Troubleshooting

Make sure the D2D harness is connected and that 12 Volt is present between the red and black

wires. If 12 Volt is present, the module may be defective.

Ensure the correct programming procedure is being followed.

Reset the module and complete the programming again. If the issue persists, please contact

Technical Support.

(If compatible) when RXT mode is not desired or convenience features are needed, please reset

the and reprogram the module.

Normal operation.

Please follow the steps indicated in "Module programming" to complete the Key2GO

programming.

Normal operation.

Troubleshooting

Check the CAN2 Orange/Green and Orange/Brown wire connections. Wake up the data bus

by turning the ignition on and try again. If your installation does not require this connection, skip

this step by pressing the programming button 5 times.

Check the J1850 wire connection. Wake up the data bus by turning the ignition on and try

again.

Check the CAN1 Tan and Tan/Black wire connections. Wake up the data bus by turning the

ignition on and try again. If your installation does not require this connection, skip this step by

pressing the programming button 5 times.

Check the bypass line connection. If more than one wire is used, make sure they are not inverted.

Ensure the vehicle still operates correctly using the factory key.

The bypass calculation failed. Reset the module and try again. If the condition persists, please

contact Technical Support.

The Yellow/Black wire did not detect the expected signal. Refer to "Installation (wiring diagrams

& vehicle wiring reference charts)" to check the connections.

The Orange/Black wire did not detect the expected signal. Refer to "Installation (wiring diagrams

& vehicle wiring reference charts)" to check the connections.

The Violet/Green or Violet/Brown wire did not detect the expected voltage value. Refer to

"Installation (wiring diagrams & vehicle wiring reference charts)" to check the connections.

Troubleshooting

The diagnostic data bus was not detected, therefore the SmartStart features will be limited.
