When a MyKey® administrator has set the AdvanceTrac® feature to always on and a MyKey® programmed key is in use, the traction control system cannot be disabled. The menu selection in the message center used to disable the traction control system does not display when a MyKey® is in use, but remains active for the MyKey® administrator to select the AdvanceTrac® always on feature off. The stability-traction control indicator still functions normally to indicate a stability-traction control system fault and a stability-traction control active event.

Component Description

Brake Fluid Level Switch

The brake fluid level switch is mounted in the master cylinder reservoir and is hardwired to the BCM through a signal circuit. The brake fluid level switch is grounded through a separate body ground circuit. The BCM provides a reference voltage to the brake fluid level switch. When the brake fluid level is low the switch closes, pulling the reference voltage low. When the brake fluid level is high, the switch opens, sending the reference voltage high on the signal circuit to the BCM. The brake fluid level switch uses an internal resistor in parallel. This enables the BCM to differentiate between a disconnected brake fluid level switch connector and a full level condition.

Fuel Level Sender (Float and Card)

The fuel level sender is mounted to the fuel pump and sender unit. The fuel level sender is a dual sweep potentiometer style resistor connected to a float mechanism. The dual sweep design provides a second resistance measurement that reduces the intermittent loss of data due to corrosion between the resistor wires and the sweep arm. As the fuel level changes, the float rises or falls with the fuel level moving the sweep arm across the resistor wires. This movement either increases or decreases the resistance through the unit. The fuel level sensor resistance ranges from 180 ohms +/- 4 ohms at empty (E) to 10 ohms +/- 2 ohms at full (F). When the fuel level is low, the fuel level sensor resistance is high. When the fuel level is high, the fuel level sensor resistance is low.

The fuel pump and sender unit is hardwired to the IPC through separate signal and return circuits. The fuel level return circuits are grounded internally in the IPC. The IPC provides a reference voltage on the fuel level signal circuit. As the fuel level changes, the change in resistance raises or lowers the fuel level signal voltage depending on the resistance of the fuel level sender.

IPC

The IPC provides the driver with a system status and alerts the driver when certain conditions exist in the vehicle. The IPC receives the ignition status from the BCM over the MS-CAN. The IPC requires PMI when replaced.

Key-In-Ignition Switch

The key-in-ignition is part of the ignition switch. When the key is inserted into the ignition lock cylinder, voltage is provided to the BCM.

Oil Pressure Sensor (1.5L Gas Engine)

The oil pressure sensor is hardwired to the PCM through VREF, signal and return circuits. The PCM provides the sensor voltage supply on the VREF circuit and monitors the voltage changes through the signal and return circuits as the oil pressure changes.

Oil Pressure Switch (Except 1.5L Gas Engine)

The EOP switch is a normally closed switch with no oil pressure and is hardwired to the PCM. The PCM provides a reference voltage to the EOP switch. When the oil pressure is within normal limits, the EOP switch opens to ground sending the reference voltage high to the PCM. When the oil pressure is low, the EOP switch closes to ground pulling the reference voltage low to the PCM.

Park Position Detect Switch

The park position detect switch is hardwired to the IPC through a single signal circuit. The park position detect switch is hardwired to a separate ground circuit through the selector lever. The IPC provides a reference voltage to the park position detect switch. When the selector lever is in PARK (P), the park position detect switch closes to ground, pulling the reference voltage low. When the selector lever is moved out of PARK (P), the park position detect switch sends the reference voltage high.

Parking Brake Position Switch

The parking brake position switch is hardwired to the BCM through a signal and ground circuit. The BCM provides a reference voltage on the signal circuit. The parking brake position switch is grounded externally through a separate circuit. When the parking brake is not applied, the parking brake position switch is open. When the parking brake is applied, the parking brake position switch closes, pulling the reference voltage low.

Seatbelt Buckle Sensor

The seatbelt buckles contain integrated sensors that are hall-effect switches. The seatbelt buckle sensors are serviced as one component with the seatbelt buckle.
