MFI SYSTEM INSPECTION

Engine is hard to start or does not start at all.

Unstable idle.

Poor driveability.

note

●

Before removing or installing any part, read the diagnostic trouble codes and then disconnect the battery negative (-) terminal.

●

Before disconnecting the cable from battery terminal, turn the ignition switch to OFF. 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 interference. When the shielded wire is faulty, the control harness must be replaced.

●

When checking the generator for the charging state, do not disconnect the battery '+' terminal to prevent the ECM from damage due to the voltage.

●

When charging the battery with the external charger, disconnect the vehicle side battery terminals to prevent damage to the ECM.

ECM

After turning ON the ignition key, ensure that the light illuminates for about 5 seconds and then goes out.

If the light does not illuminate, check for an open circuit in the harness, a blown fuse or a blown bulb.

SELF-DIAGNOSIS

The ECM monitors the input/output signals (some signals at all times and the others under specified conditions). When the ECM detects an irregularity,it records the diagnostic trouble code, and outputs the signal to the Data Link connector. The diagnosis results can be read with the MIL or HI-SCAN.Diagnostic trouble codes (DTC) will remain in the ECM as long as battery power is maintained. The diagnostic trouble codes will, however, be erased when the battery terminal or the engine control module (ECM) connector is disconnected or by HI-CAN.

note

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

When the same malfunction is detected and maintained during two sequential driving cycles, the MIL will automatically illuminate.

The MIL will go off automatically if no fault is detected after 3 sequential driving cycles.

A Diagnostic Trouble Code(DTC) is recorded in ECM memory when a malfunction is detected after two sequential driving cycles. The MIL will illuminate when the 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.

A diagnostic Trouble Code(DTC) will automatically erase from ECM memory if the same malfunction is not detected for 40 driving cycles.

note

●

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.
