Nissan Altima 2007-2012 Service Manual: Road test
Description
DESCRIPTION
• The purpose of the test is to determine overall performance of CVT and analyze causes of problems.
• The road test consists of the following three parts: 1. “Check Before Engine Is Started”TM-425.
2. “Check at Idle”TM-426.

6.CHECK “R” POSITION FUNCTION
Release foot brake for several seconds.
Does vehicle creep backward when foot brake is released? YES >> GO TO 7.
NO >> Refer toTM-400, "Symptom Table". Continue “Road Test”.
7.CHECK “D” POSITION FUNCTION
Move selector lever to “D” position and check if vehicle creeps forward.
Does vehicle creep forward in all positions? YES >> Go to TM-427, "Cruise Test".
NO >> Stop “Road Test”. Refer to TM-400, "Symptom Table".
Cruise Test
1.CHECK VEHICLE SPEED WHEN SHIFTING GEARS — PART 1
1. Drive vehicle for approximately 10 minutes to warm engine oil and CVT fluid up to operating temperature.
CVT fluid operating temperature: 50 – 80°C (122 – 176°F)
2. Park vehicle on flat surface.
3. Move selector lever to “P” position.
4. Start engine.
5. Move selector lever to “D” position.
6. Accelerate vehicle to 2/8-way throttle depressing accelerator pedal constantly.
Read vehicle speed and engine
speed. Refer to TM-451,
"Vehicle Speed When Shifting Gears".
OK or NG
OK >> GO TO 2.
NG >> Refer to TM-400, "Symptom Table". Continue “Road Test”.
2.CHECK VEHICLE SPEED WHEN SHIFTING GEARS — PART 2
1. Park vehicle on flat surface.
2. Move selector lever to “D” position.
3. Accelerate vehicle to full depression depressing accelerator pedal constantly.
Read vehicle speed and engine
speed.Refer to TM-451,
"Vehicle Speed When Shifting Gears".
OK or NG
OK >> GO TO 3.
NG >> Refer to TM-400, "Symptom Table". Continue “Road Test”.
3.CHECK MANUAL MODE FUNCTION
Move to manual mode from “D” position.
Does it switch to manual mode? YES >> GO TO 4.
NO >> Refer to TM-400, "Symptom Table". Continue “Road Test”.
4.CHECK SHIFT-UP FUNCTION
During manual mode driving, is upshift from M1 → M2 → M3 → M4 → M5 → M6 performed?
Read the gear position. Refer
to TM-298, "CONSULT-III Function (TRANSMISSION)".
Is upshifting correctly performed? YES >> GO TO 5.
NO >> Refer to TM-400, "Symptom Table". Continue “Road Test”.
