U1000 can comm
Description
Refer to LAN-7, "CAN COMMUNICATION SYSTEM : System Description".
Dtc logic
Dtc detection logic
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 present dtc by performing the self diagnostic result procedure.
Consult display | Dtc detection condition | Possible cause |
Can comm circuit [u1000] | When any listed module cannot communicate with can communication signal continuously for 2 seconds or more with ignition switch on | In CAN communication system, any item (or
items) of the following listed below is malfunctioning.
|
Diagnosis procedure
1. Perform self diagnostic result
Is “can comm circuit” displayed? Yes >> perform can diagnosis as described in diagnosis section of consult operation manual.
No >> refer to gi-39, "intermittent incident".

Control unit (can) [u1010] | Bcm detected internal can communication circuit malfunction. | Bcm |
Diagnosis procedure
1.Replace bcm
When dtc “u1010” is detected, replace bcm.
>> Replace bcm. Refer to bcs-126, "removal and installation".
Power supply and ground circuit
Diagnosis procedure
Regarding wiring diagram information, refer to bcs-111, "wiring diagram".
1.Check fuses and fusible link
Check that the following fuses and fusible link are not blown.
Is the fuse blown? Yes >> replace the blown fuse or fusible link after repairing the affected circuit.
No >> go to 2.
2.Check power supply circuit
Is the inspection result normal? Yes >> go to 3.
No >> repair harness or connector.
3.Check ground circuit
Check continuity between bcm connector and ground.
Is the inspection result normal? Yes >> inspection end.
No >> repair harness or connector.
Combination switch input circuit
Diagnosis procedure
Regarding wiring diagram information, refer to bcs-111, "wiring diagram".
1.Check input 1 - 5 circuit for open
Is the inspection result normal? Yes >> go to 2.
No >> repair harness or connectors.
2.Check input 1 - 5 circuit for short
Check for continuity between bcm connector and ground.
Is the inspection result normal? Yes >> repair harness or connectors.
No >> go to 3.
3.Check bcm output voltage
Is the inspection result normal? Yes >> replace combination switch.
No >> replace bcm. Refer to bcs-126, "removal and installation".
Combination switch output circuit
Diagnosis procedure
Regarding Wiring Diagram information, refer to BCS-111, "Wiring Diagram".
1.Check output 1 - 5 circuit for open
Is the inspection result normal? Yes >> go to 2.
No >> repair harness or connectors.
2.Check output 1 - 5 circuit for short
Check for continuity between bcm connector and ground.
Is the inspection result normal? Yes >> repair harness or connectors.
No >> go to 3.
3.Check bcm input signal
Is the inspection result normal? Yes >> replace bcm. Refer to bcs-126, "removal and installation".
No >> replace combination switch.
