Go to Step 2

Go to Step 3

1. Inspect for a short circuit and repair it, if necessary.
2. Replace the fuse.

Is the repair complete?

1. Turn the ignition ON.
2. Measure the voltage at fuse EF20 and EF21.

Does the battery voltage available at these fuses measure within the specified range?

11-14 V

Go to Step 4

Go to Step 7

1. Turn the hazard lamp switch ON.
2. Remove each of the inoperative lamps from its socket.
3. Test each lamp socket positive terminal with a voltmeter.

Does the battery voltage pulsing at the turn signal, hazard lamp socket positive terminal measure within the specified range?

11-14 V

Go to Step 5

Go to Step 9

At each bulb socket, use an ohmmeter to measure the ground circuit.

Is the resistance equal to the specified value?

0 Ω

Go to Step 6

Go to Step 8

Replace any faulty turn signal/hazard bulbs.

1. Disconnect the hazard switch connector.
2. Turn the ignition ON.
3. Measure for voltage at terminal 8.

Does the battery voltage available at terminal 8 measure within the specified range?

11-14 V

Go to Step 10

Go to Step 12

1. Remove the hazard switch.
2. Turn the hazard switch to the OFF position.
3. Inspect for continuity between terminals 7 and 8.
4. Turn the hazard switch ON.
5. Inspect for continuity between terminals 7 and 8.

Do both tests show the specified value?

0 Ω

System OK

Go to Step 11

Replace the faulty hazard switch.
