C1179 on Nissan by model: symptoms, diagnosis and fix
The stop-lamp (brake light) switch becomes contaminated by silicone off-gassing from grease used on nearby components. Electrical arcing oxidizes the contacts and builds up silicon dioxide, opening the circuit. The result is brake lights that do not illuminate (a rear-end-collision hazard) and, because the same switch signals the shift interlock, an inability to shift the transmission out of Park. Nissan recalled 807,376 Sentras under campaign PM971 (NHTSA 21V-135).
Common Symptoms
- Brake lights do not illuminate when pedal is pressed
- Brake lights stuck on
- Cannot shift out of Park
- Cruise control inoperative
- Intermittent push-button start issues
How to Fix
Have the dealer perform recall PM971 / 21V-135: replace the stop lamp switch and install a protective grommet at no cost. Outside the recall, the switch is an inexpensive part; confirm by checking whether brake lights work and whether the brake-pedal-press releases the shift interlock before condemning the shifter assembly.

The TA60 brake booster carries an integral delta stroke sensor that reports pedal travel versus booster assist to the ABS/VDC control unit. When that sensor drifts or the ABS actuator software misinterprets it, the system thinks the driver has made a panic input and cycles ABS at low speed on dry pavement. Owners describe the pedal going long and grabby, a shudder and grinding through the pedal at 5-10 mph, the front end feeling like it is going to fall off during a normal stop, and the BRAKE and ABS lights coming on with C1179 stored. The delta stroke sensor is not sold separately - it comes as part of the booster assembly. This complaint sits behind the class action settlement over the 2004-2008 Titan/Armada/QX56 brake system.
Common Symptoms
- ABS activates at low speed on dry pavement
- Grinding or shuddering felt through the brake pedal when stopping
- Brake pedal feels soft or travels farther than normal
- BRAKE and ABS warning lights illuminated
- Extended stopping distance
- Slip/VDC light on
How to Fix
Scan the ABS/VDC unit for C1179 first. Nissan's service path is to verify the ABS/VDC actuator has the current part number and reprogram it if not; if the fault persists, replace the brake booster assembly (which carries the delta stroke sensor) and in some cases the ABS actuator/control unit. Bleed the system properly with a scan tool that can cycle the ABS pump afterward. This is a separate fault from warped rotors - resurfacing rotors will not clear C1179, and the sensor cannot be replaced on its own.

Frequently asked questions
What does C1179 mean on a Nissan?
C1179 stands for "Delta Stroke Sensor Malfunction." A Nissan/Infiniti chassis code (scan-tool text 'ABS DELTA S SEN NG'), most often seen on Titan, Armada and QX56 models fitted with the active brake booster. The delta stroke sensor sits on the brake booster assembly and reports booster/pushrod stroke relative to pedal input, which the ABS/VDC control unit uses for brake assist; C1179 sets when that signal is out of range, shorted, or open. Expect the ABS, VDC/SLIP and brake warning lights to come on with stability control and brake assist disabled. Base hydraulic braking usually still works, but pedal feel and stopping distances can change, so this should be diagnosed promptly. Note that a Nissan service bulletin (NTB06-040) calls for a VDC control unit reprogram on some vehicles before condemning parts. On Nissan it is documented across 2 models: Sentra, Armada.
What are the most common causes of C1179?
The most common causes of C1179 are: Failed delta stroke sensor on/inside the brake booster (typically replaced as a booster assembly), Open, shorted, or chafed delta stroke sensor harness, Corroded or loose connector at the sensor or ABS actuator/control unit, Booster vacuum leak or internal booster fault, ABS actuator and electric unit (control unit) fault, or control unit software needing the TSB reprogram. The specific cause varies by vehicle.
How much does it cost to fix C1179 on a Nissan?
Published repair estimates on Nissan range from $400 to $2,200 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
