ENGINE (DIAGNOSTICS)(H4SO) > Drive Cycle

OPERATION

There are three driving patterns on diagnostic. Driving in the specified pattern allows to diagnose malfunctioning items listed below. After the repair of the following trouble items, be sure to drive the vehicle with the specified drive patterns to check whether the function is resumed correctly.

1. PREPARATION FOR DRIVE CYCLE

1. Check that the battery voltage is 12 V or more and approx. half of fuel remains [20 — 40 L (5.3 — 10.6 US gal, 4.4 — 8.8 Imp gal)].

2. After clearing the memory, check for any remaining unresolved trouble data.

3. Disconnect the test mode connector.

NOTE:

Perform the diagnosis after warming up the engine except when the engine coolant temperature at starting is specified.

Perform the diagnostic twice when the DTC is marked with *. After the completion of the first diagnostic, stop the engine and perform the second diagnostic on same condition.

2. AFTER RUNNING 20 MINUTES AT 80 KM/H (50 MPH), IDLE THE ENGINE FOR 1 MINUTE.
