1.CHECK CURRENT DATA.
Display «Control module voltage» using Subaru Select Monitor. Read Current Data">
Does the current data indicate the standard value?
Diagnostics with Phenomenon > INSPECTION">Go to Step 3.
Diagnostics with Phenomenon > INSPECTION">Go to Step 2.
2.CHECK HARNESS BETWEEN POWER SUPPLY — AUTO HEADLIGHT BEAM LEVELER CM.
1) Disconnect the auto headlight beam leveler CM connector.
2) Turn the ignition switch to ON.
3) Measure the voltage between the auto headlight beam leveler CM connector and chassis ground.

Repair the open circuit and poor contact of the connector in the harness between the auto headlight beam leveler CM and indicator.
9.CHECK HEADLIGHT ASSEMBLY (ACTUATOR) DRIVE.
1) Connect the auto headlight beam leveler CM connector.
2) Turn the ignition switch to ON, and within 10 seconds, repeat the OFF > Low beam of headlight switch 5 times.
3) Check that the headlight beam drops once, then returns to normal.
4) Then, after waiting for 30 seconds or more with the ignition ON, turn the ignition switch to OFF.
Does the headlight beam drop down once, and then return?

10.CHECK HEADLIGHT ASSEMBLY (ACTUATOR) OUTPUT.
1) Display «Actuator Signal» using Subaru Select Monitor. Read Current Data">
2) Turn the ignition switch to ON, and within 10 seconds, repeat the OFF > Low beam of headlight switch 5 times.
3) Check that the headlight beam drops once, then returns to normal.
4) Then, after waiting for 30 seconds or more with the ignition ON, turn the ignition switch to OFF.
Does the current data indicate the standard value? (Does the value change at 10 — 90%?)
