TCM
Reference Value
CONSULT DATA MONITOR STANDARD VALUE
NOTE:
Therefore, if there is an obvious difference between the shift timing estimated from a shift shock (or engine speed variations) and that shown on the CONSULT, the mechanism parts (including the hydraulic circuit) excluding the solenoids and sensors may be malfunctioning. In this case, check the mechanical parts following the appropriate diagnosis procedure.
This is due to the following reasons.
*: This monitor item does not use.
Terminal layout
Input/output signal standard
Fail-Safe
Tcm has a fail-safe mode. The mode functions so that operation can be continued even if the signal circuit of the main electronically controlled input/output parts is damaged.
If the vehicle shows following behaviors including “poor acceleration”, a malfunction of the applicable system is detected by tcm and the vehicle may be in a fail-safe mode. At this time, check the dtc code and perform inspection and repair according to the malfunction diagnosis procedures.
Fail-safe function
Protection control
The tcm becomes the protection control status temporarily to protect the safety when the safety of tcm and transmission is lost. It automatically returns to the normal status if the safety is secured.
The tcm has the following protection control.
CONTROL FOR WHEEL SPIN
Control | When a wheel spin is detected, the engine output and gear ratio are
limited and the line pressure is increased.
At the 1gr, the clutch pressure is increased. |
Vehicle behavior in control | If the accelerator is kept depressing during wheel spin, the engine revolution and vehicle speed are limited to a certain degree. From the 1gr, upshift to a certain gear ratio is only allowed. |
Normal return condition | Wheel spin convergence returns the control to the normal control.V |
Control when fluid temperature is high
Control | When the cvt fluid temperature is high, the gear shift permission maximum revolution and the maximum torque are reduced than usual to prevent increase of the oil temperature. |
Vehicle behavior in control | Power performance may be lowered, compared to normal control. |
Normal return condition | The control returns to the normal control when CVT fluid temperature is lowered. |
Torque is reduced when driving with the reverse gear
Control | Engine output is controlled according to a vehicle speed while reversing the vehicle. |
Vehicle behavior in control | Power performance may be lowered while reversing the vehicle. |
Normal return condition | Torque returns to normal by positioning the selector lever in a range other than “R” position. |
Reverse prohibit control
Control | The reverse brake is controlled to avoid becoming engaged when the selector lever is set in “r” position while driving in forward direction at more than the specified speed. |
Vehicle behavior in control | If the selector lever is put at “r” position when driving with the forward gear, the gear becomes neutral, not reverse. |
Normal return condition | The control returns to normal control when the vehicle is driven at low speeds. (The reverse brake becomes engaged.) |

Reporting safety defects
For USA
If you believe that your vehicle has a defect
which could cause a crash or could
cause injury or death, you should immediately
inform the National Highway Traffic
Safety Administration (NHTSA) in addition
to notifying NISSAN.
If NHTSA receives similar complaints, it
may open an inv ...
