Nissan Sentra Service Manual: Normal operating condition
Description
| Symptom | Result |
| Slight vibrations are felt on the brake pedal and operation noises occur when VDC, TCS or ABS is activated. | This is a normal condition due to the VDC, TCS or ABS activation. |
| Stopping distance is longer than that of vehicles without ABS when the vehicle drives on rough, gravel, or snow-covered (fresh, deep snow) roads. | |
| The brake pedal moves and generates noises when TCS or VDC is activated due to rapid acceleration or sharp turn. | |
| The brake pedal vibrates and motor operation noises occur from the engine room after the engine starts and just after the vehicle starts. | TCS may activate momentarily if wheel speed changes when driving where road friction coefficient varies, when downshifting, or when fully depressing accelerator pedal. |
| Depending on the road conditions, the driver may experience a sluggish feel in the brake pedal. | This is normal, because TCS places the highest priority on the optimum traction (stability). |
| TCS may activate momentarily if wheel speed changes when driving where road friction coefficient varies, when downshifting, or when fully depressing accelerator pedal. | |
| The ABS warning lamp and SLIP indicator lamp may turn ON when the vehicle is subject to strong shaking or large vibration, such as when the vehicle is rotating on a turntable or located on a ship while the engine is running. | In this case, restart the engine on a normal road. If the normal condition is restored, there is no malfunction. At that time, erase the selfdiagnosis memory. |
| VDC may not operate normally or the ABS warning lamp, and SLIP indicator lamp may illuminate when driving on a road that is extremely slanted (e.g., bank in a circuit course). | |
| A malfunction may occur in the yaw rate/side/decel G sensor system when the vehicle turns sharply, such as during a spin turn, axle turn, or drift driving, while the VDC function is OFF (VDC OFF indicator lamp illuminated). | |
| The vehicle speed will not increase even though the accelerator pedal is depressed, when inspecting the speedometer on a 2-wheel chassis dynamometer. | Normal (Deactivate the VDC/TCS function before performing an inspection on a chassis dynamometer.) |
| SLIP indicator lamp may simultaneously turn ON when low tire pressure warning lamp turns ON. | This is not a VDC system error but results from characteristic change of tire. |
Vehicle jerks during vdc/tcs/abs
control
Diagnosis Procedure
1.SYMPTOM CHECK
Check if the vehicle jerks during VDC/TCS/ABS control.
Is the inspection result normal?
YES >> Inspection End.
NO >> GO TO 2

To judge the malfunction, the diagnosis checks that the A/F signal computed
by ECM from the A/F sensor 1
signal is not inordinately low.
