B210D on Jeep
Manufacturer-Specific Body Code (low battery voltage / starter or relay condition)
B210D on Jeep vehicles indicates manufacturer-specific body code (low battery voltage / starter or relay condition). Au7o has documented this code across 1 Jeep model — most commonly on Grand Wagoneer. B210D is a manufacturer-specific body code whose meaning varies by automaker. On Dodge/Chrysler it is commonly reported as a low battery-voltage condition seen by a body module, while some other references list a starter or relay state. It generally indicates a power-supply or control-circuit issue detected by a body-domain module rather than a mechanical engine fault. Confirm the exact definition with make-specific service data before repair. Typical repair costs on Jeep range from $200 to $1,800, depending on the specific model and root cause.
Common Causes of B210D
- •Low or weak battery / undercharged system
- •Failing alternator or charging-system fault
- •Corroded or loose battery terminals and grounds
- •Voltage drop in body-module power feeds
- •Stuck or faulty relay (on makes using that definition)
- •Faulty body control module
B210D on Jeep by Model
Jeep Grand Wagoneer(1 issue)
- Battery drain / no-start due to telematics or module staying awake (parasitic draw)2022-2024
Owner reports and NHTSA complaints describe repeated dead 12V batteries and no-start conditions on Grand Wagoneer, often after sitting overnight or a few days. The pattern is consistent with parasitic draw from modules not going to sleep (commonly telematics/infotainment-related controllers), leading to low voltage and cascading network faults.
