Diagnosis Procedure

Regarding Wiring Diagram information, refer to WIRING DIAGRAM .

1. CHECK IPDM E/R INPUT SIGNAL
   
   
   1. Turn ignition switch ON.
   2. Check voltage between IPDM E/R harness connector and ground.

      (+)		(-)	Condition		Voltage (V) (Approx.)
      IPDM E/R
      Connector	Terminal
      F42	40	Ground	Selector lever	P or N position	Battery voltage
      				Other than above	0

   Is the inspection result normal?

   YES 

   GO TO STEP 3  .

   NO 

   GO TO STEP 2  .

2. CHECK IPDM E/R INPUT SIGNAL CIRCUIT
   
   
   1. Turn ignition switch OFF.
   2. Disconnect IPDM E/R connector.
   3. Disconnect transmission range switch connector.
   4. Check continuity between IPDM E/R harness connector and transmission range switch harness connector.

      IPDM E/R		Transmission range switch		Continuity
      Connector	Terminal	Connector	Terminal
      F42	40	F52	10	Yes

   5. Check continuity between IPDM E/R harness connector and ground.

      IPDM E/R		Ground	Continuity
      Connector	Terminal
      F42	40		No

   Is the inspection result normal?

   YES 

   GO TO STEP 5  .

   NO 

   Repair or replace harness.

3. CHECK BCM INPUT SIGNAL
   
   
   1. Check voltage between BCM harness connector and ground.

      (+)		(-)	Condition		Voltage (V) (Approx.)
      BCM
      Connector	Terminal
      M98	102	Ground	Selector lever	P or N position	Battery voltage
      				Other than above	0

   Is the inspection result normal?

   YES 

   GO TO STEP 5  .

   NO 

   GO TO STEP 4  .

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

      BCM		Transmission range switch		Continuity
      Connector	Terminal	Connector	Terminal
      M98	102	F52	10	Yes

   5. Check continuity between IPDM E/R harness connector and ground.

      BCM		Ground	Continuity
      Connector	Terminal
      M98	102		No

   Is the inspection result normal?

   YES 

   GO TO STEP 5  .

   NO 

   Repair or replace harness.

5. REPLACE BCM
   
   
   1. Replace BCM. Refer to REMOVAL AND INSTALLATION .
   2. Perform initialization of BCM using CONSULT. Refer to the CONSULT Immobilizer mode and follow the on-screen instructions.
   3. Perform DTC CONFIRMATION PROCEDURE for B2605. Refer to DTC LOGIC .

   Is DTC B2605 detected again?

   YES 

   Replace IPDM E/R. Refer to REMOVAL AND INSTALLATION .

   NO 

   Inspection End.
