2. Ignition ON, observe the function of the E2RF side marker lamp-right front, E5F tail lamp-right rear and the E4K park lamp-right front while

commanding the Right Park Lamps ON and OFF with a scan tool. The E2RF side marker lamp-right front, E5F tail lamp-right rear and the

E4K park lamp-right front should turn ON and OFF while changing between the commanded states.

瀚慖f the E2RF side marker lamp-right front, E5F tail lamp-right rear and the E4K park lamp-right front are always ON or always OFF, refer

to Right Side Marker/Tail Lamps Malfunction.

Circuit/System Testing

Left Side Marker/Tail Lamps Malfunction

1. Disconnect the X1 harness connector at the E5E tail lamp-left.

2. Test for less than 30 ohm between the ground circuit terminal C and ground.

瀚慖f greater than the specified range, test the ground circuit for an open/high resistance.

3. Disconnect the appropriate inline harness connector listed below:

* X111 inline harness connector (With TT6/TT7/TT8)

* X115 inline harness connector (Without TT6/TT7/TT8)

4. Test for less than 30 ohm between the ground circuit terminal listed below and ground:

* Ground circuit terminal A

* Ground circuit terminal E

瀚慖f greater than the specified range, test the ground circuit for an open/high resistance.

5. Connect a test lamp between the control circuit terminal listed below and ground.

* E2LF side marker lamp-left front control circuit terminal K

* E4J park lamp-left front control circuit terminal B

* E5E tail lamp-left control circuit terminal B

6. Ignition ON, command the Left Park Lamps ON and OFF with a scan tool. The test lamp should turn ON and OFF when changing between

the commanded states.

瀚慖f the test lamp is always ON, test the control circuit for a short to voltage. If the circuit tests normal, replace the K9 BCM.

瀚慖f the test lamp is always OFF, test the control circuit for a short to ground or an open/high resistance. If the circuits test normal, replace

the K9 BCM.

7. If all the circuits test normal, replace the appropriate left marker lamp.

Right Side Marker/Tail Lamps Malfunction

1. Disconnect the X1 harness connector at the E5F tail lamp-right.

2. Test for less than 30 ohm between the ground circuit terminal C and ground.

瀚慖f greater than the specified range, test the ground circuit for an open/high resistance.

3. Ignition OFF, disconnect the appropriate inline harness connector listed below:

* X112 inline harness connector (With TT6/TT7/TT8)

* X116 inline harness connector (Without TT6/TT7/TT8)

4. Test for less than 30 ohm between the ground circuit terminal listed below and ground:

* Ground circuit terminal A

* Ground circuit terminal E

瀚慖f greater than the specified range, test the ground circuit for an open/high resistance.

5. Connect a test lamp between the control circuit terminal listed below and ground.

* E2RF side marker lamp-right front control circuit terminal K

* E4K park lamp-right front control circuit terminal B

* E5F tail lamp-right control circuit terminal A

6. Ignition ON, command the Right Park Lamps ON and OFF with a scan tool. The test lamp should turn ON and OFF when changing between
