TROUBLE DIAGNOSIS
Revision: 2005 July 2005 FX
6. CHECK “R” POSITION FUNCTIONS
1. Engage the brake.
2. Move selector lever to “R” position.
3. Disengage the brake for 4 to 5 seconds.
Does the vehicle creep backward?
YES >> GO TO 7.
NO >> Enter a check mark at “Vehicle Does Not Creep Backward In “R” Position” on the AT- 4 7 , "
DIAG-
NOSTIC WORKSHEET" , then continue the road test.
7. CHECK “D” POSITION FUNCTIONS
Inspect whether the vehicle creep forward when the transmission is put into the “D” position.
Does the vehicle creep forward in the
“D” position?
YES >> Go to AT- 5 8 , "Cruise Test - Part 1" , AT- 6 0 , "Cruise Test - Part 2" , and AT- 6 1 , "Cruise Test - Part
3" .
NO >> Enter a check mark at “Vehicle Does Not Creep Forward In “D” Position” on the AT- 4 7 , "
DIAG-
NOSTIC WORKSHEET" , then continue the road test.
Cruise Test - Part 1ACS002M1
1. CHECK STARTING OUT FROM D1
1. Drive the vehicle for about 10 minutes to warm up the engine oil and ATF. Appropriate temperature for the ATF: 50 to 80 °C (122 to 176 °F)
2. Park the vehicle on a level surface.
3. Move selector lever to “P” position.
4. Start the engine.
5. Move selector lever to “D” position.
6. Press the accelerator pedal about half way down to accelerate the vehicle.
With CONSULT-II
Read the gear positions. Refer to AT- 9 6 , "
DATA MONITOR MODE" .
Starts from D1?
YES >> GO TO 2.
NO >> Enter a check mark at “Vehicle Cannot Be Started From D1” on the AT- 4 7 , "
DIAGNOSTIC WORK-
SHEET" , then continue the road test.
2. CHECK SHIFT-UP D1 → D2
Press down the accelerator pedal about half-way and inspect if the vehicle shifts up (D1 → D2) at the appro-
priate speed.

Refer to AT- 6 2 , "Vehicle Speed at Which Gear Shifting Occurs" .
With CONSULT-II
Read the gear position, throttle degree of opening, and vehicle speed. Refer to AT- 9 6 , "
DATA MONITOR
MODE" .
Does the A/T shift-up D1
→ D2 at the correct speed?
YES >> GO TO 3.
NO >> Enter a check mark at “A/T Does Not Shift: D1 → D2” on the AT- 4 7 , "
DIAGNOSTIC WORK-
SHEET" , then continue the road test.
