VEHICLE SPEED

BCM detects the following difference between 
the vehicle speed from combination meter and 
the one from “ABS actuator and electric unit 
(control unit)” for 10 seconds continuously
• One is 10 km/h (6.2 MPH) or more and the 

other is 4 km/h (2.5 MPH) or less.

• Harness or connectors

(The CAN communication line is open 
or shorted.)

• Combination meter
• ABS actuator and electric unit (control 

unit)

DTC CONFIRMATION PROCEDURE

1.

PERFORM DTC CONFIRMATION PROCEDURE

1.

Turn ignition switch ON and wait 2 seconds or more.

2.

Check DTC in “Self Diagnostic Result” mode of “BCM” using CONSULT.

Is DTC detected?

YES

>> Go to 

SEC-61, "Diagnosis Procedure"

.

NO

>> INSPECTION END

Diagnosis Procedure

INFOID:0000000007563277

1.

CHECK DTC OF IPDM E/R

Check DTC in “Self Diagnostic Result” mode of “IPDM E/R” using CONSULT. Refer to 

PCS-23, "DTC Index"

.

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Replace IPDM E/R. Refer to 

PCS-31, "Removal and Installation"

.

2.

CHECK INTERMITTENT INCIDENT

Refer to 

GI-40, "Intermittent Incident"

>> INSPECTION END

DTC No.

STARTER CONT RELAY

BCM detects a mismatch between the 
OFF request of starter control relay to 
IPDM E/R and the feedback.
(The feedback is ON instead of OFF.)

• Harness or connectors

(The CAN communication line is open 
or shorted.)

• IPDM E/R

Diagnosis Procedure

INFOID:0000000007563279

1.

CHECK CVT SHIFT SELECTOR POWER SUPPLY

1.

Turn ignition switch OFF.

2.

Disconnect CVT shift selector (detention switch) connector.

3.

SHIFT POSITION

BCM detects a difference between the P posi-
tion signal from CVT sift selector (detention 
switch) and the P position signal from IPDM 
E/R (CAN) for 2 seconds or more

• Harness or connectors

(The CAN communication line is 
open or shorted.)

• Harness or connectors
