MECHANICAL SYSTEM TESTS 1. STALL SPEED TEST HINT: This test is to check the overall performance of the engine and transmission. CAUTION:
NOTICE:
(a) Connect the Techstream to the DLC3. (b) Turn the ignition switch to ON. (c) Turn the Techstream on. (d) Enter the following menus: Powertrain / Engine and ECT / Data List. (e) Run the vehicle until the transmission fluid temperature is between 50 and 80°C (122 and 176°F). (f) Allow the engine to idle with the air conditioning off. (g) Chock all 4 wheels. (h) Set the parking brake and keep the brake pedal depressed firmly with your left foot. (i) Move the shift lever to D. (j) Depress the accelerator pedal as much as possible with your right foot. (k) Read the engine speed (stall speed) and release the accelerator pedal immediately. Standard value: 2300 +/-200 rpm Evaluation
NOTICE: Perform the test while the ATF temperature is 50 to 80°C (122 to 176°F). 2. SHIFT TIME LAG TEST HINT: This test is to check the condition of the direct clutch, forward clutch, 1st brake and reverse brake. (a) Connect the Techstream to the DLC3. (b) Turn the ignition switch to ON. (c) Turn the Techstream on. (d) Enter the following menus: Powertrain / Engine and ECT / Data List. (e) Run the vehicle until the transmission fluid temperature is between 50 and 80°C (122 and 176°F). (f) Allow the engine to idle with the air conditioning off. (g) Set the parking brake and keep the brake pedal depressed firmly. (h) 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 procedures above 3 times, and then calculate the average time of the 3 tests. (i) 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 procedures above 3 times, and then 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
