Daytime Running Lamps (DRL) Inoperative 2.0 Liter
Diagnostic Aids
The daytime running lamp (DRL) system will not operate if the parking brake is applied. The system is designed to operate only when the engine is running and the parking brake released. If the parking brake circuit is shorted to ground or the switch stays closed when the engine is running, the DRL system will not operate.
Step | Action | Values | Yes | No |
|---|---|---|---|---|
1 | Turn the headlamps ON. Do the headlamps, parking lamps, tail lamps, and instrument lamps work? | -- | Go to Step 3 | Go to Step 2 |
2 | Repair the regular headlamp system before completing this diagnostic table. Does the DRL system work after the headlamps, exterior lamps, and instrument lamp systems have been repaired? | -- | System OK | Go to Step 3 |
3 | Inspect fuses EF26 and EF21. Is fuse EF26 or EF21 open? | -- | Go to Step 4 | Go to Step 5 |
4 |
Is the repair complete? | -- | System OK | -- |
5 |
Does the voltage measure within the specified range? | 11-14 V | Go to Step 7 | Go to Step 6 |
6 | Repair the power supply circuit for fuse EF26 and/or EF21. Is the repair complete? | -- | System OK | -- |
7 |
Is the voltage within the specified range? | 11-14 V | Go to Step 9 | Go to Step 8 |
8 | Repair the open circuit between fuse EF21 and terminal 2 of the DRL module connector. Is the repair complete? | -- | System OK | -- |
9 | With the electrical connector still disconnected from the DRL module, measure the voltage at terminal 8 of the DRL module. Is the voltage within the specified range? | 11-14 V | Go to Step 11 | Go to Step 10 |
10 | Repair the open circuit between fuse EF26 and terminal 8 of the DRL module connector. Is the repair complete? | -- | System OK | -- |
11 | With the DRL module still disconnected, use an ohmmeter to measure the resistance between ground and terminal 4 of the DRL module connector. Is the resistance equal to the specified value? | 0 ohms | Go to Step 13 | Go to Step 12 |
12 | Repair the circuit between ground and terminal 4 of the DRL module connector. Is the repair complete? | -- | System OK | -- |
13 |
Is the parking brake indicator lamp ON? | -- | Go to Step 14 | Go to Step 17 |
14 | Disconnect the electrical connector to the parking brake lever switch. Is the parking brake indicator lamp still ON? | -- | Go to Step 15 | Go to Step 16 |
15 | Repair the wire short to ground in the parking brake circuit. Is the repair complete? | -- | System OK | -- |
16 | Replace the parking brake lever switch. Is the repair complete? | -- | System OK | -- |
17 | Replace the DRL module. Is the repair complete? | -- | System OK | -- |
