Diagnostic Steps:

1

Inspect whether there is any DTC Code other than U1000

(a) Inspect whether there is any DTC Code other than U1000.

2

Inspect the communication of the left front lifting motor and
the BCM.

Yes

Go to

DTC list in 10.2.4.2

and repair according to

trouble codes.

No

(a) Turn the ignition switch to OFF position.

(b) Disconnect Left front side lifting motor

harness connector DR02.

(c) Disconnect BCM harness connector IP50.

(d) Measure left front lifter motor wire harness

connector DR02 terminal 4 and BCM wire
harness connector IP50 terminal 14.

Standard Resistance: Less than 1 Ω

(e) Measure resistance between left front lifte

motor wire harness connector DR02 terminal
14 and grounding.

Standard Resistance: 10 kΩ or higher

Is the resistance at a specified value?
