Contents:
1.Turn ignition switch OFF and disconnect the negative (-) battery terminal.
2.Remove the fuse box cover.
3.Remove the starter relay (A).

4.Check for continuity between the terminals (30 and 87) using an ohmmeter.
| Terminal | Resistance | Measure |
| 30 - 87 | 1MΩ or higher | If there is continuity between the terminals, replace the relay. |

5.Apply 12V to the terminal 85 and ground to the terminal 86 and then check for continuity between the terminals (30 and 87).
| Terminal | Resistance | Measure |
| 30 - 87 | 1Ω or less | If there is no continuity between the terminals, replace the relay. |

6.Install the starter relay.
7.Install the fuse box cover.
