Inspection [08/2013 - ]
WARNING: This page is about a different car, the 2014 Lexus ES 300h. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
As the spiral cable with sensor sub-assembly may break, do not rotate the spiral cable with sensor sub-assembly more than the specified amount.
- INSPECT SPIRAL CABLE WITH SENSOR SUB-ASSEMBLY (w/o Steering Heater)
- Visually check for defects with the spiral cable with sensor sub-assembly.
- The defects are as follows:
- Scratches
- Small cracks
- Dents
- Chips
- Cracks or other damage to the connector
OK
No defects are found.
If any defects are found, replace the spiral cable with sensor sub-assembly with a new one.
- The defects are as follows:
- Check the spiral cable with sensor sub-assembly.TEXT IN ILLUSTRATION
*a Component without harness connected
(Spiral Cable with Sensor Sub-assembly)*b Color: Orange *c Color: Black - - Interlock - - NOTE:When rotating the spiral cable with sensor sub-assembly, make sure to push on the interlock indicated in the illustration to release the interlock mechanism.
- Set the spiral cable with sensor sub-assembly to the center position See step 6.
- Measure the resistance between each terminal of the spiral cable with sensor sub-assembly according to the table below.
