Inspection
INSPECTION
PROCEDURE
1. INSPECT REAR HEIGHT CONTROL SENSOR SUB-ASSEMBLY LH
(a) Check the rear height control sensor sub-assembly LH.
(1) Connect 3 dry batteries of 1.5 V in series.
(2) Connect the positive (+) end of the batteries to terminal 3 (SHB) of the rear height control sensor sub-assembly LH and the negative (-) end of the batteries to terminal 1 (SHG). While slowly moving the sensor link up and down, measure the voltage between terminal 2 (SHRR) and terminal 1 (SHG).
NOTICE:
- Do not use rechargeable batteries as they may not output a voltage of 1.5 V.
- Do not apply a voltage of more than 6 V.
| *a | Component without harness connected (Rear Height Control Sensor Sub-assembly LH) | *b | Low |
| *c | Standard Position | *d | High |
| *e | -45° | *f | 12° |
| *g | +45° | - | - |
(3) Measure the voltage according to the value(s) in the table below.
Standard Voltage:
| Tester Connection | Condition | Specified Condition |
|---|---|---|
| 2 (SHRR) - 1 (SHG) | +45° (High) | Approx. 4.5 V |
| 0° (Standard position) | Approx. 2.25 V | |
| -45° (Low) | Approx. 0.5 V |
If the result is not as specified, replace the rear height control sensor sub-assembly LH.
