• Poor connection at keyless entry control unit-
Inspect harness connectors for backed out
terminals, improper mating, broken locks,
improperly formed or damaged terminals, and poo
r
terminal to wire connection.
• Damaged harness-Inspect the wiring harness fo
r
damage.
Check the Electro-Magnetic Interference (EMI)
• Location of vehicle check
Move the vehicle to a new location and perform
the check again.
• Non-OEM Parts.
