PROCEDURE
1. INSPECT NO. 1 HV BATTERY INTAKE FILTER
HINT:
If the vehicle is used in an area with heavy traffic or excessive dust,
or if the rear seat is used frequently, the No. 1 HV battery intake filter
may be clogged. Clean or replace the No. 1 HV battery intake fil
Open in Bus 3 Main Bus Line
DESCRIPTION There may be an open circuit in one of the CAN main bus lines when the resistance between terminals 6 (CA3H) and 21 (CA3L) of the central gateway ECU (network gateway ECU) is 70 Ω or higher. Symptom Trouble Area Resistance between terminals 6 (CA3H) and 21 (CA3L) of the central
