WIRING DIAGRAM

INSPECTION PROCEDURE

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

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

2. 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.

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

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

   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)

1. Disconnect the A17 connector from the AFS ECU.

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

3. 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

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

B	REPLACE AFS ECU
C	PROCEED TO NEXT CIRCUIT INSPECTION SHOWN IN PROBLEM SYMPTOMS TABLE

A
REPAIR OR REPLACE HARNESS OR CONNECTOR (AFS ECU - HEIGHT CONTROL SENSOR REAR RH)
