DTC Logic
DTC DETECTION LOGIC
With the Air/Fuel Mixture Ratio Self-Learning Control, the actual mixture ratio can be brought closely to the theoretical mixture ratio based on the mixture ratio feedback signal from A/F sensor 1. The ECM calculates the necessary compensation to correct the offset between the actual and the theoretical ratios.
In case the amount of the compensation value is extremely large (the actual mixture ratio is too lean), the ECM judges the condition as the fuel injection system malfunction and illuminates the MIL (2 trip detection logic).
DTC CONFIRMATION PROCEDURE
1.PRECONDITIONING
If DTC Confirmation Procedure has been previously conducted, always perform the following before conducting the next test.
2.PERFORM DTC CONFIRMATION PROCEDURE-I
3.RESTART ENGINE
If it is difficult to start engine, the fuel injection system has a malfunction, too.
Crank engine while depressing accelerator pedal.
NOTE:
4.PERFORM DTC CONFIRMATION PROCEDURE-II
5.PERFORM DTC CONFIRMATION PROCEDURE-III
Hold the accelerator pedal as steady as possible. CAUTION: Always drive vehicle at a safe speed.
Diagnosis Procedure
1.CHECK EXHAUST GAS LEAKAGE
2.CHECK FOR INTAKE AIR LEAKAGE
3.CHECK A/F SENSOR 1 INPUT SIGNAL CIRCUIT
4.CHECK FUEL PRESSURE
At idling: Approximately 350 kPa (3.57 kg/cm2, 51 psi)
5. DETECT MALFUNCTIONING PART
Check fuel hoses and fuel tubes for clogging.
6.CHECK MASS AIR FLOW SENSOR
For specification, refer to EC-596, "Mass Air Flow Sensor".
With GST
7.CHECK FUNCTION OF FUEL INJECTOR
With CONSULT
With GST
8.CHECK FUEL INJECTOR
Keep fuel hose and all fuel injectors connected to fuel tube.
For DTC P0174, reconnect fuel injector harness connectors on bank 2.
For DTC P0171, check that fuel sprays out from fuel injectors on bank 1.
For DTC P0174, check that fuel sprays out from fuel injectors on bank 2.
Fuel should be sprayed evenly for each fuel injector.
9.CHECK INTERMITTENT INCIDENT

Rear Door Glass Regulator
REMOVAL
Remove the rear door finisher. Refer to INT-21, "Removal and
Installation".
Position aside the vapor barrier.
Temporarily reconnect the power window switch and raise/lower
the door window until the glass bolts can be seen.
