Replace combination switch ,

(a) Replace combination switch, refer to11.4.8.6 left front glass lifting switch replacement .

(b) Operated Left front window switch.

Confirm whether the left front window works normally.

3

Inspect the left front window anti-trapping control module power supply and the
grounding.

(a) Disconnect left front window anti-clamp module harness connector DR02.

(b) Measure terminal voltage by millimeter.

Test Terminal

Terminal voltage

DR02(2)－grounding 11-14V

DR02(2)－DR02(1) 11-14V

Confirm whether the measures value is normal.

4

Repair and replace the wire harness.

(a) Repair fault points between wire harness connector DR02 terminal No. 2 and fuse, DR02

terminal No. 2 and grounding circuit.

(b) Connect to harness connector DR02.

(c) Operate left front window switch.

Confirm whether the left front window works normally.

5

Inspect the circuit between the left front window anti-trapping control module and the left
front window switch.

Yes

The system is normal.

No

11.5.7.9 Left front window anti-clamp function invalidation

Circuit diagram:

See Front Left Door's Anti-jamming Window Does Not Work.

Diagnostic steps:

1

For initialization of the front left window, see 11.4.7.4 Initialization of Window Lifter
(such equipment anti-jamming function).

2

The BCM fault memory DTC code is read by a detector.

3

Repair the window. See11.4.7.7 Only Front Left Window Lifter Does Not Work (without
Anti-jamming Device).
