Inspection
Measure the horn relay resistance between terminals (indicated in table below) when connecting the terminal No. 4 to battery positive terminal and terminal No. 3 to battery ground cable.
Scheme 1
| Current | Terminal No. | Standard |
|---|---|---|
| Flow | 1 and 2 | Less than 1 O |
| No Flow | More than 1 MO |
HORN RELAY RESISTANCE SPECIFICATIONS
With 12 V direct current supplied between horn terminal and case ground, check that the horn sounds properly.
Scheme 2
Measure the resistance between horn switch terminal and airbag module bracket.
Scheme 3
- Horn switch terminal
- Airbag module bracket
| Switch position | Terminal No. | Resistance |
|---|---|---|
| When airbag module bracket is pushed. | Horn switch terminal and Airbag module bracket | Less than 1 O |
| When airbag module bracket is not pushed. | More than 1 M O |
