RKE System Does Not Program

CIRCUIT DESCRIPTION

When a program request has been selected with the Driver Information Center (DIC) switches and recognized by the CCM, the CCM's program request output grounds the PKE program request input, which is normally at a 5 volt level, for approximately 100 ms before allowing the program request input to return to a 5 volt level. This signal is read by the PKE program request input which supplies the 5 volt pull-up for the circuit. Refer to "Transmitter Programming" for programming procedures and information.

CHART TEST DESCRIPTION

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

1. Determines if the DIC switches are malfunctioning and setting CCM DTCs 13 or 14.

2. Determines if the 5 volt pull-up is present at the program request input of the PKE receiver.

3. Determines if the 5 volt pull-up is reaching the CCM program request output.

4. Determines if the PKE receiver is recognizing a manual program request.

5. Determines if the transmitter battery is weak or a possible antenna problem is present.

6. Determines if an antenna problem is present or if the transmitter to be programmed is at fault.

7. Determines if the transmitter or antenna is malfunctioning.

8. Checking for CCM causing the problem.

9. Checking for a short to ground in CKT 1455 or the PKE receiver being the cause of the problem.

10. Check for connector or terminal problem.

11. Check for incorrect programming procedures.

12. Check system by using another transmitter.

DIAGNOSTIC AIDS

If the problem is not a short to ground, check terminal connections thoroughly. Refer to "Intermittents and Poor Connections" in Diagram Information and Instruction.
