Simplified Wiring System (Sws) - Except Evolution: Removal & Installation Mitsubishi Lancer IX

Step 13: Replace The ECU

1. Replace the column switch.
2. The system should communicate with the column switch (column-ECU) normally.

Can the system communicate with the column switch (column-ECU)?

1. YES No action is necessary and testing is complete.
2. NO Replace the ETACS-ECU. The system should communicate with the column switch (column-ECU) normally.

Step 10: Replace The ECU

1. Replace the front-ECU.
2. The system should communicate with the front-ECU normally.

Can the system communicate with the front-ECU?

1. YES No action is necessary and testing is complete.
2. NO Replace the ETACS-ECU. The system should communicate with the front-ECU normally.

Step 12: Replace The Sunroof Motor Assembly

1. Replace the sunroof motor assembly.
2. The system should communicate with the sunroof motor assembly normally.

Can the system communicate with the sunroof motor assembly?

1. YES No action is necessary and testing is complete.
2. NO Replace the ETACS-ECU. The system should communicate with the sunroof motor assembly (sunroof-ECU) normally.

Step 2: Replace The ECU

1. Replace the column switch (turn-signal light and lighting switch).
2. If the functions, which are described in «Circuit Operation»(ref-169966-S05768742592005010500000) , work normally, the input signal from the column switch (turn-signal light and lighting switch) should be normal.

Does the column switch (turn-signal light and lighting switch) send normal signal to the ECU?

1. YES No action is necessary and testing is complete.
2. NO Replace the ETACS-ECU. If the functions, which are described in «Circuit Operation»(ref-169966-S05768742592005010500000) , work normally, the input signal from the column switch (turn-signal light and lighting switch) should be normal.

Step 4: Replace The ECU

1. Replace the column switch (turn-signal light and lighting switch).
2. If the equipment, which are described in «Circuit Operation»(ref-169966-S02677930232005010500000) , work normally, the input signal from the column switch (windshield wiper and washer switch) should be normal.

Does the column switch (windshield wiper and washer switch) send a normal signal to the ECU?

1. YES No action is necessary and testing is complete.
2. NO Replace the ETACS-ECU. If the equipment, which are described in «Circuit Operation»(ref-169966-S02677930232005010500000) , work normally, the input signal from the column switch (windshield wiper and washer switch) should be normal.

Step 5: Replace The ECU

1. Replace the ETACS-ECU.
2. If the wiper interval can be adjusted normally, it indicates that the windshield intermittent wiper interval adjusting knob should send a signal to the ECU.

Can input signal be confirmed when the windshield intermittent wiper interval adjusting knob is operated?

1. YES No action is necessary and testing is complete.
2. NO Replace the column switch (windshield wiper and washer switch). If the wiper interval can be adjusted normally, it indicates that the windshield intermittent wiper interval adjusting knob should send a signal to the ECU.

1. Replace the sunroof motor assembly.
2. If the sunroof operates normally, it indicates that a correct signal is sent from the sunroof switch.

Does the ETACS-ECU receive correct signals from the sunroof switch?

1. YES No action is necessary and testing is complete.
2. NO Replace the ETACS-ECU. If the sunroof operates normally, it indicates that a correct signal is sent from the sunroof switch.
