Eclipse V6-3.0L SOHC (2003)
4. ECU COMM CHECK on the SWS monitor
Check whether the communication status of the input-or output-signal-side ECU associated with the defective function is normal.
-
If "OK" is displayed for all related ECUs, they communicate with each other normally and the input or output signal circuit system may be
defective. Therefore, check SWS monitor service data.
-
If "NG" is displayed for any of the related ECUs, something may be wrong with the ECU for which "NG" appears, its power supply or
grounding system, or a wiring harness or connector between the SWS monitor and the ECU. Check the wiring harness and connectors
associated with the ECU and examine the ECU itself.
5. Service data on the SWS monitor
Select the defective function from the function-specific diagnostic menu, and check the service data that appears for each function item.
NOTE: In addition to the function-specific diagnostic menu, a service data menu is available for SWS monitor service data to check all items for
each ECU.
1. When the SWS communication line is monitored.
You can determine whether the problem lies in the input or output signal circuit system by checking whether communication data is correct.
-
The switch condition does not meet the service data display: Input signal system related to defective functions
-
The switch condition meets the service data display: Output signal system related to defective functions
6. Check of input signal circuit system
Check relevant switch, sensor, input signal-side ECU and their wiring harness and connector.
7. Check of output signal circuit system
Check an output signal-side ECU, electrical load components and their wiring harness and connector.
