TROUBLE DIAGNOSIS
Revision: 2006 November2007 350Z
5. CHECK SHIFT-UP D4 → D5
Press down the accelerator pedal about half-way and inspect if the vehicle shifts up (D4 → D5 ) at the appro-
priate speed. Refer to AT- 5 8 , "
Vehicle Speed at When Gears Shifting Occurs" .
With CONSULT-III
Read the gear position, throttle position, and vehicle speed. Refer to AT- 8 8 , "
DATA MONITOR MODE" .
Does the A/T shift-up D
4 → D5 at the correct speed?
YES >> GO TO 6.
NO >> Enter a check mark at AT- 1 8 9 , "
A/T Does Not Shift: D4 → D5" on the AT- 4 4 , "DIAGNOSTIC
WORKSHEET" , then continue the road test.
6. CHECK LOCK-UP
When releasing accelerator pedal (closed throttle position signal: OFF) from D
5 , check lock-up from D5 to L/
U. Refer to AT- 5 8 , "
Vehicle Speed at When Gears Shifting Occurs" .
With CONSULT-III
Select “TCC SOLENOID” with the “MAIN SIGNALS” mode for “A/T”. Refer to AT- 8 4 , "
CONSULT-III REFER-
ENCE VALUE" .
Does it lock-up?
YES >> GO TO 7.
NO >> Enter a check mark at AT- 1 9 1 , "
A/T Does Not Lock-up" on the AT- 4 4 , "DIAGNOSTIC WORK-
SHEET" , then continue the road test.
7. CHECK LOCK-UP HOLD
Check hold lock-up.
With CONSULT-III
Select “TCC SOLENOID” with the “MAIN SIGNALS” mode for “A/T”. Refer to AT- 8 4 , "
CONSULT-III REFER-
ENCE VALUE" .
Does it maintain lock-up status?
YES >> GO TO 8.
NO >> Enter a check mark at AT- 1 9 3 , "
A/T Does Not Hold Lock-up Condition" on the AT- 4 4 , "DIAGNOS-
TIC WORKSHEET" , then continue the road test.
8. CHECK LOCK-UP RELEASE
Check lock-up cancellation by depressing brake pedal lightly to decelerate.
With CONSULT-III
Select “TCC SOLENOID” with the “MAIN SIGNALS” mode for “A/T”. Refer to AT- 8 4 , "
CONSULT-III REFER-
ENCE VALUE" .
Does lock-up cancel?
YES >> GO TO 9.
NO >> Enter a check mark at AT- 1 9 4 , "
Lock-up Is Not Released" on the AT- 4 4 , "DIAGNOSTIC WORK-
SHEET" , then continue the road test.
9. CHECK SHIFT-DOWN D5 → D4
Decelerate by pressing lightly on the brake pedal.
With CONSULT-III
Read the gear position and engine speed. AT- 8 8 , "
DATA MONITOR MODE" .
When the A/T shift
-down D5 → D4 , does the engine speed drop smoothly back to idle?
YES >> 1. Stop the vehicle.
2. Go to AT- 5 7 , "
Cruise Test — Part 2" .
NO >> Enter a check mark at AT- 1 9 5 , "
Engine Speed Does Not Return to Idle" on the AT- 4 4 , "DIAG-
NOSTIC WORKSHEET" , then continue the road test. Go to AT- 5 7 , "Cruise Test — Part 2" .

1. MANUAL MODE FUNCTION
Move to manual mode from “D” position.
Does it switch to manual mode?
YES >> GO TO 2.
NO >> Continue road test and add check mark to AT- 1 9 6 , "
Cannot Be Changed to Manual Mode" on the
AT- 4 4 , "
DIAGNOSTIC WORKSHEET" .
2. CHECK SHIFT-DOWN
During manual mode driving, is downshift from M
5 → M4 → M3 → M2 → M1 performed?
With CONSULT-III
Read the gear position. Refer to AT- 8 8 , "
DATA MONITOR MODE" .
Is downshifting correctly performed?
YES >> GO TO 2.
NO >> Enter a check mark at “A/T Does Not Shift” at the corresponding position (5th → 4th, 4th → 3rd,
3rd → 2nd, 2nd → 1st) on the AT- 4 4 , "
DIAGNOSTIC WORKSHEET" , then continue the road test.
3. CHECK ENGINE BRAKE
Check engine brake.
Does engine braking effectively reduce speed in M
1 position?
YES >> 1. Stop the vehicle.
2. Perform self-diagnostics. Refer to AT- 8 6 , "
SELF-DIAGNOSTIC RESULT MODE" , AT- 9 2 ,
"Diagnostic Procedure Without CONSULT-III" .
NO >> Enter a check mark at AT- 2 0 2 , "
Vehicle Does Not Decelerate by Engine Brake" on the AT- 4 4 ,
"DIAGNOSTIC WORKSHEET" , then continue trouble diagnosis.
