Mechanical System Tests
MECHANICAL SYSTEM TESTS1. STALL SPEED TEST
HINT: This test is to check the overall performance of the engine and transaxle by measuring the stall speeds in the D position.
NOTICE:
^ Do not perform the stall speed test for longer than 5 seconds.
^ To ensure safety, perform this test in a wide, clear level area which provides good traction.
^ The stall speed test must always be carried out by pairs of technicians. One technician must watch the wheels and wheel stoppers from outside the vehicle to make sure they do not slip, while the other performs the test.
(a) Connect the intelligent tester to the DLC3.
(b) Run the vehicle until the ATF (Automatic Transmission Fluid) temperature reaches 50° to 80°C (122° to 176°F).
(c) Allow the engine to idle with the air conditioning OFF.
(d) Chock all 4 wheels.
(e) Set the parking brake and keep the brake pedal firmly depressed with your left foot.
(f) Shift the shift lever to the D position.
(g) Depress the accelerator pedal all the way down with your right foot.
(h) Read the engine rpm (stall speed) and release the accelerator pedal immediately.
Standard value: 1,850 to 2,450 rpm

2. SHIFT TIME LAG TEST
HINT: This test is to check the conditions of the direct clutch, forward clutch, 1st brake and reverse brake.
(a) Connect the intelligent tester to the DLC3.
(b) Run the vehicle until the ATF (Automatic Transmission Fluid) temperature reaches 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 firmly depressed with your left foot.
(e) Check the D range time lag.
(1) Shift the shift lever into the N position and wait for 1 minute. (*1)
(2) Shift the shift lever into the D position and measure the time until the shock is felt. (*2)
(3) Repeat procedures (*1) and (*2) three times, and calculate the average time of the three tests.
(f) Check the R range time lag.
(1) Shift the shift lever into the N position and wait for 1 minute. (*3)
(2) Shift the shift lever into the R position and measure the time until the shock is felt. (*4)
(3) Repeat procedures (*3) and (*4) three times, and calculate the average time of the three tests.
Standard value:
D range time lag is less than 1.2 seconds
R range time lag is less than 1.5 seconds
