DESCRIPTION

These DTCs are stored when the clearance warning ECU assembly cannot receive and recognize several signals via the CAN communication line.

DTC No. Detection Item DTC Detection Condition Trouble Area
U010087 Lost Communication With ECM/PCM "A" Missing Message Lost communication with ECM CAN communication system
U012587 Lost Communication With Multi-axis Acceleration Sensor Module Missing Message Lost communication with yaw rate sensor (airbag sensor with ECU assembly) CAN communication system
U012987 Lost Communication With Brake System Control Module Missing Message Lost communication with skid control ECU (brake actuator assembly) CAN communication system
U014087 Lost Communication with Body Control Module Missing Message Lost communication with main body ECU (multiplex network body ECU) CAN communication system
U015587 Lost Communication with Instrument Panel Cluster (IPC) Control Module Missing Message Lost communication with the combination meter assembly CAN communication system
U016487 Lost Communication with HVAC Control Module Missing Message Lost communication with air conditioning amplifier assembly CAN communication system

HINT:

When 2 or more DTCs starting with "U" are output simultaneously, inspect the connectors and wire harnesses of each ECU.


PROCEDURE

1.CHECK DTC OUTPUT
a.

Clear the DTCs

Body Electrical > Clearance Warning > Clear DTCs
50002 438

b.

Check for CAN communication system DTCs

Body Electrical > Clearance Warning > Clear DTCs
50002 438

c.

Recheck for DTCs.

Body Electrical > Clearance Warning > Trouble Codes
50001 438

Result:
Result Proceed to
No CAN communication system DTCs are output A
CAN communication system DTCs are output B
