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.
Detection Item |
Trouble Area |
---|---|
Resistance between terminals 6 (CA3H) and 21 (CA3L) of central gateway ECU (network gateway ECU) is 70 Ω or higher. |
|
This malfunction is not related to the lines of a CAN branch or to ECUs or sensors connected to a CAN branch.

Vehicle load limits
Vehicle load limits include total load capacity, seating capacity, TWR (Trailer
Weight Rating) and cargo capacity.
■ Total load capacity (vehicle capacity weight):
Total load capacity means the combined weight of occupants, cargo and luggage.
■ Seating capacity:
Regular Cab models ...
If you have a flat tire
Remove the flat tire and replace it with the spare provided.
■ Before jacking up the vehicle
● Stop the vehicle on a hard, flat surface.
● Set the parking brake.
● Shift the shift lever to P (automatic transmission) or R (manual transmission).
● Stop the engine.

Fuel pump shut off system
To minimize the risk of fuel leakage when the engine stalls or an airbag inflates
upon collision, the fuel pump shut off system stops supplying fuel to the engine.
Follow the procedure below to restart the engine after the system is activated.
Turn the engine switch to the ACC
