POSSIBLE

CAUSE

Note

DTC 03 is indicated when voltages in both of following wiring harnesses drop simultaneously.
— Wiring harness between fuse block connector (JB–01) terminal B and SAS control module

connector terminal 2E.

— Wiring harness between fuse block connector (JB–02) terminal D and SAS control module

connector terminal 2H.

Weak battery.

Malfunction in wiring harness between battery and SAS control module.
