B0530Driver Door Lock Actuator Circuit
- Generic OBD-II code · Body
- How the car detects it
- B0530 does not appear in the publicly available J2012 lists. GM names it among the circuit keywords of PIP5094 without a descriptor, and the GM-era Saab 9-3 (2003–2012) uses B0530 for something else entirely: the left turn indicator. There the front electrical centre logs B0530 04 when the lamp draws under 50 mA, and the rear centre logs B0530 02 for a grounded output, after which the indicators flash at double rate. For the driver door lock motor named in the title, the same 9-3 uses its own numbers in the driver door module, B3135 02 (motor line grounded) and B3130 02 (common line), both leaving central locking dead. HELLA lists supply, ground, broken wires and stiff lock mechanics as typical actuator faults.
