CAUTION / NOTICE / HINT

NOTICE:
·

Depending on the parts that are replaced during vehicle inspection or maintenance, performing initialization, registration or calibration may be needed.

·

Inspect the fuses for circuits related to this system before performing the following procedure.

·

When replacing the combination meter assembly, make sure to replace it with a new one. If a combination meter assembly which was installed to another vehicle is used, the information stored in the combination meter assembly will not match the information from the vehicle and a DTC may be stored.

·

Before measuring the resistance of the CAN bus, turn the ignition switch off and leave the vehicle for 1 minute or more without operating the key, switches or opening or closing the doors. After that, disconnect the cable from the negative (-) battery terminal and leave the vehicle for 1 minute or more before measuring the resistance.

·

After turning the ignition switch off, waiting time may be required before disconnecting the cable from the negative (-) battery terminal. Therefore make sure to read the disconnecting the cable from the negative (-) battery terminal notices before proceeding with work.

HINT:
·

Before disconnecting related connectors for inspection, push in on the connector body to check that each connector is not loose or disconnected.

·

When a connector is disconnected, check that the terminals and connector body are not cracked, deformed or corroded.

·

When the cable is disconnected / reconnected to the battery terminal, systems temporarily stop operating. However, each system has a function that completes learning the first time the system is used.

PROCEDURE

1.CHECK FOR CAN BUS WIRE (COMBINATION METER ASSEMBLY MAIN WIRE)

Pre-procedure1

a.

Disconnect the cable from the negative (-) battery terminal.


b.

Disconnect the I5 combination meter assembly connector.


Procedure1

c.

Measure the resistance according to the value(s) in the table below.

Standard Resistance:
Tester Connection Condition Specified Condition
I5-32 (TX+) - I5-15 (TX-) Cable disconnected from negative (-) battery terminal 108 to 132 Ω
I5-32 (TX+) - I26-4 (CG) Cable disconnected from negative (-) battery terminal 200 Ω or higher
I5-15 (TX-) - I26-4 (CG) Cable disconnected from negative (-) battery terminal 200 Ω or higher
I5-32 (TX+) - I26-16 (BAT) Cable disconnected from negative (-) battery terminal 6 kΩ or higher
I5-15 (TX-) - I26-16 (BAT) Cable disconnected from negative (-) battery terminal 6 kΩ or higher
