C1102 on Nissan
Manufacturer-Specific Chassis/ABS Sensor Code (commonly Wheel-Speed/Acceleration Switch Circuit)
C1102 on Nissan vehicles indicates manufacturer-specific chassis/abs sensor code (commonly wheel-speed/acceleration switch circuit). Au7o has documented this code across 1 Nissan model — most commonly on Altima. C1102 is a manufacturer-specific chassis code most often associated with an ABS input circuit. Depending on the make it can refer to a wheel-speed sensor circuit fault or an ABS acceleration (G-sensor) switch circuit failure that the control module has detected. When set it usually disables ABS and traction/stability control and illuminates the related warning lights, while normal (non-assisted) braking is still available. Confirm the exact definition for your vehicle with a capable scan tool or service manual, since the meaning differs by manufacturer. Typical repair costs on Nissan range from $250 to $700, depending on the specific model and root cause.
Common Causes of C1102
- •Faulty or contaminated wheel speed sensor
- •Faulty ABS acceleration / G-sensor (on makes that use it)
- •Damaged tone/reluctor ring
- •Wiring or connector damage in the circuit
- •Open or shorted sensor circuit
- •ABS/stability control module fault

- Front Wheel Bearing and Hub Failure Causing Humming Noise and ABS/Wheel Speed Issues2002-2012
A recurring higher-mileage Altima problem is front wheel bearing wear, often first noticed as a humming or growling noise that increases with road speed. As the bearing deteriorates, owners may feel vibration, looseness, or see ABS warnings if the integrated wheel speed signal becomes erratic. This is widely reported in repair databases and owner forums, especially on cars driven on rough roads.
