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

Description
DTC B142A IGNITION VOLTAGE
Ignition voltage is supplied to the air bag diagnosis sensor unit when the
ignition is in the ON position. The air
bag diagnosis sensor unit will monitor for low or high ignition voltage.
