
|What is the cost to diagnose the B1101 CHEVROLET code
Labor: 1.0The cost to diagnose the B1101 CHEVROLET code is 1.0 hour of labor. The auto repair's diagnosis time and labor rates vary by location, vehicle's make and model, and even your engine type. Most auto repair shops charge between $75 and $150 per hour.
|What are B1101 CHEVROLET code possible symptoms?
- Air Bag Warning Light ON
|What is B1101 CHEVROLET code meaning?When the ignition switch is turned to ON, the Sensing and Diagnostic Module(SDM) will perform turn-on test to diagnose critical malfunctions within SDM itself.
Upon passing these test ignition and deployment loop voltages are measured to ensure that they are within their normal voltage ranges. The SDM monitors the voltages at the driver low and the passenger low to detect shorts to ground or voltage in the deploy loops.
The SDM checks the wiring connection to each inflator by letting the infinitesimal current flow through the internal circuit and verify the resistance. But if the voltage is out of range, SDM is unable to check the airbag system properly.

Precautions for SRS “AIR BAG” and “SEAT BELT PRE-TENSIONER” Service
- Never probe the electrical connectors on air bag, side air curtain modules or seat belts.
- Never disassemble or tamper with safety belt buckle/retractor pretensioners, adaptive load limiting retractors, safety belt inflators, or probe the electrical connectors.
- Do not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.
- Before servicing the SRS, turn ignition switch OFF, disconnect both battery cables and wait at least 3 minutes. For approximately 3 minutes after the cables are removed, it is still possible for the air bag and seat belt pre-tensioner to deploy. Therefore, do not work on any SRS connectors or wires until at least 3 minutes have passed.
