Headlight Relay Test
1. Remove the headlight relay from the under-hood
fuse/relay box.
2. Check continuity at the relay terminals.
• There should be continuity between the C and D
terminals.
• There should be continuity between the A and B
terminals when power and ground are connect-
ed to the C and D terminals.
• There should be no continuity between the A and
B terminals when power is disconnected.
Dimmer Relay Test
1. Remove the dimmer relay from the under-hood
fuse/relay box.
2. Check continuity at the relay terminals.
• There should be continuity between the F and E
terminals and between the B and C terminals.
• There should be continuity between the A and C
terminals when power and ground are connect-
ed to the E and F terminals.
• There should be no continuity between the A and
C terminals when power is disconnected.
