Do the rear hazard lamps operate normally?

--

Go to Step 20

Go to Step 3

Inspect the STP HAZ fuse #8 for an open.

Is the STP HAZ fuse #8 open?

--

Go to Step 13

Go to Step 4

1. Disconnect the hazard switch jumper harness connector C215.
2. Turn the ignition switch to the on position.
3. Using a test light, test for voltage at the instrument panel harness side of connector C215 terminal B.

Does the test light illuminate?

--

Go to Step 5

Go to Step 12

Connect a fused jumper wire between terminals B and J, of the instrument panel harness connector C215.

With the ignition switch on, do the rear turn signal lamps illuminate?

--

Go to Step 10

Go to Step 6

1. Turn the ignition switch off and remove the fused jumper wire.
2. Disconnect the multifunction switch connector C209.
3. Using a DMM measure the resistance of circuit 27, from the instrument panel harness connector C215 terminal J, to instrument panel harness connector C209 terminal A.

Is the resistance within specified values?

0-2 ohms

Go to Step 7

Go to Step 11

Using a DMM measure the following resistances through the turn signal switch while in the neutral position:

Is the resistance in both measurements within specified values?

0-2 ohms

Go to Step 8

Go to Step 9

Inspect and repair the open or high resistance in circuits 18 or 19, if OK replace the inoperative bulbs.

1. Remove the STP HAZ fuse #8.
2. Connect a DMM from the fuse terminal A, in the instrument panel electrical center to ground.

With the hazard switch off, is resistance less than specified values?

0.5ohms

Go to Step 17

Go to Step 14

1. With the DMM connected as in the previous step.
2. Press the brake pedal.

Is resistance less than specified values?

0.5ohms

Go to Step 15

Go to Step 16

1. Disconnect the multifunction switch connector.
2. With the DMM connected as in the previous step.
3. Depress the brake pedal.

Is resistance less than specified values?

0.5ohms

Go to Step 18

Go to Step 19

Inspect the hazard warning switch for a short to ground, and replace if necessary. Refer to Hazard Warning Switch Replacement .
