nction (BCM - COMMON ITEM)INFOID:0000000009941330
CAUTION:
After disconnecting the CONSULT vehicle interface (VI) from the data link connector, the ignition must
be cycled OFF → ON (for at least 5 seconds) → OFF. If this step is not performed, the BCM may not go
to ”sleep mode”, potentially causing a di scharged battery and a no-start condition.
APPLICATION ITEM
CONSULT performs the following functions via CAN communication with BCM.
SYSTEM APPLICATION
BCM can perform the following functions.
Direct Diagnostic Mode Description
Ecu Identification The BCM part number is displayed.
Self Diagnostic Result The BCM self diagnostic results are displayed.
Data Monitor The BCM input/output data is displayed in real time.
Active Test The BCM activates outputs to test components.
Work support The settings for BCM functions can be changed.
Configuration • The vehicle specification can be read and saved.
• The vehicle specification can be written when replacing BCM.

NOTE:
U1000 can be set if a module harness was disconnected and reconnected, perhaps during a repair. Confirm
that there are actual CAN diagnostic symptoms and a pr esent DTC by performing the Self Diagnostic Result
procedure.
Diagnosis ProcedureINFOID:0000000009461633
1. PERFORM SELF DIAGNOSTIC RESULT
1. Turn ignition switch ON and wait for 2 second or more.
2. Check “SELF- DIAG RESULTS”.
Is
“CAN COMM CIRCUIT” displayed?
YES >> Perform CAN Diagnosis as described in DIAG NOSIS section of CONSULT Operation Manual.
NO >> Refer to GI-43, "Intermittent Incident"
.

• If DTC B260A is displayed with DTC B261A, first perform the trouble diagnosis for DTC B261A. Refer to
PCS-68, "DTC Logic"
.
DTC CONFIRMATION PROCEDURE
1. PERFORM SELF DIAGNOSTIC RESULT
1. Turn ignition switch ON under the following conditions, and wait for at least 2 seconds.
- CVT selector lever is in the P (park) or N (neutral) position.
- Release the brake pedal.
2. Perform self diagnostic result.
Is DTC B260A detected?
YES >> Refer to PCS-58, "Diagnosis Procedure".
NO >> Inspection End.
Diagnosis ProcedureINFOID:0000000009461637
Regarding Wiring Diagram information, refer to PCS-44, "Wiring Diagram".
1. CHECK SELF DIAGNOSTIC RESULT FOR IPDM E/R
Perform self diagnostic result for IPDM E/R.
Are any DTCs detected?
YES >> Refer to PCS-20, "DTC Index".
NO >> GO TO 2
2. CHECK IGNITION RELAY-1 POWER SUPPLY (IPDM E/R)
Check voltage between IPDM E/R connector E63 terminal 43 and ground.
Is the inspection result normal?
YES >> Replace IPDM E/R. Refer to PCS-32, "Removal and Installation".
NO >> GO TO 3.
3. CHECK IGNITION RELAY-1 POWER SUPPLY (BCM)
Check voltage between BCM connector M18 terminal 70 and ground.
