Keyless Control Module
Locate keyless control module (keyless timer unit) behind rear seat. Leave keyless control module connector attached. Using DVOM, measure voltage at specified terminals of keyless control module connector (backprobe connector). See Fig 1 . Disconnect keyless control module connector and check for continuity at terminal "B" (ground). If voltage measurements or continuity are not as specified, check related components and wiring harnesses. If related components and wiring harnesses are okay, but system is still not functioning properly, replace keyless control module.
