|
DTC |
U1002 (CAN MS BUS) |
Lost Communication with Gateway Module (Main body ECU) |
DESCRIPTION
If 2 or more DTCs are output during the DTC check, one side of the CAN branch wire may be open (One side of the CANH [branch wire]/CANL [branch wire] of the ECU and/or sensor is open).

- *1: w/ Seat Position Memory System
- *2: w/ Power Back Door
- *3: w/ Power Slide Door
WIRING DIAGRAM
CAUTION / NOTICE / HINT
NOTICE:
- Turn the ignition switch off before measuring the resistances between CAN bus main wires and between CAN bus branch wires.
- Turn the ignition switch off before inspecting CAN bus wires for a ground short.
- After the ignition switch is turned off, check that the key reminder warning system and light reminder warning system are not operating.
- Before measuring the resistance, leave the vehicle as is for at least 1 minute and do not operate the ignition switch, any other switches or the doors. If any doors need to be opened in order to check connectors, open the doors and leave them open.
HINT:
- Operating the ignition switch, any other switches or a door triggers related ECU and sensor communication on the CAN. This communication will cause the resistance value to change.
- Even after DTCs are cleared, if a DTC is stored again after driving the vehicle for a while, the malfunction may be occurring due to vibration of the vehicle. In such a case, wiggling the ECUs or wire harness while performing the inspection below may help determine the cause of the malfunction.
PROCEDURE
|
1. |
PRECAUTION |
NOTICE:
After turning the ignition switch off, waiting time may be required before disconnecting the cable from the battery terminal. Therefore, make sure to read the disconnecting the cable from the battery terminal notice before proceeding with work (See page
![2016 MY Sienna [12/2015 - 08/2016]; INTRODUCTION: REPAIR INSTRUCTION: PRECAUTION](/t3Portal/stylegraphics/info.gif)
).
|
|
2. |
DISCONNECT CABLE FROM NEGATIVE BATTERY TERMINAL |
(a) Disconnect the cable from the negative (-) battery terminal before measuring the resistances of the main wire and the branch wire.
CAUTION:
Wait at least 90 seconds after disconnecting the cable from the negative (-) battery terminal to disable the SRS system.
NOTICE:
When disconnecting the cable, some systems need to be initialized after the cable is reconnected (See page
).
