About B1534

B1534 is a manufacturer-specific body diagnostic trouble code recorded for Renault vehicles. It belongs to the B-prefix family of codes, which covers body, interior, airbag, or comfort-electronics faults.

When B1534 is stored, the module has detected a short-circuit (voltage pulled to ground or to supply) in the monitored circuit.

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.

B1534 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 B1534 fault code indicates that the Body Control Module (BCM) or memory seat module has detected a short to ground on the Memory 1 Switch input. The Memory 1 Switch is the recall button on the driver's door panel that returns the seat and mirrors to a stored position 1 setting. The module supplies a low reference voltage (typically 5V) to the switch input and expects to see ground only momentarily when the button is pressed; instead, the module is seeing a constant ground state on the line, which it interprets as either a stuck switch or a short. Symptoms include the memory recall function...
