1. Remove the steering column covers (see page
17-9).
2. Disconnect the cable reel 20P connector (A) from the dashboard wire harness.
3. Using a jumper wire, connect dashboard wire harness 20P connector terminal No. 10 to body
ground. The horn should sound.
 If the horn sounds, go to step 4.
 If the horn does not sound, check these items: – No. 12 (15 A) fuse in the under-hood fuse/relay box.
– MICU.
– Horn.
– Anopeninthewire. 4. Reconnect the cable reel 20P connector (A) to the
dashboard wire harness.
5. Remove the driver’s airbag assembly (see page 24-188), and disconnect the horn switch 1P positive
terminal (B) from the cable reel (C).
6. Using a jumper wire, connect the 1P connector to body ground.
 If the horn sounds, replace the driver’s airbag assembly.
 If the horn does not sound, check these items: – Cable reel.
– Anopeninthewire.
