For all Bullet EFI models (E5/C5/G5)
EFI Bullets, have a sophisticated ECU (Electronic Control unit). Big brands like to call this ECU the “on-board computer”. Well, there is an ECU on our Bullet, so our bullet is a …
Luckily, the ECU on the Bullet is simple and functional. You noticed already that a red indicator lamp glows when you put on the ignition switch. This is the MIL (Malfunction Indicator Led). It looks like a simple red light, but there is a sophisticated diagnose system behind.
Open the LH (Left Hand) triangle box behind the engine. In there you find the ECU (a black box with a lot of wires on). One of the wires is just a short end and seems to go nowhere. It is the open, single pole connector. Connect this open pole end with the mass (the chassis). The MIL offers you a blinking code which allows you to detect any defect sensor.
|MIL blink code||malfunction|
|MIL glows continuous. Engine starts but does not perform well.|
|Long 0 Short 6||Throttle position sensor|
|Long 0 Short 9||Manifold absolute pressure|
|Long 1 Short 1||Engine oil temperature|
|Long 1 Short 7||Lambda sensor|
|Long 4 Short 5||Lambda sensor heating|
|MIL glows continuous. Engine does not start.|
|Long 1 Short 5||Rollover sensor|
|Long 3 Short 3||Injector|
|Long 3 Short 7||Ignition coil|
|Long 4 Short 1||Fuel pump|
|Long 6 Short 6||Crankshaft position|
Advice: Make a small piece of electrical wire. Equip it with a connection to the open pole connector and a clamp to connect to a piece of the chassis nearby. Keep this piece of wire always with you.
