B0960 does not appear in the accessible J2012 lists; it is documented by GM and the GM-era Saab models as the right middle rear parking sensor. The 2011 Saab 9-5 and 9-4X list B0960 01 (short to battery), 06 (low voltage or open), 08 (invalid signal), 21 (incorrect period) and 3A (wrong part fitted); B0958, B0959 and B0961 cover the other rear sensors. The older 9-3 uses B0960 for its right centre distance sensor and checks it with reverse gear engaged and more than 9 V; on a fault the system stops measuring and mutes the warning tones. Bosch explains that such sensors emit short ultrasonic pulses and pass the echoes to a central unit, measuring up to 5.5 m. The horn relay, by contrast, is monitored by the same makers as B2750.

Bumper harness damaged after a parking knock or repair
