# Service bulletin 04\-007\-18\-3500

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

## NHTSA's summary

Some vehicles may experience the TCS/DSC indicator light and the TPMS warning light both ON with DTC C0051:62 stored in memory.DTC C0051:62 \- The difference between the initial learned value of the steering angle \(as calculated by each sensor\) and the steering angle \(as calculated by the steering angle sensor\) while driving in a straight line, has exceeded its allowable tolerance \(or threshold\). NOTE: For vehicles equipped with the Smart City Brake System \(SCBS\), the master warning light also comes ON with the message "SCBS Inspection Required" in the display. The symptoms may occur when the following conditions are met: After starting the engine, the vehicle is driven backwards while the steering wheel is turned to the left or to the right or going forward over a bump while turning the steering wheel. The vehicle is then driven forward and begins accelerating while the steering wheel is still turned. To eliminate this concern, the DSC HU/CM software has been changed.

Noise, Vibration, and Harshness \(NVH\) Diagnostic Guidelines Diagnostic Guidelines When diagnosing NVH concerns, it is essential to first classify the issue into one of three primary categories: Noise, Vibration, or Harshness. Many customer complaints may involve overlapping symptoms, such as both noise and vibration, so identifying the dominant characteristic is critical. Once the primary symptom is determined, follow the appropriate diagnostic path. For example, if a concern includes both noise and vibration but is related to vehicle speed, the vibration diagnostic path should be followed. When considering component replacement during the diagnostic process, it is best practice to start with the lowest cost or most accessible part unless diagnostic evidence clearly identifies a more expensive or complex component as the root cause. This approach helps minimize repair costs and avoids unnecessary part replacements. For example, a growling or bearing whine noise may be mistakenly attributed to internal components in the differential, transfer unit, or transmission, when the actual source is a wheel bearing. Misdiagnosis like this can lead to unnecessary repairs, added time and cost. To help prevent this, always follow the guidelines in the repair procedure.

Mazda has developed factory recommended scheduled maintenance services that support all major vehicle systems. Mazda recommends dealers follow the scheduled maintenance tables as cited in the vehicle\-specific workshop manual or owner's manual. Services performed outside of Mazda's factory scheduled maintenance are not recommended. These services are unnecessary and create unneeded expenses for your customers.
- [06\-001\-24](/bulletins/10249497.md), 2024-02-01, Service bulletin: STEERING. Some customers may complain about a creaking, knocking, rattle or clunk noise coming from the steering column while driving. A steering column nut loosens due to excessive load when driving on irregular roads. To eliminate this concern, the tightening torque for the steering column nut has been increased.
