Road Test - Mazda Mazda6 Workshop Manual Supplement

Time Lag Test
1. Perform mechanical system test preparation. (See
2. Start the engine.
3. Warm up the engine until the ATF temperature reaches 60—70°C {140—158°F}. Shift the selector lever from N
position to D range.
4. Use a stopwatch to measure the time it takes from shifting until engagement is felt. Take three measurements
for each test and average the results using the following formula.
Formula
Average time lag = (Time 1 + Time 2 + Time 3) / 3
5. Perform the test for the following shifts in the same manner.
• N position → P position
Time lag
N → D range ... approx. 0.5—1.0 second
N → R position ... approx. 0.6— 1.0 second
Evaluation of time lag test
Condition

Road Test Preparation
1. Inspect the engine coolant. (See Section E.)
2. Inspect the engine oil. (See
3. Inspect the ATF levels. (See
4. Inspect the idle speed and ignition timing in P position. (See
5. Bring up the engine and transaxle to normal operating temperature.
