Keyless Unit
Locate keyless unit behind rear seat, in trunk/hatch compartment. Leave keyless unit connecter attached. Using DVOM, measure voltage at specified terminals of keyless unit connector (backprobe connector). SeeFig 1. Disconnect keyless unit connector and check continuity at terminal "B" (ground). If voltage measurements or continuity are not as specified, check related components and wiring harnesses. If related components amd wiring harnesses are okay, but system is still not functioning properly, replace keyless unit.
