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
