instrument panel harness to control
harness).
• J/C(6) (C-23) added between ABS-
ECU and 7
th terminal of junction
connector (C-20) between instrument
panel harness and control harness.
• J/C(6) (C-23) added between ABS-
ECU and 22
nd terminal of junction
connector (C-22) between instrument
panel harness and control harness.
ACD, AYC p.3-48• Circuit changed due to change in
branching point of connector for
4WD-ECU (C-37) (C-38) (from
instrument panel harness to control
harness).
