Inspection [08/2020 - ]: Procedure

INSPECT REAR HEIGHT CONTROL SENSOR SUB-ASSEMBLY LH (for 2WD)

Preparation for check

Confirm the standard, high and low positions of the link that will be used in the following inspection.

The standard position is 58° from the maximum link angle (high) and 51° from the maximum link angle (low).
The high position (+45°) is 13° from the maximum link angle (high).
The low position (-45°) is 6° from the maximum link angle (low).

*a	Standard Position	*b	Maximum Link Angle (Low)
*c	Maximum Link Angle (High)	*d	51°
*e	58°	*f	-45°
*g	+45°	*h	6°
*i	13°	-	-

Connect 3 dry cell batteries (1.5 V) in series.
NOTE:
Do not use rechargeable batteries as they may not output a voltage of 1.5 V.

Connect a positive (+) lead from the batteries to terminal 3 (SHB) and a negative (-) lead to terminal 1 (SHG).

*a	Component without harness connected (Rear Height Control Sensor Sub-assembly LH)	*b	Low
*c	Standard Position	*d	High
*e	-45°	*f	+45°

Measure the voltage between terminals 2 (SHRR) and 1 (SHG) while slowly moving the link up and down.

Standard Voltage

Tester Connection	Condition	Specified Condition
2 (SHRR) - 1 (SHG)	+45° (High)	4.5 V
2 (SHRR) - 1 (SHG)	0° (Standard position)	2.5 V
2 (SHRR) - 1 (SHG)	-45° (Low)	0.5 V

If the result is not as specified, replace the rear height control sensor sub-assembly LH.

INSPECT REAR HEIGHT CONTROL SENSOR SUB-ASSEMBLY LH (for AWD)

Check the rear height control sensor sub-assembly LH.

Connect 3 dry batteries of 1.5 V in series.

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).

NOTE:

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	Standard position (6.5° from horizontal position)
*c	Horizontal Position	*d	Height low (Full bound) (18.5° from standard position)
*e	Height high (Full rebound) (45.5° from standard position)	*f	Bound side link stop position (85° from standard position)
*g	Rebound side link stop position (102° from standard position)	-	-

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

Standard Voltage

Tester Connection	Condition	Specified Condition
1 (SHG) - 2 (SHRR)	Link moves upward from standard position to bound side (Height low)	From 18.5° to bound side link stop position	0.5 V
		18.5° (Full Bound)	1.69 V
	Horizontal Position	-	2.5 V
	Link moves downward from standard position to rebound side (Height high)	Standard position	2.79 V
		45.5° (Full Rebound)	4.5 V
		From 45.5° to rebound side link stop position	4.5 V

If the result is not as specified, replace the rear height control sensor sub-assembly LH.
