Front Fog Lamps Inoperative 1.6L and 1.8L
Diagnostic Aids
The front fog lamps will not operate unless the illumination lamps or daytime running lamps are ON. If the illumination lamps or daytime running lamps are not operating, repair that problem before attempting to diagnose the fog lamps.

1 | Inspect fuse Ef24. Is fuse Ef24 open? | -- | Go to Step 2 | Go to Step 3 |
2 |
Did you complete the action? | -- | System OK | -- |
3 | Use a voltmeter to inspect fuse Ef24. Does the battery voltage available at fuse Ef24 measure within the specified range? | 11-14 V | Go to Step 5 | Go to Step 4 |
4 | Repair the open circuit from the battery to fuse Ef24. Did you complete the repair? | -- | System OK | -- |
5 | Remove the fog lamp relay and temporarily substitute a known good relay, such as the headlamp relay. Do not substitute the illumination lamp relay. Do the fog lamps work with the substituted relay? | -- | Go to Step 6 | Go to Step 7 |

Did you complete the replacement? | -- | System OK | -- |
7 |
Does the voltage available at the fog lamp relay socket measure within the specified range? | 11-14 V | Go to Step 9 | Go to Step 8 |
8 | Repair the open circuit between fuse Ef24 and the fog lamp relay. Did you complete the repair? | -- | System OK | -- |
9 | At the fog lamp relay socket, use an ohmmeter to verify that the connector for relay terminal 85 is connected to ground. Is the resistance equal to the specified value? | 0 ohms | Go to Step 11 | Go to Step 10 |
10 | Repair the ground circuit for the fog lamp relay. Did you complete the repair? | -- | System OK | -- |
11 |
Does the battery voltage available at terminal 2 of the fog lamp connector measure within the specified range? | 11-14 V | Go to Step 13 | Go to Step 12 |
12 | Repair the open circuit between the fog lamp relay terminal 87 and the fog lamps. Did you complete the repair? | -- | System OK | -- |
13 | Use an ohmmeter, or test lamp, to check the ground at terminal 1 of the fog lamp connector. Is the resistance equal to the specified value? | 0 ohms | Go to Step 15 | Go to Step 14 |
14 | Repair the fog lamp ground circuit. Did you complete the repair? | -- | System OK | -- |
15 | Replace the faulty fog lamp bulbs. Did you complete the replacement? | -- | System OK | -- |
