Title: DOOR / HATCH: TAIL GATE: INSPECTION (2008 LX570)

INSPECTION

1. INSPECT BACK DOOR REMOTE CONTROL ASSEMBLY



(a) Measure the resistance according to the value(s) in the table below.

Standard Resistance:

Tester Connection

Switch Condition

Specified Condition

1 - 2

Back door remote control is pulled (On)

Below 1 Ω

1 - 2

Back door remote control is not pulled (Off)

10 kΩ or higher

If the result is not as specified, replace the back door remote control assembly.

2. INSPECT LOWER TAIL GATE LOCK ASSEMBLY LH

(a) Operation check:

(1) Set the lower tail gate lock LH to the full-latch position.

(2) Apply battery voltage and check operation of the lower tail gate lock motor LH.

OK:

Measurement Condition

Specified Condition

Battery positive (+) → Terminal 6 (ACT+)

Battery negative (-) → Terminal 5 (ACT-)

Latch turns to open-latch position

If the result is not as specified, replace the lower tail gate lock assembly LH.

(3) Set the lower tail gate lock LH to the half-latch position.

(4) Apply battery voltage and check operation of the lower tail gate lock motor LH.

OK:

Measurement Condition

Specified Condition

Battery positive (+) → Terminal 5 (ACT+)

Battery negative (-) → Terminal 6 (ACT-)

Latch turns to over-latch position

If the result is not as specified, replace the lower tail gate lock assembly LH.
