Pinpoint Tests

PINPOINT TEST A: U3003:16

Refer to Wiring Diagrams Cell 41 for schematic and connector information.

Normal Operation and Fault Conditions

The VDM requires an operating voltage that is between 9 and 16 volts. The VDM receives this voltage from the BCMC which has an internal FET that is switched ON and OFF. The VDM has a single ground circuit. Excessive resistance or an open in one or more of these circuits, a discharged battery or an inoperative charging system results in the VDM setting a DTC . After setting the DTC the VDM deactivates the dynamic suspension system resulting in a firm/harsh suspension feel and send a message to the IPC to display a dynamic suspension system warning message.

DTC Fault Trigger Conditions

DTC	Description	Fault Trigger Condition
VDM U3003:16	Battery Voltage: Circuit Voltage Below Threshold	This DTC sets in continuous memory and on-demand if the voltage supplied to the VDM falls below 9 volts for more than 500 milliseconds.

PINPOINT TEST C: P1758:19

Refer to Wiring Diagrams Cell 41 for schematic and connector information.

Normal Operation and Fault Conditions

Using input from the height sensors and FD-CAN messages, the VDM provides a varying current to the damper solenoid valves. The VDM is programmed with an upper limit for this current. One or more of the height sensors failing internally and damage or modifications to the vehicle suspension may cause this DTC to set. After setting the DTC the VDM deactivates the dynamic suspension system resulting in a firm/harsh suspension feel and send a message to the IPC to display a dynamic suspension system warning message.

DTC Fault Trigger Conditions

DTC	Description	Fault Trigger Condition
VDM P1758:19	Pressure Solenoid Control System Incorrect Current: Circuit Current Above Threshold	This DTC sets in continuous memory if one or more of the damper solenoids requests a current greater than or equal to a preset maximum current for a given duration, 3 or more times during the same ignition cycle. The maximum current threshold and duration is 1.9 amps for 2 minutes.

Possible Sources

Height sensor(s) incorrectly installed
Height sensor(s) faulted
Height sensor(s) damaged

PINPOINT TEST D: LEFT FRONT DAMPER SOLENOID ELECTRICAL FAULTS

Refer to Wiring Diagrams Cell 41 for schematic and connector information.

Normal Operation and Fault Conditions

The VDM sends a variable voltage to the damper solenoids based on sensor input and FD-CAN messages. The VDM continually monitors the damper solenoid circuits and sets a DTC when a circuit fault is detected. A shorted or open damper solenoid also causes the VDM to set a DTC . After setting the DTC the VDM deactivates the dynamic suspension system resulting in a firm/harsh suspension feel and send a message to the IPC to display a dynamic suspension system warning message.
