VALUES ON THE DIAGNOSIS TOOL

In CONSULT-III, the electrical shift timing, which is the operation timing of each solenoid, is displayed. 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-III, the mechanical 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.
Shift point (gear position) displayed on CONSULT-III slightly differs from shift pattern described in Service Manual. This is due to the following reasons.

Actual shift pattern may vary slightly within specified tolerances.
While the shift pattern described in Service Manual indicates start of each shift, CONSULT-III shows gear position at the end of shift.
CONSULT-III display of each solenoid (ON–OFF) changes at the start of shifting. Display of gear position changes at the end of shifting that is calculated by the control unit.

■ CAUTION ■
Each measurement must be performed at the transmission oil temperature of 50°C (122°F) or more.

Fail Safe

PRECAUTION REGARDING FAIL SAFE FUNCTIONS

TCM has the electrical fail safe mode. The mode functions so that the operation can be continued even if the signal circuit of the main electronically controlled input/output parts is damaged.
Even if the electronic circuit is normal, the fail safe mode may start under special conditions (such as when the brake pedal is depressed suddenly from a hard wheel spin status to stop rotation of wheels). In this case, turn the ignition switch OFF and back to ON after 5 seconds to resume the normal shift pattern.
Consequently, the customer's vehicle may already returns to normal condition. Refer to Work Flow (GT-R certified NISSAN dealer). Following are results of self-diagnosis.

FAIL SAFE FUNCTION

If a malfunction occurs in either of the sensors or solenoids, this function controls the normal operation without downgrading the drivability.

*1: The fail safe mode operates if an error is detected in the TCM internal diagnosis.
*2: The fail safe mode operates if an error is detected in the sensor power supply voltage diagnosis.
*3: The fail safe mode operates if an engine torque error signal is detected.
*4: The fail safe mode operates if an engine speed error signal is detected.
DTC No.	The transmission operates under the fail safe mode
P0700^*1 P0705	Release the clutches A and B if an error is detected. The driving force is not transmitted caused by this. The vehicle cannot be driven.
P0770 P0882	Driving gear	Fixed into the driving gear to get the vehicle driven, if an error occurs. When the vehicle starts again after it is stopped, it becomes the following conditions.
		Driving gear when the error occurs		Restart
		1st gear		Possible to drive forward only (fixed into 1st gear)
		2nd gear		Only moving forward is possible (fixed into 2nd gear)
		3rd gear, 4th gear, 5th gear, 6th gear, Neutral, Not identified		Impossible
		Reverse		Only moving rearward is possible (fixed into Reverse gear)
	Driving mode	The M range driving is prohibited. (During M range driving, the vehicle is forcibly shifted to the A range driving) Selecting the set-up switch is prohibited. (If SNOW or R is selected, the vehicle is forcibly set to Normal)
	Vehicle speed	The engine torque is restricted by the driving gear when the error occurs, and then the vehicle speed (maximum speed) is restricted.
		Driving gear when the error occurs		Vehicle speed　km/h (MPH)
		1st gear, 2nd gear		46 (29)
		3rd gear, 4th gear		85 (53)

P0700^*2 P0715 P0729 P0732 P0745 P0746 P0750 P0755 P0795 P0797 P0840	Driving gear	Release the clutch A and prohibit the using of even gears (2nd gear, 4th gear, and 6th gear). During driving, shift up or down to the next gear (odd gear) according to the driving conditions, and then shift the gear and drive the vehicle using the odd gears (1st gear, 3rd gear, 5th gear, and Reverse gear). Shift to 5th gear after decelerating the vehicle speed to prevent over rev during driving at 6th gear.
	Driving mode	The M range driving is prohibited. (During M range driving, the vehicle is forcibly shifted to the A range driving). Selecting the set-up switch is prohibited. (If SNOW or R is selected, the vehicle is forcibly set to Normal).
	Vehicle speed	The engine torque is restricted by the driving gear when the error occurs, and then the vehicle speed (maximum speed) is restricted.
		Driving gear when the error occurs		Vehicle speed　km/h (MPH)
		2nd gear		46 (29)
		4th gear		85 (53)
		6th gear		134 (84)
		Neutral		134 (84)
		Not identified		46 (29)
P0700^*2 P0731 P0733 P0760 P0765 P0775 P0776 P0845 P2713 P2714 P2765	Driving gear	Release the clutch B and prohibit the using of odd gears (1st gear, 3rd gear, 5th gear) and reverse gear. During driving, shift up or down to the next gear (even gear) according to the driving conditions, and then shift the gear and drive the vehicle using the even gears (2nd gear, 4th gear, 6th gear). Shift to the neutral conditions when the error is detected during driving at reverse gear. Shift to 2nd gear when the error is detected during driving at 1st gear.
	Driving mode	The M range driving is prohibited. (During M range driving, the vehicle is forcibly shifted to the A range driving.) Selecting the set-up switch is prohibited. (If SNOW or R is selected, the vehicle is forcibly set to Normal.)
	Vehicle speed	The engine torque is restricted by the driving gear when the error occurs, and then the vehicle speed (maximum speed) is restricted.
		Driving gear when the error occurs		Vehicle speed　km/h (MPH)
		1st gear		46 (29)
		3rd gear		85 (53)
		5th gear		134 (84)
		Reverse		46 (29)
		Neutral		134 (84)
		Unknown		46 (29)
P0700^{3, 4} P0705 P1705	Driving gear	The use of all gears becomes possible.
	Driving mode	The M range driving is prohibited. (During M range driving, the vehicle is forcibly shifted to the A range driving.) Selecting the set-up switch is prohibited. (If SNOW or R is selected, the vehicle is forcibly set to Normal.)
	Vehicle speed	Restrict or fix the engine torque and fix the throttle position according to the detected DTC.
		DTC	Engine torque		Throttle position
		P0700^*3	Fixed		Approximately 1/8 fixed
		P0700^*4	Restricted		As per usual
		P0705	Restricted		As per usual
		P1705	Fixed		Approximately 1/8 fixed
