Subaru Legacy BN/BS (2015-2019) Service Manual / Continuously variable transmission(tr580) / Inhibitor switch / Inspection

When the driving condition or starter motor operation is improper, first check the shift linkage for improper operation. If the shift linkage is functioning properly, check the inhibitor switch.

1. Disconnect the ground terminal from battery sensor. NOTE

2. Remove the clip (A), and loosen the clamps (B) and (C).

3. Remove the air intake boot from the throttle body, and move it to the left side wheel apron.

4. Disconnect the transmission radio ground terminal and transmission harness connector, and remove the harness clip.

(A)	Transmission radio ground terminal
(B)	Transmission harness connectors
(C)	Harness clip

5. Remove the transmission case cover.

6. Move the lock lever in the arrow direction while pressing the lock button, and disconnect the connector.

(A)	Lock button

7. Attach the ST to the bulkhead harness. General Description > CAUTION

CHECK BOARD

8. Check for continuity in inhibitor switch circuit by shifting the select lever in “P”, “R”, “N” and “D” respectively.

NOTE:

• Check that there is no continuity in the starter circuit when the select lever is in the “R” and “D” ranges.

• When inhibitor switch is normal, check there is no poor contact in vehicle side connector and no open circuit in harness.

Signal sent to TCM	Range	Terminal No.	Standard
	P	38 — 42	Less than 1 -
	R	37 — 42
	N	36 — 42
	D	35 — 42

(A)	Check board connector

	Range	Terminal No.	Standard
Starter circuit	P/N	1 — 5	Less than 1 -
Back-up light circuit	R	2 — 3	Less than 1 -

9. Check that there is continuity at equal points when the select lever is moved 1.5° in both directions from the “N” range.

If there is continuity in only one direction or in other points, adjust the inhibitor switch. Inhibitor Switch > ADJUSTMENT

(A)	Continuity does not exist.
(B)	Continuity exists.
(C)	1.5°

10. Repeat the above inspection in other gear ranges. If there is fault, adjust the inhibitor switch and select cable. Inhibitor Switch > ADJUSTMENT Select Cable > ADJUSTMENT
