Subaru Legacy BN/BS (2015-2019) Service Manual / Continuously variable transmission(tr690) / 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. Remove the collector cover.

(1) Carefully pull up the rear of collector cover at two positions (A).

(2) Carefully pull up the front of collector cover at two positions (B) while moving it forward.

2. Disconnect the ground terminal from battery sensor. NOTE

3. Loosen the clamp (A) which connects the air intake boot.

4. Loosen the bolt (B) securing the air intake boot to the collector cover bracket.

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

6. Disconnect the inhibitor harness connector.

7. 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.
	P	4 — 3
	R	4 — 2
	N	4 — 1
	D	4 — 8
Starter circuit	P/N	12 — 11
Back-up light circuit	R	10 — 9

(A)	Inhibitor harness connector

8. 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°

9. 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
