Go to Diagnostic System Check - Lighting Systems

1. Turn ON the ignition, with the engine OFF.
2. Observe the turn signal lamps and indicators.
3. Turn ON and OFF the right and left turn signal lamps.
4. Turn OFF the ignition.

Do the turn signal lamps and indicators operate properly?

Go to Testing for Intermittent Conditions and Poor Connections in Wiring Systems

Go to Step 3

Are only the turn signal indicators always ON or flashing?

Go to Step 6

Go to Step 4

Test the always ON or flashing turn signal bulb supply voltage circuit for a short to battery positive voltage. Refer to Circuit Testing and Wiring Repairs in Wiring Systems.

Did you find and correct the condition?

Go to Step 16

Go to Step 5

1. Disconnect the turn signal/hazard flasher module.
2. Connect a test lamp between the always ON or flashing turn signal cornering lamp supply voltage circuit of the turn signal/hazard flasher module and ground.
3. Turn OFF the always ON or flashing turn signal.

Does the test lamp illuminate?

Go to Step 7

Go to Step 8

1. Disconnect the component with the always on or flashing turn signal indicator.
2. Connect a test lamp between turn signal lamps supply voltage circuit of the turn signal indicator and the ground circuit of the component with the turn signal indicator.
3. Turn OFF the always ON or flashing turn signal indicator.

Does the test lamp illuminate?
