Pinpoint Test E : Height Sensor Electrical Fault Diagnostic Trouble Codes (DTCS): Notes
Refer to Vehicle Dynamic Suspension for schematic and connector information.
Normal Operation and Fault Conditions
The VDM continually monitors the height sensor circuits and sets a DTC when a circuit fault is detected. A shorted height sensor also causes the VDM to set a DTC. Refer to: Vehicle Dynamic Suspension - System Operation and Component Description .
DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| C1A03:11 | Left Front Height Sensor: Circuit Short to Ground | One or more of these Diagnostic Trouble Codes (DTCs) sets in continuous memory when the VDM detects a short to ground or an open on one or more of the height sensor circuits. |
| C1A04:11 | Right Front Height Sensor: Circuit Short to Ground | |
| C1A05:11 | Left Rear Height Sensor: Circuit Short to Ground | |
| C1A06:11 | Right Rear Height Sensor: Circuit Short to Ground | |
| C1A03:12 | Left Front Height Sensor: Circuit Short to Battery | One or more of these Diagnostic Trouble Codes (DTCs) sets in continuous memory when the VDM detects a short to battery on one or more of the height sensor circuits. |
| C1A04:12 | Right Front Height Sensor: Circuit Short to Battery | |
| C1A05:12 | Left Rear Height Sensor: Circuit Short to Battery | |
| C1A06:12 | Right Rear Height Sensor: Circuit Short to Battery | |
| U200D:11 | Control Module Output Power A: Circuit Short to Ground | One or both of these Diagnostic Trouble Codes (DTCs) sets in continuous memory when the VDM detects a short to ground one or more of the height sensor circuits. |
| U200E:11 | Control Module Output Power B: Circuit Short to Ground | |
| U200D:12 | Control Module Output Power A: Circuit Short to Battery | One or both of these Diagnostic Trouble Codes (DTCs) sets in continuous memory when the VDM detects a short to battery on one or more of the height sensor circuits. |
| U200E:12 | Control Module Output Power B: Circuit Short to Battery |
Possible Sources
- Wiring, terminals or connectors
- Height sensor
- VDM
Visual Inspection and Diagnostic Pre-checks
- Make sure the height sensor harness is routed correctly and is undamaged.
- Make sure the height sensor electrical connector is free from any corrosion or other contaminants.
