SC9K-8 Keyless Entry Receiver/Transmitter Will Not Program

KEYLESS ENTRY RECEIVER/TRANSMITTER WILL NOT PROGRAM

SC9K-8:









Circuit Description

The keyless entry receiver applies voltage to CKT 1455. When the keyless programming connector terminals "A" and "B" are shorted together, the keyless entry receiver senses a voltage drop on CKT 1455. The keyless entry receiver then cycles all door lock motors once. The keyless entry receiver then waits for input from the transmitter(s) or for the jumper to be removed from the keyless programming connector.

Test Description

Number(s) below refer to circled number(s) on the diagnostic chart.

1. Check that the keyless entry receiver applies voltage to CKT 1455.

Diagnostic Aids

Program a known good transmitter and test the keyless entry system. If the keyless entry system operates normally, the original transmitter was defective. If the keyless entry receiver does not program, using a known good transmitter, replace the keyless entry receiver.
