Diagnosis Procedure

Regarding Wiring Diagram information, refer to WIRING DIAGRAM .

1. CHECK CVT SHIFT SELECTOR SWITCH FUNCTION
   
   
   1. Turn ignition switch ON.
   2. Select "SFT P -MET", "SFT N -MET" and "SFT PN/N SW" in DATA MONITOR mode with CONSULT.
   3. Check "SFT P -MET", "SFT N -MET" and "SFT PN/N SW" indication under the following conditions.

      Monitor item	Condition		Indication
      SFT P -MET	CVT Shift selector	Selector lever is in any position except the P (Park) position	OFF
      		Selector lever is in the P (Park) position	ON
      SFT N -MET	CVT Shift selector	Selector lever is in any position except the N (Neutral) position	OFF
      		Selector lever is in the N (Neutral) position	ON
      SFT PN/N SW	CVT Shift selector	Selector lever is in and position except the P (Park) or N (Neutral) position	OFF
      		Selector lever is in the P (Park) or N (Neutral) position	ON

   Is the inspection result normal?

   YES 

   Refer to INTERMITTENT INCIDENT .

   NO-1 

   If SFT N -MET or SFT P -MET is incorrect. GO TO 7.

   NO-2 

   If SFT PN/N SW is incorrect. GO TO 2.

2. CHECK DTC OF TCM
   
   

   Check DTC in "Self-Diagnostic Result" mode of "TCM" using CONSULT.

   Is DTC detected?

   YES 

   Perform the trouble diagnosis related to the detected DTC. Refer to DTC LOGIC (RE0F10E) or DTC LOGIC (RE0F10J).

   NO 

   GO TO STEP 3  .

3. CHECK BCM INPUT SIGNAL
   
   
   1. Turn ignition switch ON.
   2. Check voltage between BCM harness connector and ground.

      (+)		(-)	Condition		Voltage (V) (Approx.)
      BCM
      Connector	Terminal
      M18	39	Ground	Selector lever	P (Park) or N (Neutral) position	12
      				Other than above	0

   Is the inspection result normal?

   YES 

   GO TO STEP 4  .

   NO 

   GO TO STEP 5  .

4. REPLACE BCM
   
   
   1. Replace BCM. Refer to REMOVAL AND INSTALLATION .
   2. Perform initialization of BCM and registration of all Intelligent Keys using CONSULT.

   Inspection End.

5. CHECK BCM INPUT SIGNAL CIRCUIT
   
   
   1. Turn ignition switch OFF.
   2. Disconnect transmission range switch connector.
   3. Disconnect BCM connector.
   4. Check continuity between transmission range switch harness connector and BCM harness connector.

      Transmission range switch		BCM		Continuity
      Connector	Terminal	Connector	Terminal
      F29	10	M18	39	Yes

   5. Check continuity between transmission range switch harness connector and ground.

      Transmission range switch		Ground	Continuity
      Connector	Terminal
      F29	10		No

   Is the inspection result normal?

   YES 

   GO TO STEP 6  .

   NO 

   Repair or replace harness.

6. CHECK INTERMITTENT INCIDENT
   
   

   Refer to INTERMITTENT INCIDENT .

   Inspection End.

7. CHECK CVT SHIFT SELECTOR RANGE SWITCH FUNCTION (METER)
   
   
   1. Turn ignition switch ON.
   2. Select "SHIFT IND" in DATA MONITOR mode (METER) with CONSULT.
   3. Check "SHIFT IND" indication under the following conditions.

      Monitor item	Condition		Indication
      SHIFT IND	CVT Shift selector	P (Park) position	P
      		N (Neutral) position	N

   Is the inspection result normal?

   YES 

   Inspection End.

   NO 

   Refer to COMPONENT INSPECTION (RE0F10E) or COMPONENT INSPECTION (RE0F10J).
