Low and High Beams Inoperative

Step Action Values Yes No
1 Inspect fuses F6, Ef12, Ef20, Ef27, and Ef15.
Is any fuse open?		 - Go to Step 2  Go to Step 3 
2
  1. Inspect for a short circuit and repair if necessary.
  2. Replace the fuse.
Did you find and correct the condition?		 - System OK -
3
  1. Turn the low-beam headlamps ON.
  2. Measure the voltage at fuses Ef20, Ef27, and Ef15.
Does the voltage at the headlamps measure within the specified range?		 11-14 V Go to Step 4  Go to Step 9 
4
  1. Turn the low-beam headlamps ON.
  2. Measure the voltage at the headlamp connector terminal 5 (terminal 1 if hatchback).
  3. Turn the high-beam headlamps ON.
  4. Measure the voltage at headlamp connector terminal 4 (terminal 2 if hatchback).
Does the battery voltage available at the headlamps measure within the specified value?		 11-14 V Go to Step 6  Go to Step 5 
5 Repair the open circuit between fuses Ef20, Ef27 and Ef15 and the headlamps.
Did you complete the repair?		 - System OK -
6 Use an ohmmeter to check between ground and each headlamp connector terminal 6 (terminal 3 if hatchback).
Is the resistance equal to the specified value?		 0 Ω Go to Step 8  Go to Step 7 
7 Repair the ground circuit.
Did you complete the repair?		 - System OK -
8
  1. Replace the faulty headlamps.
  2. Inspect the charging system to make sure the charging voltage is not excessively high. Repair if necessary.
Did you find and correct the condition?		 - System OK -
9 Temporarily substitute the illumination relay in place of the headlamp relay.
Do the headlamps operate with the substituted relay?		 - Go to Step 10  Go to Step 11 
10 Install the illumination relay in its original position, and install a new headlamp relay.
Did you find and correct the condition?		 - System OK -
11
  1. With the headlamp relay removed, turn the headlamp switch to the low-beam position.
  2. Use an ohmmeter to check the continuity between the connector for relay terminal 85 and ground.
Does the ohmmeter indicate the specified value?		 0 Ω Go to Step 17  Go to Step 12 
12
  1. Reinstall the headlamp relay.
  2. Measure the voltage at the light switch connector terminal 2.
Does the voltage measure within the specified range?		 11-14 V Go to Step 14  Go to Step 13 
13 Repair the open circuit between headlamp relay terminal 85 and the light switch connector terminal 2.
Did you complete the repair?		 - System OK -
14
  1. Disconnect the light switch connector.
  2. Turn the headlamps to the low-beam position.
  3. Use an ohmmeter to check the continuity between terminals 2 and 3 of the light switch.
Does the ohmmeter indicate the specified value?		 0 Ω Go to Step 16  Go to Step 15 
15 Replace the light switch.
Did you complete the replacement?		 - System OK -
16 Repair the open circuit between terminal 3 of light switch connector and ground.
Did you complete the repair?		 - System OK -
17 Measure the voltage at headlamp switch connector terminal 6.
Does the voltage measure within the specified range?		 11-14 V Go to Step 19  Go to Step 18 
18 Repair the open circuit between headlamp switch connector and terminal 87 of the headlamp relay.
Did you complete the repair?		 - System OK -
19
  1. Disconnect headlamp switch connector.
  2. Turn the headlamps to the low-beam position.
  3. Connect an ohmmeter between terminals 5 and 6 of headlamp switch connector. Observe the reading on the ohmmeter.
  4. Turn the headlamps to the high-beam position.
  5. Connect an ohmmeter between terminals 4 (terminal 2 if hatchback) and 6 of the headlamp switch. Observe the reading on the ohmmeter.
Does the ohmmeter show the specified value for both of the tests?		 0 Ω Go to Step 20  Go to Step 15 
20 Repair the open circuit between the headlamp switch and fuses Ef20, Ef27 and Ef15.
Did you complete the repair?		 - System OK -
