Control
1. Remove the lower instrument panel.
2. Disconnect the ignition switch connector.
Models from 1984 to 1987.
3. Turn the key to position 1 and check the conductivity between the ACC contacts (white and red wire) and VAT (white wire) on the lock connector. There should be conductivity.
4. Turn the key to position II. Continuity between contacts ACC and BAT should be maintained. Check the continuity between contacts IG1 (black and yellow wire) and IG2 (black and yellow wire), then between contacts IG1 (black and yellow wire) and VAT (white wire). In all cases, conductivity must be present.
5. Turn the key to position III. Continuity between contacts IG1 and IG2 should be maintained. Then check the continuity between contacts IG1 (black and yellow wire) and 5T (black and white wire): it must be.
Models since 1988
Note: The lock contacts are located on the fuse box and main wiring harness.
6. Turn the key to position I. Check the conductivity between the ACC contacts (white-red wire of 4-pin connector) and VAT-8 (black and white wire of 5-pin connector): it must be.
7. Turn the key to position II and check the continuity in the following sequence
- a) ACC and IG2-B terminals (white and blue wire of 5-pin connector) — there must be conductivity.
- b) terminals IG2-B and BAT-B should have conductivity.
- c) terminals BA-A (white wire of 5-pin connector) and IG1 (black and yellow wire of 4-pin connector) — there must be conductivity.
- d) terminals IG1 and IG2-A (yellow wire of 4-pin connector) - there must be conductivity.
8. Turn to position III and check the conductivity in the following sequence
- a) terminals BAT-A and IG1 - there should be conductivity.
- b) terminals IG1 and ST (black and white wire of 4-pin connector) — there must be conductivity.
9. Connect the connectors and install the bottom panel
Replacement
Ignition switch
10. Disconnect the cable from the negative battery terminal.
11. Remove the steering column cover, see section 6 and the lower instrument panel.
12. Ignition key in position 0.
13. Disconnect the ignition switch connectors, unscrew the two mounting screws and remove the switch.
Fig. 7.13 Fastening the ignition switch
14. Installation is performed in the reverse order of removal. Align the steering drive with the ignition switch.
Steering wheel lock (models 1984-1987.)
Note: On these models the steering lock is integral with the steering column.
15. Remove the steering column cover (see section 6).
16. Disconnect the ignition switch connectors.
17. Punch and drill out the heads of the shear-off bolts using a 9.5 mm drill bit.
18. Remove the lock from the column.
19. Install the new lock and install new mounting bolts.
Steering wheel lock (models since 1988)
Note: On 1990 CIVIC and Shuttle models, the steering lock is the same as on 1984-1987 models (see above).
20. Remove the steering wheel (see Chapter 10) and steering column cover (see section 6).
21. Turn the ignition key to position 1.
22. Press the pin located at the top of the lock body and pull out the lock.
23. To install the lock, turn the key to position 0 and put the lock on.
24. Turn the key almost to position 1 and set the lock so that the pin enters the housing.
25. Turn the key to position I. Press the finger and insert it until it clicks.
