If one-side terminator resistor is broken, the CAN communication will continue although noise suppression is deteriorated. No diagnostic trouble code
may be set even if the terminator resistor was broken. If a damage is found, replace the ECU which incorporates the defective terminator resistor.
CAN BUS LINE REPAIR HARNESS (PART NAME AND NUMBER)
Diagnostic Item 1
DIAGNOSTIC ITEM 1: Diagnose when the scan tool cannot receive the data sent by ETACS-ECU
CAUTION: When servicing a CAN bus line, ground yourself by touching a metal object such as an unpainted water pipe. If you fail to do so, a
component connected to the CAN bus line may be damaged.
CAN Communication Circuit
FUNCTION
When the CAN bus diagnosis is carried out, the scan tool communicates with the ETACS-ECU. If a communication flag is not set for the ETACS-ECU,
the ETACS-ECU will be diagnosed as a communication error.
TROUBLE JUDGMENT CONDITIONS
If a communication flag is not set for the ETACS-ECU, the Scan Tool determines that there is a failure.
TROUBLESHOOTING HINTS
-
Malfunction of the connector (data link connector or ETACS-ECU connector improperly connected)
-
Malfunction of the wiring harness (open circuit, short to ground, short to power supply between the data link connector and the ETACS-ECU
connector, line-to-line short, or power supply to the ETACS-ECU)
-
Malfunction of ETACS-ECU
