Lexus NX: Inspection

INSPECTION

PROCEDURE

1. INSPECT SPIRAL WITH SENSOR CABLE SUB-ASSEMBLY

NOTICE:

  • Do not remove the steering sensor from the spiral with sensor cable sub-assembly.
  • As the spiral with sensor cable sub-assembly may break, do not rotate the spiral with sensor cable sub-assembly more than the specified amount.

(a) Visually check for defects with the spiral with sensor cable sub-assembly.

(1) The defects are as follows:

  • Scratches
  • Small cracks
  • Dents
  • Chips
  • Cracks or other damage to the connector

OK:

No defects are found.

If any of the defects is found, replace the spiral with sensor cable sub-assembly with a new one.

(b) Check the spiral with sensor cable sub-assembly.

 Folding Motor Circuit

DESCRIPTION The fold seat control ECU receives switch operation signals from the No. 1 and No. 2 fold seat switches and activates the power seat motors. At this time, the Hall IC detects the actuation of the seat cushion and sends a seat cushion actuation signal to the fold seat control ECU. The fol
