INSPECTION PROCEDURE

PROCEDURE

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





(a) Disconnect the H26 connector from the height control sensor rear RH.
(b) Measure the voltage according to the value(s) in the table below.
Voltage:






NG -- INSPECT AFS ECU
OK -- Continue to next step.
2. INSPECT HEIGHT CONTROL SENSOR SUB-ASSEMBLY REAR RH
(a) Connect 3 dry cell batteries (1.5 V) in a series.
(b) Connect the positive (+) lead from the battery to terminal 1 and the negative (-) lead from the battery to terminal 3.
(c) Measure the voltage between terminal 2 and terminal 3 when slowly moving the link up and down.





Voltage:






NG -- REPLACE HEIGHT CONTROL SENSOR SUB-ASSEMBLY REAR RH
OK -- Continue to next step.
3. CHECK HARNESS AND CONNECTOR (AFS ECU - HEIGHT CONTROL SENSOR REAR RH)





(a) Disconnect the A14 connector from the AFS ECU.
(b) Disconnect the H26 connector from the height control sensor sub-assembly rear RH.
(c) Measure the resistance according to the value(s) in the following table.
Resistance:






Result:






C -- REPAIR OR REPLACE HARNESS OR CONNECTOR
B -- PROCEED TO NEXT CIRCUIT INSPECTION SHOWN IN PROBLEM SYMPTOMS TABLE
A -- REPLACE AFS ECU
4. INSPECT AFS ECU





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