Horn: Testing and Inspection

INSPECTION




1. INSPECT HORN FUSE
a. Check the resistance.
1. Using an ohmmeter, measure the resistance between each terminals.

Standard resistance: Below 1 Ohm

If the result is not as specified, replace the fuse.

2. INSPECT HORN RELAY







a. Check the resistance.
1. Using an ohmmeter, measure the resistance between the terminals.

3. INSPECT HIGH PITCHED HORN ASSEMBLY







a. Check the operation.
1. Apply battery voltage, then check the horn.
If the result is not as specified, replace the horn.

4. INSPECT LOW PITCHED HORN ASSEMBLY







a. Check the operation.
1. Apply battery voltage, then check the horn.
If the result is not as specified, replace the horn.
If all the check results are as specified above and the wire harness is normal, replace the horn button switch (steering wheel pad).
