INSPECTION PROCEDURE

PROCEDURE

1. READ VALUE USING TECHSTREAM (HEIGHT SENSOR)
(a) Check the DATA LIST for proper functioning of the height sensor.

AFS





OK:
Condition value will be displayed.
OK -- REPLACE AFS ECU
NG -- Continue to next step.
2. CHECK WIRE HARNESS (ECU - SENSOR)




(a) Disconnect the A30*1 or A31*2 ECU connector.
(b) Disconnect the H11*1 or H17*2 sensor connector.
HINT:
*1: Front
*2: Rear
(c) Measure the resistance of the wire harness side connectors.
Standard resistance:
Front





Rear





NG -- REPAIR OR REPLACE HARNESS AND CONNECTOR
OK -- Continue to next step.
3. INSPECT FRONT HEIGHT CONTROL SENSOR SUB-ASSEMBLY




(a) Connect 3 dry cell batteries (1.5 V) in series.
(b) Connect the dry cell battery positive (+) terminal to terminal 1 (SHB) and the negative one to terminal 4 (SHG) to apply the voltage of 4.5 V between terminals 1 (SHB) and 4 (SHG).
(c) While slowly moving the link up and down with the voltage being applied, measure the voltage between terminals 2 (SHFL) and 4 (SHG).
Standard voltage:






NG -- REPLACE FRONT HEIGHT CONTROL SENSOR SUB-ASSEMBLY
OK -- Continue to next step.
4. INSPECT REAR HEIGHT CONTROL SENSOR SUB-ASSEMBLY




(a) Connect 3 dry cell batteries (1.5 V) in series.
(b) Connect the dry cell battery positive (+) terminal to terminal 3 (SHB) and the negative one to terminal 1 (SHG) to apply the voltage of 4.5 V between terminals 3 (SHB) and 1 (SHG).
(c) While slowly moving the link up and down with the voltage being applied, measure the voltage between terminals 2 (SHRL) and 1 (SHG).
Standard voltage:






NG -- REPLACE REAR HEIGHT CONTROL SENSOR SUB-ASSEMBLY
OK -- REPLACE AFS ECU
