Diagnostic Fault Information
Circuit/System Description
The engine control module (ECM) supplies voltage to the fuel pump control module when the ECM detects that the ignition is on. The voltage from
the ECM to the fuel pump control module remains active for 2 seconds, unless the engine is in crank or run. While this voltage is being received,
the fuel pump control module supplies a varying voltage to the fuel tank pump module in order to maintain the desired fuel rail pressure.
Conditions for Running the DTC

Circuit/System Description
The passenger presence system (PPS) uses a silicone filled sensor pad located underneath the passenger seat foam cushion and is connected by a

ratio to the calculated gear ratio for each commanded gear.
Conditions for Running the DTC
P2714
* DTCs P0716, P0717, P0722, P0723, P1825, or P1915 are not set.
* The transmission input shaft speed is greater than 60 RPM.
* 2-6 clutch is commanded ON.
P2715
* DTCs P0716, P0717, P0722, P0723, P1825, or P1915 are not set.
* The transmission output shaft speed is greater than 200 RPM.
* 2-6 clutch is commanded OFF.
Conditions for Setting the DTC
P2714
The TCM detects an incorrect on-coming clutch gear ratio, or flare, when the 2-6 clutch is commanded ON for 0.5 seconds and the transmission
input shaft speed is greater than 75 RPM from the anticipated input shaft speed.

Circuit/System Description
The engine control module (ECM) supplies voltage to the fuel pump control module when the ECM detects that the ignition is on. The voltage from
the ECM to the fuel pump control module remains active for 2 seconds, unless the engine is in crank or run. While this voltage is being received,
the fuel pump control module supplies a varying voltage to the fuel tank pump module in order to maintain the desired fuel rail pressure.

瀚慖f greater than the specified range, test the circuit for a short to voltage
7. Test for less than 1 ohm between the PPS module signal circuit terminal 4(X88+HP2/Z88+HP2) or terminal 6 (-HP2/Z75+HP2) and the
passenger seat belt tension sensor terminal C X2.
瀚慖f greater than the specified range, test the signal circuit for an open/high resistance. If the circuit tests normal, replace the PPS module.
8. If all circuits test normal, replace the passenger seat belt buckle which includes the seat belt tension sensor.

Diagnostic Fault Information
Circuit/System Description
The passenger presence system (PPS) uses a silicone filled sensor pad located underneath the passenger seat foam cushion and is connected by a
hose clamp to a pressure sensor. The weight of the occupant sitting in the front passenger seat is measured as a pressure change within the bladder
by the pressure sensor. The pressure sensor is a 3-wire sensor consisting of a power, ground, and signal circuit. The PPS continually monitors itself
and if a fault in this circuit occurs, a DTC will set. When the sensing and diagnostic module (SDM) detects this DTC within the PPS, it will notify
the customer of the enable/disable status by illuminating the OFF indicator on the PASSENGER AIR BAG ON/OFF indicators. Then the PPS will
communicate to the SDM through serial data communications that a PPS fault is present. The SDM will then suppress the deployment of the
