WIRING DIAGRAM
CAUTION / NOTICE / HINT
NOTICE:
- When the power management control ECU is replaced with a new one and the cable from the negative (-) battery terminal is connected, the power source mode becomes the on (IG) mode. When the battery is removed and reinstalled, the power source mode that was selected when the battery was removed is restored.
- Inspect the fuses for circuits related to this system before performing the following inspection procedure.
HINT:
Check the connector connection to the terminal to make sure that there is no abnormality such as a loose connection, deformation, etc.
PROCEDURE
|
1. |
CHECK LIN COMMUNICATION SYSTEM |
(a) Connect the Techstream to the DLC3.
(b) Turn the engine switch on (IG).
(c) Turn the Techstream on.
(d) Clear the DTCs (See page .gif)
).
(e) Check if DTC B2287 is output.
OK:
DTC B2287 is not output.
