Nissan Armada 2025-2026 Service and Repair Manual: Normal Operating Condition
| Symptom | Result |
|---|---|
| Brake pedal slightly vibrates and operation sound (motor sound and sound from suspension) occurs when VDC function, TCS function, ABS function, EBD function, brake limited slip differential (BLSD) function, brake assist function, hill start assist function, or advanced hill descent control function operates. | This is not a malfunction, The symptom occurs VDC function, TCS function, ABS function, EBD function, brake limited slip differential (BLSD) function, brake assist function, hill start assist function, and advanced hill descent control function that are normally operated. |
| Brake stopping distance may become longer than models without ABS function depending on the road conditions, when ABS function is operated on slippery road like rough road, gravel road or snowy road. | |
| Brake pedal vibrates and operation sound occurs during sudden acceleration and cornering, when VDC function, TCS function, hill start assist function and brake limited slip differential (BLSD) function is operated. | |
| Brake pedal vibrates and motor sound from the engine room occurs, when the engine starts or the vehicle starts just after starting the engine | This is not a malfunction. The symptom occurs during the brake fluid accumulation in the accumulator and operational check of the ABS actuator and electric unit (control unit). |
| Acceleration may be felt insufficient depending on the road conditions. | This is not a malfunction. The symptom occurs TCS function that puts the highest priority to obtain the optimum traction (stability). |
| TCS may operate momentarily, while driving on a road where friction coefficient varies, or when downshifting or fully depressing accelerator pedal. | |
| ABS warning lamp and VDC warning lamp may turn ON, when the vehicle is on a rotating turntable or is given a strong shaking or large vibrations 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. In that case, erase selfdiagnosis result memory for “ABS” with CONSULT. |
| VDC warning lamp may turn ON and VDC function, TCS function, hill start assist function and brake limited slip differential (BLSD) function may not normally operate, when driving on a special road the is extremely slanted (bank in a circuit course). | |
| A malfunction in yaw rate/side/decel G sensor system may be detected when the vehicle sharply turns during a spin turn, acceleration turn or drift driving while VDC function and TCS function are OFF (VDC OFF switch is pressed and VDC OFF indicator lamp is in ON status). | |
| The vehicle speed does not increase, when the accelerator pedal is depressed while the vehicle is on a 2-wheel chassis dynamometer for speedometer check. | This is not malfunction. (When checking the vehicle on a chassis dynamometer, operate VDC OFF switch so that TCS function is OFF.) |
