MECHANICAL SYSTEM TESTS
1. STALL SPEED TEST
HINT:
This test is to check the overall performance of the engine and transaxle.
CAUTION:
NOTICE:
(a) Connect the Techstream to the DLC3.
(b) Run the vehicle until the transmission fluid temperature has reached 50 to 80°C (122 to 176°F).
(c) Allow the engine to idle with the air conditioning and headlights off.
(d) Chock all 4 wheels.
(e) Set the parking brake and keep the brake pedal depressed firmly with your left foot.
(f) Move the shift lever to D.
(g) Depress the accelerator pedal as much as possible with your right foot.
(h) Read the engine rpm (stall speed) and release the accelerator pedal immediately.
Standard value:
Stall Speed |
|
---|---|
2680 rpm |
+ 200 rpm |
- 460 rpm |
Test Result |
Possible Cause |
---|---|
Stall speed is lower than standard value |
HINT: If the value is less than the specified value by 600 rpm or more, the torque converter could be faulty. |
Stall speed is higher than standard value |

2. SHIFT TIME LAG TEST
HINT:
When the shift lever is moved while the engine is idling, there will be a certain time lapse or lag before the shock can be felt. This is used for checking the condition of the clutch, and brake.
(a) Connect the Techstream to the DLC3.
(b) Run the vehicle until the transmission fluid temperature has reached 50 to 80°C (122 to 176°F).
(c) Allow the engine to idle with the air conditioning off.
(d) Set the parking brake and keep the brake pedal depressed firmly.
(e) Check the D position time lag.
(1) Move the shift lever to N and wait for 1 minute.
(2) Move the shift lever to D and measure the time until the shock is felt.
(3) Repeat the 2 steps above 3 times, and calculate the average time of the 3 tests.
(f) Check the R position time lag.
(1) Move the shift lever to N and wait for 1 minute.
(2) Move the shift lever to R and measure the time until the shock is felt.
(3) Repeat the 2 steps above 3 times, and calculate the average time of the 3 tests.
Standard value:
D position time lag is less than 1.2 seconds
R position time lag is less than 1.5 seconds
Evaluation (If N to D or N to R time lag is longer than the specified time)
Test Result |
Possible Cause |
---|---|
D position time lag exceeds standard value |
|
R position time lag exceeds standard value |
