Inspect position lamp relay IR08 circuit.

(a) Turn off the ignition switch.

(b) Unplug position light relay IR08.

(c) Disconnect the light combination switch harness connector.

(d) Measure the resistance between terminal 1 of position light relay IR08 and fuse F05.

(e) Measure the resistance between terminal 3 of position light relay IR08 and fuse F05.

(f) Measure the resistance between terminal 2 of position light relay IR08 and terminal 19 of BCM harness

connector IP61.

Standard Resistance: Less than 1 Ω
