ADAPTIVE VARIABLE SUSPENSION SYSTEM TERMINALS OF ECU

INSPECT BATTERY VOLTAGE

1. Measure the voltage of the battery.

   CHECK ABSORBER CONTROL ECU

   
   

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

      Note

      Inspect the connectors from the back side while the connectors are connected.
