1.CHECK CURRENT DATA. Display {ECU ACC} using Subaru Select Monitor. | Does the current data indicate the standard value- | Diagnostics with Phenomenon > INSPECTION | Diagnostics with Phenomenon > INSPECTION |
2.CHECK HARNESS BETWEEN IG POWER SUPPLY — SRF CM. 1) Disconnect the SRF CM connector. 2) Turn the ignition switch to ON. 3) Measure the voltage between SRF CM connector and chassis ground. Connector & terminal (B42) No. 14 (+) — Chassis ground (−): | | Replace the SRF CM. Steering Responsive Fog Lights CM | Repair or replace the harness. |
3.CHECK INDICATOR OUTPUT. Turn the ignition switch to ON. | Does the warning indicator turn on for three seconds- | Diagnostics with Phenomenon > INSPECTION | Diagnostics with Phenomenon > INSPECTION |
4.CHECK CURRENT DATA. 1) Display «Indicator Signal» using Subaru Select Monitor. Read Current Data 2) Turn the ignition switch to ON. | Is it set as ON for 3 seconds- | Check the combination meter. Basic Diagnostic Procedure > PROCEDURE | Replace the SRF CM. Steering Responsive Fog Lights CM |
5.CHECK INDICATOR OUTPUT. Leave the ignition switch to ON for 10 seconds. | Does the warning indicator light go off- | Diagnostics with Phenomenon > INSPECTION | Diagnostics with Phenomenon > INSPECTION |
6.CHECK HEADLIGHT ASSEMBLY (ACTUATOR) DRIVE. 1) Connect the SRF 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- | Replace the SRF CM. Steering Responsive Fog Lights CM | Diagnostics with Phenomenon > INSPECTION |
7.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%-) | Diagnostics with Phenomenon > INSPECTION | Replace the SRF CM. Steering Responsive Fog Lights CM |
8.CHECK OUTPUT VOLTAGE BETWEEN HEADLIGHT ASSEMBLY (ACTUATOR). 1) Disconnect the SRF CM connector. 2) Turn the ignition switch to ON. 3) Measure the voltage between SRF CM connector and chassis ground. Connector & terminal (B42) No. 16 (+) — Chassis ground (−): | | Replace the headlight assembly. Headlight Assembly | Diagnostics with Phenomenon > INSPECTION |
9.CHECK HARNESS BETWEEN SRF CM AND HEADLIGHT ASSEMBLY (ACTUATOR). 1) Disconnect the connector of headlight assembly. 2) Measure the continuity between SRF CM connector and headlight assembly (actuator) connector. Connector & terminal • Headlight beam leveler RH (B42) No. 16 — (B487) No. 8:
(B42) No. 21 — (B487) No. 9:
(B42) No. 15 — (B487) No. 10: • Headlight beam leveler LH (B42) No. 16 — (B477) No. 8:
(B42) No. 21 — (B477) No. 9:
(B42) No. 15 — (B477) No. 10: | | Replace the SRF CM. Steering Responsive Fog Lights CM | Repair the open circuit or poor contact of the connector in the harness between headlight assembly and SRF CM. |
10.CHECK DTC. Display DTC using the Subaru Select Monitor. Read Diagnostic Trouble Code (DTC) | | Perform the diagnosis according to DTC. List of Diagnostic Trouble Code (DTC) > LIST | Replace the SRF CM. Steering Responsive Fog Lights CM |
