B0600Mirror Adjustment Driver Side Circuit
- Generic OBD-II code · Body
- How the car detects it
- B0600 is not listed in the J2012 tables that are publicly accessible, and no manufacturer explains it. The title refers to the adjustment circuit of the driver's exterior mirror, which FMVSS 111 requires the driver to be able to tilt horizontally and vertically while seated. Saab's 9-3 monitors the two mirror motors in the driver door module: B1723 01 for the left/right output shorted to battery, B1724 02 for the up/down output shorted to ground, both evaluated only while the common motor line (B1600) is fault-free. The module then retries that axis four times per driving cycle. Memory mirrors also read the glass position; Britax's US6254242B1 uses a potentiometer linked directly to the glass for that.
