C0196 Yaw Rate Sensor Circuit
C0196 is absent from the accessible J2012 lists, yet it is the yaw rate code of GM and Saab and is also used by Karma. The Saab 9-5 sets it when the sensor output leaves 0.25–4.75 V for longer than 0.1 s or its 2.1–2.9 V reference strays for 0.2 s; GM's multi-axis sensor reports 00 for a faulty signal and 5A when offset or plausibility against lateral acceleration, steering angle and speed fail. GM bulletin 15-05-25-001 traces C0196-5A on 2014–2016 full-size trucks and SUVs to stone hits that make the sensor in the airbag module resonate at 12–14 kHz. GM (Volt, ELR) and Karma (Revero 2017–2018) report it after transport on a carrier, when the car senses motion without wheel speed; a relearn, rest and a drive above 20 mph clear it.
Likely causes
Symptoms
