INTERMITTENT PROBLEM PROCEDURE
1. | Clear diagnostic trouble code(DTC).
2. | Inspect connector connection and check terminal for poor connections, loose wires, bent or broken pins and corrosions. Make sure that the connectors are always securely fastened.
3. | Perform a simulation test.(See next page)
4. | Repair or replace the componect that has a problem.
5. | Verify that the problem has disappeared with the road test.
ECM PROBLEM PROCEDURE
1. | Turn ignition switch to OFF.
2. | Disconnect ECM connector, measure the resistance between ground terminal on the ECM side (terminal 1, 2) and chassis ground.
3. | Inspect connector connection and check terminal for poor connections, loose wires, bent or broken pins and corrosion.
4. | If it is abnormal, repair it. If it is normal, the ECM could be faulty.
5. | Temporarily install a good ECM and check for proper operation. If problem disappeared, replace ECM.
SIMULATION TEST
1. | Vibration
A. | Slightly shake the connector and wiring harness up and down and right and left.
B. | Slightly Vibrate sensors or actuators.
2. | Heat
A. | Heat components that likely caused the malfunction with a hair dryer or others.
B. | Do not heat the components to the point where they may be damaged and do not heat the ECM directly.
3. | Water sprinkling
A. | Sprinkle water onto vehicle to simulate a rainy day or a high humidity condition.
B. | In this test, do not sprinkle water directly onto the engine compartment or electronic components.
4. | Electrical loads
A. | Turn on all electrical systems to simulate excessive electrical loads.
MFI SYSTEM INSPECTION
1. | Engine is hard to start or does not start at all.
2. | Unstable idle.
3. | Poor driveability.
• | Before removing or installing any parts, read the diagnostic trouble codes and then disconnect the battery negative (-) terminal.
• | Before disconnecting the cable from the battery terminal, turn the ignition switch to the OFF position. Removal or connection of the battery cable during engine operation or while the ignition switch is ON could cause damage to the ECM.
• | The control harnesses between the ECM and heated oxygen sensor are shielded with the shielded ground wires to the body in order to prevent the influence of ignition noises and radio signals. When the shielded wire is faulty, the control harness must be replaced.
• | When checking the generator for charging ability, do not disconnect the battery '+' terminal to prevent the ECM from being damaged.
• | When charging the battery with the external charger, disconnect the battery terminals from the vehicle to prevent damage to the ECM.

[INSPECTION]
1. | After turning ON the ignition key, ensure that the light illuminates before engine starts and then goes out.
2. | If the light does not illuminate, check for an open circuit in the harness, a blown fuse or a blown bulb.
If a sensor connector is disconnected with the ignition switch turned on, the diagnostic trouble code (DTC) is recorded. In this case, disconnect the battery negative terminal (-) for 15 seconds or more, and the diagnosis memory will be erased.
THE RELATION BETWEEN DTC AND DRIVING PATTERN IN EOBD SYSTEM
1. | When the same malfunction is detected and maintained during two sequential driving cycles, the MIL will automatically illuminate.
2. | The MIL will go off automatically if no fault is detected after 3 sequential driving cycles.
3. | A Diagnostic Trouble Code (DTC) is recorded in ECM memory when a malfunction is detected after two sequential driving cycles.
4. | The MIL will illuminate whenthe malfunction is detected on the second driving cycle. If a misfire is detected, a DTC will be recorded and the MIL will illuminate immediately after a fault is first detected.
5. | A Diagnostic Trouble Code(DTC) will automatically be erased from the ECM memory if the same malfunction is not detected for 40 driving cycles.
• | A "warm-up cycle" means sufficient vehicle operation such that the coolant temperature has risen by at least 40 degrees Fahrenheit from engine starting and reaches a minimum temperature of 160 degress Fahrenheit.
• | A "driving cycle" consists of engine startup, vehicle operation beyond the beginning of closed loop operation.
