Electronic stability control system on Lancer X

List of components for installation of electronic stability control system on Mitsubishi Lancer X

1. ABS/ASC unit - 4670A719.

Connection of ASC OFF button on Mitsubishi Lancer X

There are 4 wires for the connection on the connector of electronic stability control system. The wires of 2,3 and 4 buttons of electronic stability control system are necessary to be connected to the same wires by the colors in the manual headlamp levelling device connector.

Connect 2 pin with black wire to the 5 pin of manual headlamp levelling device connector.

It is necessary to connect 1 pin to the white with red stripe wire, that begins with C 313 pin 15 connector of ETACS unit.

 That is why, using a multimeter, I found the necessary wire in this connector, if I'm not mistaken, this is the c-28 connector, we connect to pin 4 using a compression terminal or a mating pin to a white with a red stripe wire.

The wiring for button of electronic stability control system has restored.

Installation of G-sensor on Mitsubishi Lancer X

For its installation, it is necessary to disassemble the dashboard lower part, move the central tunnel and remove the lower side panels from the driver's and passenger's side.

You will have the thread for the bracket installation from the factory, that is why fasten the g-sensor to the bracket, and screw the bracket to the vehicle body. The oxygen sensor will interfere with you, unlatch it from the body, screw the bracket, and fasten the sensor itself to the g-sensor bracket.

4 wires of 2 meters from g-sensor, blue and orange wires are the CAN bus bar, they must be obligatory spliced between each other throughout the length.

1 wire of 2,5 meters for the hydraulic unit supply from ETACS unit. On before restyling, one can take the supply from the c-128 connector pin 2. And on restyling, the c-128 connector is absent, that is why connect c-315 connector pin 4 directly to the ETACS unit.

I will lay these 5 Wires to the hydraulic unit through protective cover in the glove box. I remove it and make a hole of 5-6mm and then insert the wires. 

After that, I isolate the wires throughout the length and lay them to the hydraulic unit.

I will lead these wires in the interior from the bottom up, in order to fully eliminate the water running-off in the interior from the underhood space. 

Installation of steering angle sensor on Mitsubishi Lancer X

If you have before restyling Lancer X before 2011 year of manufacture, then the connector for steering angle sensor connection will be from the factory. And on restyled Lancer X, wiring and connector are absent, it is necessary to restore them.

Be sure to make a mark on the steering wheel and steering wheel shaft to put the steering wheel back in the correct position.

Carefully screw the steering position sensor onto it from the back side. The main thing is not to change the zero position. We lay the wires in a special groove.

- With two black wires we connect to the same black wires at the left turn signal and light switch using compression terminals.  

- The remaining 2 wires, brown and green, are pulled by the dashboard to two connectors. There will be a connector behind the dashboard, it is necessary to connect our remaining wires into it: brown above black, green above orange. 

Installation of ABS/ASC 4670A719 unit on Mitsubishi Lancer X

Remove two-row connector, for that purpose transmit simultaneously the orange fixator in the opening position and simultaneously remove it.

Next, it is necessary to unscrew 6 hydraulic tubes. Those, that are thicker, are input and unscrew with 12 mm wrench. Those, that are thinner, are output and unscrew with 10 mm wrench.

I used split keys. The input tubes were unscrewed with 12 mm wrench without any problems, but I could not unscrew the output tubes, given keys began to grind the edges.

For this reason, I used upgraded wrenches with draw bolt. With the help of these wrenches, I unscrewed everything without any problems, keeping all edges on nuts.

Unscrew the bracket, it is fastened with 3 nuts. Remove the old ABS unit and install the new one.

Screw, firstly, 2 input tubes to the new ABS/ASC 4670A719 unit and bleed the brakes a little in order to fill the unit with brake fluid. And only after that screw the remain 4 output tubes.

Repinning of three-row connector for ASC on Mitsubishi Lancer X

Disassemble connectors, remove upper cover, unlatch white pins fixator, the pins are held by small clamps, that are necessary to bend with a needle or thin driver, after that pins are removed without any problems.

Transfer pins to three-row connector in accordance with the following scheme:

Next, add 4 wires from g-sensor to the three-row connector, as one has g-sensor of new type, then the connector is also of new type with 4 pins. I make the random numeration, the orienting point is the latch from the right.

And connect the last wire to the three-row connector, the supply from ETACS unit from the c-315 connector pin 4 - connect to the pin 2 of three-row connector. And only now, one can connect this wire to the c-315 connector pin 4 of ETACS unit.

It is also obligatory to check the level of brake fluid in the tank, according to reducing - add the new.

Activating of electronic stability control system ACS (ESP) on Mitsubishi Lancer X

Next ride on the even surface and calibrate in the MMCodingWriter program the g-sensor first, and then the steering angle sensor. That is all, the activating is completed.
