C1104 on Nissan by model: symptoms, diagnosis and fix
The ABS/VDC control unit stores a wheel speed sensor code (C1101-C1104). Nissan's bulletin lists sensor damage, a missing sensor signal, short circuits and bent, corroded or contaminated connector pins as the things to check. 2007-2013 Nissan vehicles equipped with ABS/VDC, which includes the 2007-2012 Altima.
How to Fix
Per Nissan bulletin NTB10-102a, the technician records the active codes, clears them and road-tests above 13 mph to confirm the code returns, then checks the suspect sensor for damage, its output with a wheel sensor tester, the harness for shorts and the connectors for bent pins or corrosion before replacing anything. Nissan says not to replace a sensor based on the code alone. Normal warranty rules apply; this is not a recall or a promise of free repair. A stored code alone does not establish a failed sensor. The sensor, harness or connector repair follows the diagnostic result; do not infer that driving with a brake warning is safe.

Frequently asked questions
What does C1104 mean on a Nissan?
C1104 stands for "Manufacturer-Specific Chassis/ABS Circuit Code." C1104 is a manufacturer-specific chassis code whose meaning varies by maker; on many vehicles it falls within the ABS wheel-speed sensor circuit group, and on others it is associated with a traction/ABS lamp or related circuit fault. In general the chassis control module has detected an electrical problem (such as a short or open) in a circuit it monitors. Setting this code typically affects ABS and traction/stability control and lights the related dashboard warnings. Verify the precise definition for your specific make and model with a capable scan tool or factory service data before repairs. On Nissan it is documented across 1 model: Altima.
What are the most common causes of C1104?
The most common causes of C1104 are: Wheel speed sensor circuit fault (on makes that use it), Wiring or connector damage / corrosion, Short to power or short to ground in the circuit, Faulty sensor or warning lamp circuit component, ABS/stability control module fault, Poor ground or low system voltage. The specific cause varies by vehicle.
How much does it cost to fix C1104 on a Nissan?
Repair costs vary widely with the root cause and Nissan model; each issue on this page carries its own estimate where one is published.
