MONITOR DESCRIPTION
The hybrid vehicle control ECU assembly continuously monitors its main and sub CPUs. This self-check ensures that the hybrid vehicle control ECU assembly is functioning properly. If outputs from the CPUs are different and deviate from the standard, illuminate the MIL and store the DTC immediately.

HINT:
[*1] : Normal judgment procedure.
The normal judgment procedure is used to complete DTC judgment and also used when clearing permanent DTCs.
- Enter the following menus: Powertrain / Radar Cruise1 / Trouble Codes.
-
Read the DTCs.
HINT:
- If a DTC is output, the system is malfunctioning.
- If a DTC is not output, perform the following procedure.
-
If the DTCs are not output, perform a universal trip and check for permanent DTCs.
