(a) Disconnect the suspension control ECU S16 connector.
(b) Measure the resistance according to the values in the table below.
Standard resistance:






NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- REPLACE SUSPENSION CONTROL ECU
3. CHECK HARNESS AND CONNECTOR (DLC3 - BODY GROUND)





(a) Measure the resistance according to the value in the table below.
Standard resistance:










(b) Disconnect the suspension control ECU S16 connector.
(c) Measure the resistance according to the values in the table below.
Standard resistance:






NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.
4. CHECK HARNESS AND CONNECTOR (SUSPENSION CONTROL ECU - DLC3)
