DESCRIPTION

The HV control ECU transmits and receives signals to and from the ECM, battery ECU, skid control ECU, power steering ECU, and the gateway ECU via CAN (Controller Area Network) communication.






MONITOR DESCRIPTION

If the HV control ECU detects a malfunction in the CAN communication with the ECM or battery ECU, it illuminates the MIL and sets a DTC.

INSPECTION PROCEDURE

PROCEDURE

1. READ OUTPUT DTC (CODES ALL)
(a) Connect the Techstream to the DLC3.
(b) Turn the power switch ON (IG).
(c) Enter the following menus: Utility / All Codes.
(d) Read and record CAN communication malfunction DTCs.
Result:





HINT:
- When DTCs other than CAN communication malfunction DTCs are output simultaneously, first correct the CAN communication problem, and then perform troubleshooting for other DTCs.
- DTC P3108 (INF 594) is one of the DTCs that indicates a CAN communication malfunction.

B -- GO TO CAN COMMUNICATION SYSTEM
A -- Continue to next step.

2. CHECK TERMINAL OF ECM AND ECUS (+B1, +B2, CANH AND CANL TERMINALS)




(a) Check connection condition of each connector of the HV control ECU, ECM and battery ECU, as well as contact condition of each terminal shown in the table.






OK:
Connectors have been connected securely and there is no poor contact on each terminal.
NG -- CONNECT SECURELY
OK -- CHECK FOR INTERMITTENT PROBLEMS
