controls the security lamp by sending a CAN message to the

speedometer. After the security lamp turns off following the

first four second illumination period, one of two events may

occur.

•

The lamp remains off. This indicates there are no current

fault conditions or stored DTCs currently detected by the

BCM.

•

If the lamp remains on beyond the four-second period, a

current DTC exists.

Check Engine Lamp

When the IGN is ON, the check engine lamp will illuminate for

approximately four seconds and then turn off. The ECM controls

the check engine lamp by sending a CAN message to the

speedometer. After the check engine lamp turns off following

the first four second illumination period, one of two events may

occur.

•

The lamp remains off. This indicates there are no current

fault conditions or stored DTCs currently detected by the

ECM.

•

If the lamp remains on beyond the four-second period, a

current DTC exists.

Neutral Indicator

ed03297

See Figure 4-14. The neutral indicator is controlled through

the (W) wire connected to the speedometer. When the trans-

mission is in neutral, the neutral switch closes and supplies a

ground to the BCM on terminal D3. The BCM then sends a

message to the speedometer over the CAN bus indicating the

transmission is in neutral. The speedometer supplies ground

to the neutral indicator causing it to illuminate.

ed03298

Figure 4-14. Oil Pressure Switch [120]

Oil Pressure Indicator

See Figure 4-14. The oil pressure indicator is connected to the

speedometer. The switch closes when oil pressure is low and

supplies ground to the BCM at terminal E3. The BCM then

sends a message to the speedometer over the CAN bus

indicating the oil pressure is low. The speedometer supplies

ground to the oil pressure indicator causing it to illuminate. This

is why the oil pressure indicator is illuminated with the IGN ON

and the engine OFF.

Turn Signal Indicators

Figure 4-12. Under Console [141]: FXS/B Typical

The turn signal indicators are controlled by the speedometer.

When the BCM receives a CAN bus message from the left or

right turn signal switch it flashes the correct turn signals. At the

ed03319

same time the BCM sends a message to the speedometer

over the CAN bus indicating which turn signal to operate. The

speedometer supplies ground to the corresponding turn signal

indicator causing it to illuminate.

High Beam Indicator

This circuit is grounded by the speedometer when the head-

lamp switch is placed in the high beam position. In the high

position, a message is sent over the CAN bus to the speedo-

meter and the BCM. The speedometer controls the indicator

and the BCM controls the headlamp.

Sender or fuel gauge not grounded.

See Figure 4-16. With IGN ON, the fuel gauge receives 12V

through the running lamp circuit. Current flows through the
