PERFORM DTC CONFIRMATION PROCEDURE

CONSULT

1. Shift the selector lever to the P (Park) position.

2. Ignition switch ON and wait 5 seconds or more.

3. Shift the selector lever to the N (Neutral) position and wait 5 seconds or more.

4. Shift the selector lever to any position other than P (Park) and N (Neutral) and wait 5 seconds or more.

5. Select “Self Diagnostic Result” mode of “BCM”.

6. Check DTC.

Is DTC detected?

Refer to Diagnosis Procedure.

Inspection End.

CHECK TRANSMISSION RANGE FUNCTION

1. Ignition switch ON.

2. Select “SFT P -MET”, “SFT N -MET” and "SFT PN/N SW" in "Data Monitor" mode of "BCM(INTELLIGENT KEY)".

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?

Refer to Intermittent Incident.

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

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

CHECK DTC OF TCM

CONSULT

Select “Self Diagnostic Result” mode of “TRANSMISSION”.

Is DTC detected?

Perform the trouble diagnosis related to the detected DTC. Refer to DTC Index.

GO TO 3.

CHECK BCM INPUT SIGNAL

1. Ignition switch ON.

2. Check voltage between BCM harness connector and ground.

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

Is the inspection result normal?

GO TO 4.

GO TO 5.

REPLACE BCM

1. Replace BCM. Refer to Removal and Installation.

2. Perform initialization of BCM and registration of all Intelligent Keys. Refer to Work Procedure.

Inspection End.

CHECK BCM INPUT SIGNAL CIRCUIT

1. Ignition switch OFF.

2. Disconnect transmission range switch connector, BCM connector and ECM connector F79.

3. 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

4. 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?

GO TO 6.

Repair or replace harness.

CHECK INTERMITTENT INCIDENT

Refer to Intermittent Incident.

Inspection End.

CHECK TRANSMISSION RANGE SWITCH FUNCTION (METER)

CONSULT

1. Ignition switch ON.

2. Select “SHIFT IND” in “Data Monitor” mode of “METER_M&A”.

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?

Inspection End.
