Ignition lock wiring diagram: 1 - switch contact group (castle) ignition (0 - "turned off"; I - "included"; II - "starter"); 2 - backlight; 3 - microswitch; 4 - wiring harness block
Comment. In the absence of special bolts, you can fix the new lock with M6 threaded bolts 20 mm long, although the anti-theft security of the car will be significantly reduced.
Removing
1. Remove the steering column trim (see "Decorative overlays of a steering column - removal and installation").
2. Disconnect the ignition switch wiring harness blocks (see above).
3. Having rested the chisel blade on the edge of the head of one of the bolts, with light blows of the hammer on the chisel, loosen the bolt tightening.
Comment. The chisel should not cut the head of the bolt, but only turn the bolt counterclockwise to loosen it.
4. Using pliers with narrow jaws, we unscrew the bolt.
5. Similarly, unscrew the three remaining ignition bolts.
Comment. When unscrewing the last bolt, hold the ignition switch.
6. Remove the lock bracket...
...and the ignition lock itself from the steering column.
Installation
1. Before installing the ignition switch, insert the key into it and turn it to position I ("included"), so that the latch of the steering lock mechanism is pushed into the lock body.
2. We install the ignition switch with the mounting bracket on the steering column and hand-tighten the new mounting bolts.
3. Having removed the key from the ignition lock, we check the operation of the steering shaft lock mechanism. If the steering shaft does not lock after a full turn of the steering wheel, adjust the position of the ignition switch on the steering column so that the latch of the lock can fit into the groove on the steering shaft.
4. After making sure that the locking mechanism works, use the ring wrench by 10 mm evenly (crosswise, half turn) tighten the bolts until their heads come off.
5. Further work is carried out in the reverse order of removal.
