A: PROCEDURE

For troubleshooting, there are several driving patterns shown below. 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 fuel remains approx. half [20 — 40

(5.3 — 10.6 US

gal, 4.4 — 8.8 Imp gal)].

2) After performing the diagnostics and clearing the memory, check for any remaining unresolved trouble da-

ta. <Ref. to EN(H4SO U5)(diag)-46, Clear Memory Mode.>

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 diagnosis twice if the DTC marked with *. After completing the first diagnosis, stop the engine

and perform second diagnosis in same condition.

2. DRIVE CYCLE A (AFTER RUNNING 20 MINUTES AT

0 KM/H (50 MPH), IDLE THE ENGINE

FOR 1 MINUTE.)
