PROCEDURE
| PROCEDURE |
There are three drive patterns for the trouble diagnosis. Driving in the specified pattern allows to diagnose malfunctioning items listed below. After the malfunctioning items listed below are repaired, always check whether they correctly resume their functions by driving in the required drive pattern.
| PREPARATION FOR THE DRIVE CYCLE |
Make sure that the fuel remains approx. half amount [20 — 40 litres (5.3 — 10.6 US gal, 4.4 — 8.8 Imp gal)], and battery voltage is 12 V or more.
Separate the test mode connector.
| Note | ||
| • |
Except for the engine coolant temperature
specified items at starting, the diagnosis is carried out after
engine warm up.
|
|
| • |
Carry out the diagnosis which is marked* on
DTC twice, then, after finishing first diagnosis, stop the engine and
do second time at the same condition.
|
|
| AFTER RUNNING 20 MINUTES AT 80 KM/H (50 MPH), IDLE ENGINE FOR 1 MINUTE. |
