Test Description

WARNING: This page is about a different car, the 2007 Hummer H2. However, it is still accessible from the selected car via links, so may be relevant.

The numbers below refer to the step numbers on the diagnostic table.

  1. 2:  Test air suspension sensor current.
  2. 3:  Test the wiring for the overcurrent condition.
  3. 4:  Tests for the component that is creating the overcurrent.
DTC C0696

Step Action Values Yes No
Schematic Reference: Air Suspension Schematics 
1 Did you perform the Diagnostic System Check - Vehicle? - Go to Step 2  Go to Diagnostic System Check - Vehicle
2 
  1. Install a scan tool.
  2. Turn ON the ignition, with the engine OFF.
  3. With a scan tool, observe the Height Sensor Current parameter in the data list for the air suspension module.
Is the Height Sensor Current parameter within the specified range?		 3-40 mA Go to Testing for Intermittent Conditions and Poor Connections Go to Step 3 
3 
  1. Turn OFF the ignition.
  2. Disconnect the air suspension sensor - LR, air suspension sensor - RR and the air suspension pressure sensor.
  3. Turn ON the ignition, with the engine OFF.
  4. With a scan tool, observe the Height Sensor Current parameter.
Is the Height Sensor Current parameter less than the specified value?		 40 mA Go to Step 4  Go to Step 5 
4  Reconnect the air suspension sensors and air suspension pressure sensor one at a time while observing the Height Sensor Current parameter.
Is the Height Sensor Current parameter greater than the specified value when any of the components are reconnected?		 40 mA Go to Step 6  Go to Step 7 
5 Test the 5-volt reference circuit of the air suspension sensors and air suspension pressure sensor for a short to ground. Refer to Circuit Testing and Wiring Repairs .
Did you find and correct the condition?		 - Go to Step 10  Go to Step 7 
6 Inspect for poor connections at the harness connector of the air suspension sensors and air suspension pressure sensor. Refer to Circuit Testing and to Wiring Repairs .
Did you find and correct the condition?		 - Go to Step 10  Go to Step 8 
7 Inspect for poor connections at the harness connector of the air suspension module. Refer to Testing for Intermittent Conditions and Poor Connections in Wiring Systems.
Did you find and correct the condition?		 - Go to Step 10  Go to Step 9 
8 Replace the air suspension sensor or pressure sensor. Refer to Air Spring Leveling Sensor Replacement  or Valve Automatic Level Control Solenoid Replacement (Dual Compressors)  or Valve Automatic Level Control Solenoid Replacement (Single Compressor) .
Did you complete the replacement?		 - Go to Step 10  -
9
  1. Replace the air suspension module. Refer to Control Module References .
  2. Recalibrate the trim height in the air suspension module if necessary after replacement.
Did you complete the replacement?		 - Go to Step 10  -
10
  1. Use the scan tool in order to clear the DTCs.
  2. Operate the vehicle within the Conditions for Running the DTC.
Does the DTC reset?		 - Go to Step 2  System OK
