B1A7D-01

B1A7D-01-START BUTTON - GENERAL ELECTRICAL FAILURE





For a complete wiring diagram, refer to the Wiring Information.

- When Monitored:
Any time the Start/Stop Button is pressed, the Radio Frequency Hub (RF Hub) will check the (D122) Security K Line Communication circuit and the (G201) Ignition Switch Position Signal circuit. It samples these circuits every 10ms. while the button is pressed.

- Set Condition:
If these two circuits do not match, during a button press, this code will set.





1. CHECK FOR AN ACTIVE DTC
1. Using the scan tool, record and erase the DTCs.
2. Turn the ignition to the Lock position.
3. Try to start the engine and allow to run for 30 seconds.
4. Turn the ignition off and then back on.
5. Using the scan tool, read the active DTCs.

Does the scan tool display; B1A7D-01-START BUTTON - GENERAL ELECTRICAL FAILURE?

Yes

- Go To 2

No

- Test complete, the condition or conditions that originally set this DTC are not present at this time. Using the wiring diagrams as a guide, check all related splices and connectors for signs of water intrusion, corrosion, pushed out or bent terminals and poor pin fit.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

2. CHECK THE (D122) SECURITY K LINE COMMUNICATION CIRCUIT




1. Turn the ignition off.
2. Disconnect the Keyless Ignition Node harness connector.
3. Measure the voltage between ground and the (D122) Security K Line Communication circuit.

Is the voltage above 12.0 volts?

Yes

- Go To 3

No

- Repair the open in the (D122) Security K Line Communication circuit.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

3. (G201) IGNITION SWITCH POSITION SIGNAL SHORTED TO GROUND




1. Measure the resistance between ground and the (G201) Ignition Switch Position Signal circuit.

Is the resistance below 1500 Ohms?

Yes

- Repair the short to ground in the (G201) Ignition Switch Position Signal circuit.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No

- Go To 4

4. (G201) IGNITION SWITCH POSITION SIGNAL SHORTED TO BATTERY




1. Measure the voltage between ground and the (G201) Ignition Switch Position Signal circuit.

Is there any voltage present?

Yes

- Repair the short to voltage in the (G201) Ignition Switch Position Signal circuit.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No

- Replace the Keyless Ignition Node (KIN). Keyless Ignition Node Receiver - Removal.
- Perform the BODY VERIFICATION TEST. Body Verification Test.
