Solar Ventilation Control Module (SVCM)

  1. Locate SVCM in left rear of trunk compartment, above ventilation fans. Leave SVCM connecter attached. Using DVOM, measure voltage at specified terminals of SVCM connector (backprobe connector) within specified test conditions. See Fig 1 . If voltage measurements are as specified within specified conditions, go to next step. If voltage measurements are not as specified within specified conditions, check related components and wiring harnesses. If related components amd wiring harnesses are okay, but system is still not functioning properly, replace SVCM.
  2. Disconnect SVCM connector and check continuity at specified terminals between SVCM and SVCM harness connector within specified conditions. See Fig 2 . If continuity is not as specified within specified conditions, check related components and wiring harnesses. If related components amd wiring harnesses are okay, but system is still not functioning properly, replace SVCM.
