SYSTEM DESCRIPTION 

ELECTRONIC CONTROL SYSTEM 

The functions of the fuel and emission control systems are managed by the engine control module (ECM) on 
vehicles with manual transmissions or the powertrain control module (PCM) on vehicles with automatic 
transmissions. 

Self-diagnosis 

The ECM/PCM detects a failure of a signal from a sensor or another control unit and stores a Temporary DTC 
or a DTC. Depending on the failure, a DTC is stored in either the first or the second drive cycle. When a DTC is 
stored, the ECM/PCM turns on the malfunction indicator lamp (MIL) by sending a command to the gauge 
control module. 

Engine stalls (MIL 
works OK, no DTCs set)

2. Check the fuel pressure (see FUEL PRESSURE 

TEST ).  

3. Check the idle speed (see IDLE SPEED 

INSPECTION ).  

4. Troubleshoot the brake pedal position switch 

signal circuit (see BRAKE PEDAL POSITION 
SWITCH SIGNAL CIRCUIT 
TROUBLESHOOTING
 ).  

Intake air leaks  

Faulty harness 
and sensor 
connections  

Difficult to refuel (MIL 
works OK, no DTCs set)

1. Check the fuel vent tube between the EVAP 

canister and the fuel tank.  

2. Check the fuel tank vapor recirculation tube 

between the fuel pipe and the fuel tank.  

3. Replace the fuel tank unit (see FUEL TANK 

UNIT REMOVAL/INSTALLATION ).  

4. Replace the fuel tank (see FUEL TANK 

REPLACEMENT ).  

Malfunctioning gas 
station filling nozzle.

Fuel overflows during 
refueling (No DTCs set)

1. Replace the fuel tank unit (see FUEL TANK 

UNIT REMOVAL/INSTALLATION ).  

2. Replace the fuel tank (see FUEL TANK 

REPLACEMENT ).  

Malfunctioning gas 
station filling nozzle.

HDS does not 
communicate with the 
ECM/PCM or the 
vehicle

Troubleshoot the DLC circuit (see DLC CIRCUIT 
TROUBLESHOOTING
 ).

 

Fuel cap warning 
message comes on and 
stays on (MIL works 
OK, no DTCs set)

Troubleshoot the fuel cap warning message system (see 
FUEL CAP WARNING MESSAGE SYSTEM 
TROUBLESHOOTING
 ).

One Drive Cycle Detection Method 

When an abnormality occurs in the signal from a sensor or another control unit, the ECM/PCM stores a 
DTC for the failure and turns on the MIL immediately. 

Two Drive Cycle Detection Method 

When an abnormality occurs in the signal from a sensor or another control unit in the first drive cycle, the 
ECM/PCM stores a Temporary DTC for the failure. The MIL does not come on at this time. If the failure 
continues in the second drive cycle, the ECM/PCM stores a DTC in erasable memory and turns on the 
MIL. 

Fail-safe Function 

When an abnormality occurs in the signal from a sensor or another control unit, the ECM/PCM ignores that 
signal and substitutes a pre-programmed value that allows the engine to continue running. This causes a DTC to 
be stored and the MIL to come on. 

MIL Bulb Check and Readiness Code Condition 

When the ignition switch is turned ON (II), the ECM/PCM supplies ground to the MIL circuit for about 15 to 
20 seconds to check the bulb condition. If any readiness codes are not set to complete, the MIL flashes five 
times. If all readiness codes are set to complete, the MIL goes off. 

Self Shut Down (SSD) Mode 

After the ignition switch is turned OFF, the ECM/PCM stays on (up to 25 minutes). If the ECM/PCM connector 
is disconnected during this time, the ECM/PCM may be damaged. To cancel this mode, disconnect the negative 
cable from the battery or jump the SCS line with the HDS after the ignition switch is turned OFF.
