WARNING: This page is about a different variant/trim than selected.

The relay electrical contacts in the multifunction alarm module may be pitted or sticking. Replace the module, if gently tapping or wiggling the module causes a change in the relay's operation.
The performance of the multifunction alarm module may be affected by temperature. Check the module operation after sitting outside overnight and after running the engine for 30 minutes.
If the EFI fuse opens during cranking, check for a shorted fuel pump/circuit. The EFI relay supplies current to the circuit opening relay that supplies power to the fuel pump. The circuit opening relay is energized during cranking and when reference pulses are detected by the PCM.
