INSPECTION PROCEDURE

1.CHECK HARNESS AND CONNECTOR (HEIGHT CONTROL SENSOR SUB-ASSEMBLY REAR RH POWER SOURCE)


    E069138E01

  1. Disconnect the H26 connector from the height control sensor rear RH.

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

    Voltage:
    Tester connection
    		Condition
    		Specified condition
    SHB (H26-3) - SHG (H26-1)
    		Ignition switch ON
    		4.5 to 5.5 V



NG
Go to step 4
OK


2.INSPECT HEIGHT CONTROL SENSOR SUB-ASSEMBLY REAR RH

  1. Connect 3 dry cell batteries (1.5 V) in a series.

  1. Connect the positive (+) lead from the battery to terminal 1 and the negative (-) lead from the battery to terminal 3.



  1. Measure the voltage between terminal 2 and terminal 3 when slowly moving the link up and down.


    E068634E01

    Voltage:
    Link Angle
    		Standard voltage
    +45°(High)
    		4.5 V
    0°(Normal)
    		2.5 V
    -45°(Low)
    		0.5 V



NG
REPLACE HEIGHT CONTROL SENSOR SUB-ASSEMBLY REAR RH
OK


3.CHECK HARNESS AND CONNECTOR (AFS ECU - HEIGHT CONTROL SENSOR REAR RH)


    E075754E02

  1. Disconnect the A17 connector from the AFS ECU.

  1. Disconnect the H26 connector from the height control sensor sub-assembly rear RH.

  1. Measure the resistance according to the value(s) in the following table.

    Resistance:
    Tester connection
    		Condition
    		Specified condition
    SHRL (A17-9) - SHRR (H26-2)
    		Always
    		Below 1 Ω
    SHRL (A17-9) - Body ground
    		Always
    		10 kΩ or higher

    Result:
    Condition
    		Proceed to
    OK (When checking from the DTC)
    		A
    OK (When checking from the PROBLEM SYMPTOMS TABLE)
    		B
    NG
    		C



B
PROCEED TO NEXT CIRCUIT INSPECTION SHOWN IN PROBLEM SYMPTOMS TABLE

C
REPAIR OR REPLACE HARNESS OR CONNECTOR
A

REPLACE AFS ECU 

4.INSPECT AFS ECU


    E069130E06

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

    Voltage:
    Tester connection
    		Condition
    		Specified condition
    SBR (A17-10) - SGR (A17-20)
    		Ignition switch ON
    		4.5 to 5.5 V

    Result:
    Condition
    		Proceed to
    OK
    		A
    NG (When checking from the DTC)
    		B
    NG (When checking from the PROBLEM SYMPTOMS TABLE)
    		C
