1. Inspect the display of DTC U0100, U0121, U0140 and/or U0415 using the M-MDS. (See 09-02D-7 DTC
TABLE[MULTIPLEX COMMUNICATION SYSTEM].)
2. Referring to the following table, determine the malfunctioning part of the CAN system.
×: Normal
— : Communication error
DSC HU/CM
1. Inspect the display of DTC U0100, U0101, U0114, U0140, U1900 and/or U2023 using the M-MDS. (See 09-
02D-7 DTC TABLE[MULTIPLEX COMMUNICATION SYSTEM].)
Caution
• DTC U2023 may not be cleared during engine starting even if DTC clearing is done using the M-
MDS. When clearing DTC U2023, execute with the ignition switch in the ON position (Engine off).
Note
• You may want to check which unit is malfunctioning according to Freeze Frame Data. "Electrical" > "IC
Service Function" > "Freeze Frame Data".This function is supported on IDS, not PDS.

— : Communication error
BCM
Note
• There is no DTC in the BCM that determines signal quality between it and the other module. Due to this,
determine the malfunction location using the DTC on the other module side.
