Headlight System - Lancer: Overview Mitsubishi Lancer X рестайлинг

Scheme 1

1. As for headlight assembly, a type with halogen bulbs for the high-beam and low-beam and a type with a discharge bulb for both high-beam and low-beam are established.
2. The halogen bulb type headlight assembly employs the four-light type integrated with the headlight (low-beam), headlight (high-beam), front turn-signal light, and position light. The dimmed headlight (low-beam) is also used as a daytime running light.
3. For the discharge bulb type headlight assembly, the headlight assembly with two headlights has been adopted which incorporates the projector type headlight (low-beam/high-beam), daytime running light, front turn-signal light, and position light. Also, the headlight manual leveling system has been adopted. The switching of headlight (low-beam/high-beam) is performed by the driving of light-shield in the projector unit using the signal from lighting switch.

CHECK OF CONTROLLER OPERATION

If any of the abnormalities below are found, replace the controller.

Note. Ensure that the headlight control system and its circuit (power supply control at engine start and during steady illumination, high-voltage generating circuit, etc.) are working normally. Then, check whether any internal breakage has occurred in the controller. However, some internal breakage may not be found.

CONTROLLER REPLACEMENT

TECHNICAL DESCRIPTION (COMMENT)

The ETACS-ECU sets DTC B16A2 under the following conditions.

1. If there is a malfunction to the left turn-signal light bulb, the blown left bulb counter counts once when the illumination of hazard or turn-signal light (left side) is attempted.
2. After the bulb counter reaches "3," DTC B16A2 is set.

When the short circuit is detected three times consecutively, the ETACS-ECU sets the DTC B16A3.

The ETACS-ECU sets DTC B16A4 under the following conditions.

1. If there is a malfunction to the right turn-signal light bulb, the blown right bulb counter counts once when the illumination of hazard or turn-signal light (right side) is attempted.
2. If the blown right bulb counter reaches "3," the DTC B16A4 is set.

When the short circuit is detected three times consecutively, the ETACS-ECU sets the DTC B16A5.

The lighting control sensor may have been installed with the wrong procedure.

1. Incorrect installation procedure: Connect the connector before mounting the lighting control sensor onto the optical coupler of the windshield.
2. Correct installation procedure: Mount the lighting control sensor onto the optical coupler of the windshield. Wipe the windshield surface thoroughly, and check that the surface is dry. Then, connect the connector.

Malfunction of the lighting control sensor

If none of headlights (low-beam) illuminates, the headlight switch input circuit, headlight relay (LOW), or ETACS-ECU may have a problem.

If none of headlights (high-beam) illuminates, the headlight switch input circuit, headlight relay (HIGH), or ETACS-ECU may have a problem.

If the headlights illuminate only at low-beam regardless of the lighting switch position, the headlight fail-safe function may be active.

If none of headlights (low-beam and high-beam) illuminates, the passing switch input circuit or ETACS-ECU may have a problem.

When one of the headlights does not illuminate, the wiring harness, connector(s), or the bulb may have a problem, or the fuse may be burned out.

If the high-beam indicator does not illuminate normally, the harness in the CAN bus lines, connector(s), ETACS-ECU, or combination meter may have a problem.

OPERATION

The ETACS-ECU operates this function in accordance with the input signals from column switch (lighting switch), ignition switch (IG1), and front door switch (LH).

If the headlight automatic shutdown function does not work normally, the above described input circuits or ETACS-ECU may have a problem. Also, it may be possible that the headlight automatic shutdown function is set to "Disable" through configuration function.

If the daytime running light function does not work, connector(s), wiring harness in the CAN bus lines, the engine control module, the combination meter, the ETACS-ECU or the input signal circuit may be defective.

If one of the position light, the taillight, the rear side marker light or the license plate light does not illuminate normally, the harness, connector(s), or bulb(s) may have a problem, or the fuse may be burned out.

The ETACS-ECU operates this function in accordance with the input signals from driving distance, lighting control sensor, and column switch (auto light switch). Also, when the column switch (lighting switch) is in the "AUTO" position, and when an abnormality is present to the auto light circuit, the fail-safe function is activated and the low beam is turned ON at all times regardless of the brightness around the vehicle.

If the auto light function does not work normally, the above input signal circuit(s) or the ETACS-ECU may have a problem.

If none of turn-signal lights illuminates, the ignition switch (IG1), the turn-signal light switch input circuit or the ETACS-ECU may have a problem.

If the comfort flashing function does not work normally, the turn-signal light switch input circuit(s) and ETACS-ECU may have a problem.

If the turn-signal light indicator does not illuminate normally, the harness in the CAN bus lines, connector(s), ETACS-ECU, or combination meter may have a problem.

When the welcome light function does not operate normally, the keyless entry system or the ETACS-ECU may have a problem. Or, the welcome light function may have been set to disabled using the customization function.

When the coming home light function does not operate normally, the keyless entry system or the ETACS-ECU may have a problem. Or, the coming home light function may have been set to disabled using the customization function.
