DTC U0164-827 - Lost Communication with A/C ECU

DESCRIPTION
The HV CPU transmits and receives signals via CAN communication with the engine CPU. The HV CPU and engine CPU also transmit and receive signals via CAN communication with the skid control ECU, main body ECU, and air conditioning amplifier assembly.









MONITOR DESCRIPTION

If the hybrid vehicle control ECU detects a problem with CAN communication with the ECM, it will illuminate the MIL and set a DTC.

INSPECTION PROCEDURE

PROCEDURE

1. CHECK DTC OUTPUT (ALL)
(a) Connect the Techstream to the DLC3.
(b) Turn the power switch on (IG).
(c) Check for DTCs of all systems by following the prompts on the tester screen.
(d) Check if DTCs are output.
Result:






B -- GO TO CAN COMMUNICATION SYSTEM
A -- REPLACE HYBRID VEHICLE CONTROL ECU
