B1C62 — Battery Saver Relay Output Circuit

System: Body  |  Type: Manufacturer-Specific  |  Make: Land Rover

About B1C62

B1C62 is a manufacturer-specific body diagnostic trouble code recorded for Land Rover vehicles. It belongs to the B-prefix family of codes, which covers body, interior, airbag, or comfort-electronics faults.

When B1C62 is stored, the module has detected an electrical-circuit fault in the wiring, connector, or driver associated with the named component.

Scanning & clearing: Body (B) codes are often stored in the body control module, airbag module, or climate module. A basic OBD-II tool usually will not read body codes — an enhanced or OEM-level scan tool is typically required.

B1C62 is a manufacturer-specific code. The same code string on a different make may have a different meaning. Always confirm the code's definition against the vehicle's service information for the specific make and model under test.

Code Information

The Body Control Module (BCM) on Land Rover vehicles uses a battery saver relay to control power to non essential accessory loads such as interior courtesy lighting, accessory sockets, and certain comfort circuits. The BCM commands the relay to drop these loads after a calibrated delay once the ignition is off, which prevents the battery from being discharged if a load is left active. DTC B1C62 is set when the BCM detects an electrical fault on the battery saver relay output (load side) circuit, such as an open circuit, short to ground, or short to battery, or when the measured output voltage ...
