Circuit/System Verification

1. Ignition ON, observe the function of the E2LF side marker lamp-left front, E5E tail lamp-left rear and the E4J park lamp-left front while

commanding the Left Park Lamps ON and OFF with a scan tool. The E2LF side marker lamp-left front, E5E tail lamp-left rear and the E4J

park lamp-left front should turn ON and OFF while changing between the commanded states

瀚慖f the E2LF side marker lamp-left front, E5E tail lamp-left rear and the E4J park lamp-left front are always ON or always OFF, refer to

Left Side Marker/Tail Lamps Malfunction.

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:
