Keyless Control Module

  1. Remove rear package tray. Locate keyless control module behind rear seat, in trunk/hatch compartment. Leave keyless control module harness connector attached. Using DVOM, measure voltage at specified terminals of keyless control module connector (backprobe connector). See Fig 1 .
  2. Disconnect harness connector before checking continuity at terminal "B" (ground). If voltage measurements or continuity are not as specified, check related components and wiring harnesses. If items are okay, but system is still not functioning properly, replace keyless control module.
