1.CHECK BODY INTEGRATED UNIT. Read the DTC of body integrated unit using Subaru Select Monitor. NOTE: For detailed procedures, refer to “Application help”. | | Perform the diagnosis according to DTC. | Day Time Running Light System > INSPECTION |
2.CHECK CURRENT DATA. Display the following items using Subaru Select Monitor. • «EPB Operating status» • «Shift position» • «Lighting II Switch Input» | Is the input signal normal- | Day Time Running Light System > INSPECTION | Check the defective part. |
3.CHECK FUSE. Check the headlight HI fuse (LH/RH). Relay and Fuse | | Day Time Running Light System > INSPECTION | |
4.CHECK HEADLIGHT ILLUMINATION. 1) Turn the ignition switch to ON. 2) Turn the lighting switch to the switch 2 (HEAD) position. 3) Turn the dimmer & passing switch to the switch UP position. | Does the headlight (high beam) illuminate- | Day Time Running Light System > INSPECTION | Check the combination switch (light) and headlight bulb. |
5.CHECK RELAY. Check the daytime running light relay (LH/RH) and headlight HI relay (LO/HI). Relay and Fuse | | Day Time Running Light System > INSPECTION | |
6.CHECK DAYTIME RUNNING LIGHT RESISTOR. Check the daytime running light resistor. Day Time Running Resistor > INSPECTION | Does the daytime running light resistor normal- | Day Time Running Light System > INSPECTION | Replace the daytime running light resistor. |
7.CHECK HARNESS. 1) Disconnect the connectors of body integrated unit, daytime running light relay, daytime running light resistor, and headlight. | | Replace the body integrated unit. Body Integrated Unit | Repair or replace the harness. |
