Adaptive Variable Suspension System -- Problem Symptoms Table


HINT:
  1. If a normal system code is displayed during the DTC check but the problem still occurs, check the circuits for each problem symptom in the order given in the table below and proceed to the relevant troubleshooting page.
  2. Inspect the fuse before inspecting the circuits shown in the chart below.
  3. Inspect each malfunction circuit in numerical order for the corresponding symptom.
  4. If any malfunction still exists even after checking and confirming that all the circuits are normal, replace the absorber control ECU.
