Note: For a description of the removal/installation of the steering column switches, refer to Section 9, and a spiral spring combined with a return ring - in Section 14; the steering column electronics control unit for models from 06.2010 is integrated with a coil spring.
1. The location of the electrical parts of the steering column is indicated on the resist. illustrations. The following describes the removal / installation of steering column parts only for models up to 05.2010.
17.1а Arrangement of electrical parts of the steering column until 05.2010
1 Left stalk
2 Support for steering column switches
3 Right steering column switch
4 Screw, 0.4 Nm
5 block "J527" steering column electronics control
6 Coil spring "F350"
17.1b Location of electrical parts of the steering column from 06.2010
1 coil spring "F350" with block "J527" steering column electronics control
2 Assembling the steering column switches
3 Assembly support 2
4 Shear bolts, approx. 15 Nm
5 Steering column lock housing
6 Ignition switch
17.1c Location of electrical parts of the steering column from 06.2010 (models with electronic steering column lock)
1-4 See figure captions 17.1b
5 Lock with control unit"J764" steering column lock
6 Switch "Start-stop"
Steering column electronics control unit
2. Remove the steering wheel and steering column trim covers (see chapter 10).
3. Remove the screw (1 per resist. illustrations), insert a drill with a diameter of 2.5 mm (2) into the hole (arrow 1) and unhook the latch in the direction of the arrow (2).
17.3 Releasing the far latch
4. Press the latch on the side of the connector in the direction of the arrow (see resist. illustration), to unhook it, and then carefully remove the control unit from the switches straight down, without skew.
17.4 Releasing the front latch
5. Disconnect the connector (1 per resist. illustrations), pull out the lock (3) from the connector (2), push the latch (arrow B) and disconnect the connector.
17.5 Unit wiring connectors "J527"
6. Installation is carried out in the reverse order. After installing a new unit, it must be programmed.
Support for steering column switches
Note: In the course of work, you will have to drill out the steering column lock bolts, so you must first remove the adjacent parts so that metal particles of the bolts do not get on them.
7. Remove the steering column electronics control unit (see subsection above).
8. Remove the coil spring (see Section 14).
9. Remove both steering column switches (see Section 9).
10. Disconnect the immobilizer sensing coil connector (arrow on resist illustrations), drill out the bolts (1) steering column lock with cylinder and ignition switch (3) and move the support (2) together with the steering column lock from the steering column.
17.10 Bolts (1) steering column lock
11. Press the latches (arrows on resist. illustrations) and remove the lock case (2) steering column with support (1).
12. Installation is carried out in the reverse order. Use new shear bolts.
