DTC Description

WARNING: This page is about a different variant/trim than selected.

When the enable conditions are satisfied the PCM checks that high and low outputs (voltage level) are observed when VFS's are commanded. When an VFS output failure is detected, the appropriate fail counter is incremented. If the failure threshold exceeds 5 seconds during one diagnostic test (10 seconds), the test has failed and a P007700 DTC is stored.
