- How the car detects it
- C0515 says the right rear sensor circuit draws or sees too much. GM's 2025 tables bundle four ASIC flags under this code: high-side current above 40 mA, high side shorted to battery, low-side overcurrent and, perhaps unexpectedly, a low side shorted to ground; each sets it after 100 ms as Type A. The 2023 tables keep it simpler: 50 mA exceeded for 0.12 s in the signal wire. Mitsubishi's C1067-12 equals C0515 and is described as a short circuit found within one second. GM's Silverado EV bulletin 24-NA-125 lists C0515 among the codes caused by the ABS harness touching the rear drive unit. A sensor shorted inside its housing is the other common source of overcurrent.
