ON BOARD DIAGNOSTIC (OBD) SYSTEM

ON BOARD DIAGNOSTIC (OBD) SYSTEMPFP:00028
IntroductionNBS004JR
The ECM has an on board diagnostic system, which detects malfunctions related to engine sensors or actua-
tors. The ECM also records various emission-related diagnostic information including:
The above information can be checked using procedures listed in the table below.
× : Applicable —: Not applicable
*: When DTC and 1st trip DTC simultaneously appear on the display, they cannot be clearly distinguished from each other.
The malfunction indicator lamp (MIL) on the instrument panel lights up when the same malfunction is detected
in two consecutive trips (Two trip detection logic), or when the ECM enters fail-safe mode. (Refer to EC-756,
"Fail-Safe Chart" .)
Two Trip Detection LogicNBS004JS
When a malfunction is detected for the first time, 1st trip DTC and 1st trip Freeze Frame data are stored in the
ECM memory. The MIL will not light up at this stage. <1st trip>
If the same malfunction is detected again during the next drive, the DTC and Freeze Frame data are stored in
the ECM memory, and the MIL lights up. The MIL lights up at the same time when the DTC is stored. <2nd
trip> The “trip” in the “Two Trip Detection Logic” means a driving mode in which self-diagnosis is performed
during vehicle operation. Specific on board diagnostic items will cause the ECM to light up or blink the MIL,
and store DTC and Freeze Frame data, even in the 1st trip, as shown below.
× : Applicable —: Not applicable
When there is an open circuit on MIL circuit, the ECM cannot warn the driver by lighting up MIL when there is
malfunction on engine control system.

BASIC SERVICE PROCEDUREPFP:00018
Basic InspectionNBS0041P
1. INSPECTION START
1. Check service records for any recent repairs that may indicate a related malfunction, or a current need for scheduled maintenance.
2. Open engine hood and check the following:
–Harness connectors for improper connections
–Wiring harness for improper connections, pinches and cut
–Vacuum hoses for splits, kinks and improper connections
–Hoses and ducts for leaks
–Air cleaner clogging
–Gasket
3. Confirm that electrical or mechanical loads are not applied.
–Headlamp switch is OFF.
–Air conditioner switch is OFF.
–Rear window defogger switch is OFF.
–Steering wheel is in the straight-ahead position, etc.
4. Start engine and warm it up until engine coolant temperature indicator points the middle of gauge.
Ensure engine stays below 1,000 rpm.
5. Run engine at about 2,000 rpm for about 2 minutes under no load.
6. Make sure that no DTC is displayed with CONSULT-II or GST.

6. CHECK FOR EVAP LEAK
With CONSULT-II
1. Turn ignition switch ON.
2. Select “EVAP SYSTEM CLOSE” of “WORK SUPPORT” mode with CONSULT-II.
3. Touch “START” and apply pressure into the EVAP line until the pressure indicator reaches the middle of the bar graph.
CAUTION:

Never use compressed air or a high pressure pump.

Do not exceed 4.12 kPa (0.042 kg/cm2 , 0.6 psi) of pres-
sure in the system.

Crankshaft key should line up with the left bank cylinder cen-
ter line as shown in the figure.
3. Install cylinder head follow the steps below to tighten cylinder head bolts in numerical order as shown in the figure with cylin-
der head bolt wrench (commercial service tool).
CAUTION:
If cylinder head bolts are re-used, check their outer diame-
ters before installation. Refer to EM-234, "
Cylinder Head
Bolts Outer Diameter" .
a. Apply new engine oil to threads and seating surface of cylinder head bolts.
b. Tighten all cylinder head bolts.
c. Completely loosen all cylinder head bolts. CAUTION:
In step “c”, loosen cylinder head bolts in reverse order of that indicated in the figure.
d. Tighten all cylinder head bolts.
e. Turn all cylinder head bolts 60 degrees clockwise. (Angle tight- ening)
CAUTION:
Check the tightening angle by using angle wrench (SST).
Avoid judgment by visual inspection without SST.

Check tightening angle indicated on angle wrench indicator
plate.
f. Turn all cylinder head bolts 60 degrees clockwise again. (Angle tightening)
4. Install in the reverse order of removal.
