Detention Switch Circuit Check

WARNING: This page is about a different car, the 2004 Nissan Murano. However, it is still accessible from the selected car via links, so may be relevant.

CHECK FUNCTION

With CONSULT-II

Check that when the CVT selector lever is in P position, "DETENT SW" on the DATA MONITOR becomes OFF.

Without CONSULT-II

GO TO 2.

OK or NG

OK: Detention switch circuit is OK.
NG: GO TO 2.

CHECK DETENTION SWITCH POWER SUPPLY
1. Do insert the key to key cylinder.
2. Disconnect CVT device [detention switch (key)] connector.
3. Check voltage between CVT device [detention switch (key)] connector M57 terminal 5 (B/R) and ground.
  5 (B/R) - Ground: Battery voltage.
OK or NG
1. OK: GO TO 4.
2. NG: GO TO 3.

CHECK DETENTION SWITCH HARNESS
1. Turn ignition switch OFF.
2. Disconnect CVT device [detention switch (key)] connector and "key switch and key lock solenoid" connector.
3. Check continuity between CVT device [detention switch (key)] connector M57 terminal 5 (B/R) and key switch and key lock solenoid connector M28 terminal 4 (B/R).
  5 (B/R) - 4 (B/R): Continuity should exist
4. Check continuity between CVT device [detention switch (key)] connector M57 terminal 5 (B/R) and ground.
  5 (B/R) - Ground: Continuity should not exist.

OK or NG
1. OK: Check the condition of the harness and connector.
2. NG: Repair or replace harness between CVT device [detention switch (key)] and key switch and key lock solenoid.

CHECK DETENTION SWITCH

Check continuity between detection switch as follows.

CONTINUITY CHECK CHART

OK or NG

OK: GO TO 5.
NG: Replace CVT device [detention switch (key)].

CHECK DETENTION SWITCH SIGNAL CIRCUIT HARNESS CONTINUITY
1. Disconnect driver seat control unit connector.
2. Check continuity between driver seat control unit connector B303 terminal 21 (R/L) and CVT device [detention switch (key)] connector M57 terminal 6 (L).
  21 (R/L) - 6 (L): Continuity should exist.
3. Check continuity between driver seat control unit connector B303 terminal 21 (R/L) and ground.
  21 (R/L) - Ground: Continuity should not exist.
