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 BCM. The VDM has a single ground circuit. Excessive resistance or an open in one or more of these circuits, a discharged battery or a inoperative charging system results in the VDM setting a DTC.

DTC Fault Trigger Conditions

Possible Sources

• Fuses
• Wiring, terminals or connectors
• VDM

Visual Inspection and Pre-checks

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 BCM. The VDM has a single ground circuit. Excessive resistance or an open in one or more of these circuits, a discharged battery or a inoperative charging system results in the VDM setting a DTC.

An overcharging condition in the charging system results in the VDM setting a DTC. This DTC may also set in the VDM due to battery charging or vehicle jump starting events.

DTC Fault Trigger Conditions

Possible Sources

• Charging system concern
• VDM

• Using a diagnostic scan tool, retrieve all Continuous Memory Diagnostic Trouble Codes (CMDTCs).

• Turn off all interior lights, exterior lights and accessories.

• NOTE: Do not allow the engine speed to increase above 2,000 RPM while performing this step or the generator may self-excite and result in default charging system output voltage. If engine speed goes above 2,000 RPM, turn the engine off and restart the engine before performing this step. Start and run the engine at approximately 1,500 RPM for 3 minutes while monitoring the battery voltage.

Normal Operation and Fault Conditions

Using input from the height sensors and HS-CAN2 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.

DTC Fault Trigger Conditions

Possible Sources

• Height sensor(s) incorrectly installed
• Height sensor(s) faulted
• VDM calibration

• Using a diagnostic scan tool, carry out the VDM self-test.

• With the transmission in NEUTRAL, position the vehicle on a hoist.
  REFER to: Jacking and Lifting - Overview (100-02 Jacking and Lifting, Description and Operation).
  

• Inspect all 4 height sensors, make sure they are undamaged and correctly installed.
  REFER to: Front Suspension Height Sensor (204-05 Vehicle Dynamic Suspension, Removal and Installation).
  REFER to: Rear Suspension Height Sensor (204-05 Vehicle Dynamic Suspension, Removal and Installation).
  

• Using a diagnostic scan tool, carry out the Ride Height Calibration routine without passengers or cargo in the vehicle.

• Test drive the vehicle above 8 km/h (5 mph) on a smooth surface for at least 3 minutes and use a diagnostic scan tool to record the following Parameter Identifications (PIDs):
  • Left Front Damper Current (LF_DAMP_CUR)
  • Right Front Damper Current (RF_DAMP_CUR)
  • Left Rear Damper Current (LR_DAMP_CUR)
  • Right Rear Damper Current (RR_DAMP_CUR)

  • Right Front Height Sensor Voltage (RF_Hght_Sens)
  • Left Rear Height Sensor Voltage (LR_Hght_Sens)
  • Right Rear Height Sensor Voltage (RR_Hght_Sens)

Normal Operation and Fault Conditions

The VDM sends a variable voltage to the damper solenoids based on sensor input and HS-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.

DTC Fault Trigger Conditions

Normal Operation and Fault Conditions

With the ignition ON, the PCM sends messages to the GWM over the HS-CAN1. The GWM sends these messages to the VDM over the HS-CAN2. If the VDM does not receive these messages within a certain time frame, the module sets Diagnostic Trouble Codes (DTCs). For information on the messages sent to the VDM by the PCM, go to the Network Message Chart. REFER to: Vehicle Dynamic Suspension - Overview (204-05 Vehicle Dynamic Suspension, Description and Operation).

NOTE: If new modules were installed prior to the DTC being set, the module configuration can be incorrectly set during the PMI or the PMI may not have been carried out.

• Check the vehicle service history for recent service actions related to the ABS module or VDM. If recent service history is found:
  • verify the correct replacement module was installed.
    • HVBOM may be used to verify correct part fitment.
  • verify the configuration of replacement module was correct.
    • re-configure the module using as-built data if prior configuration is suspect.
  • verify the module was not obtained from a like vehicle and installed into customer vehicle.
    • return the swapped module to source vehicle and obtain new replacement module.

• Operate the system and determine if the observable symptom is still present.

• Using a diagnostic scan tool, carry out the self-test for all modules.

Normal Operation and Fault Conditions

With the ignition ON, the EPAS sends messages to the GWM over the HS-CAN2. The GWM sends these messages to the VDM over the HS-CAN2. If the VDM does not receive these messages within a certain time frame, the module sets Diagnostic Trouble Codes (DTCs). For information on the messages sent to the VDM by the EPAS, go to the Network Message Chart. REFER to: Vehicle Dynamic Suspension - Overview (204-05 Vehicle Dynamic Suspension, Description and Operation).
