Keyless Unit
Remove keyless unit from bracket behind glove box. See Figure . Leave keyless unit connector attached. Using DVOM, measure voltage at specified terminals of keyless unit connector (backprobe connector). See Fig 1 . See KEYLESS UNIT CONNECTOR PIN VOLTAGES table. Disconnect keyless unit connector and check continuity at terminal "C" (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 unit.
