Circuit/System Testing

Test A

1. Ignition OFF, disconnect the connector at the appropriate Q37 Shock Absorber Actuator:
   • DTC C1034 = Q37LF Shock Absorber Actuator - Left Front
   • DTC C1035 = Q37LR Shock Absorber Actuator - Left Rear
   • DTC C1036 = Q37RF Shock Absorber Actuator - Right Front
   • DTC C1037 = Q37RR Shock Absorber Actuator - Right Rear
2. Connect a test lamp between the control circuits terminal 1 and terminal 2, ignition ON.
3. Verify the test lamp illuminates.
   • If the test lamp does not illuminate 
   1. Test the appropriate circuits for a short to ground:
      • DTC C1034 = Circuit 1107, 1113
      • DTC C1035 = Circuit 1114, 1117
      • DTC C1036 = Circuit 1116, 1115
      • DTC C1037 = Circuit 1118, 1119
      • If a short to ground is found, repair the fault on the circuit.
      • Go to next step: If a short to ground is not found.
   2. Test the appropriate circuits for an open/high resistance:
      • DTC C1034 = Circuit 1107, 1113
      • DTC C1035 = Circuit 1114, 1117
      • DTC C1036 = Circuit 1116, 1115
      • DTC C1037 = Circuit 1118, 1119
      • If an open/high resistance is found, repair the fault on the circuit.
      • Go to next step: If an open/high resistance is not found.
   3. Test the appropriate circuits for a short to voltage:
      • DTC C1034 = Circuit 1107, 1113
      • DTC C1035 = Circuit 1114, 1117
      • DTC C1036 = Circuit 1116, 1115
      • DTC C1037 = Circuit 1118, 1119
      • If a short to voltage is found, repair the fault on the circuit.
      • Go to next step: If a short to voltage is not found.
   4. Replace the K19 Suspension Control Module.
   • Go to next step: If the test illuminates 
4. Test or replace the appropriate Q37 Shock Absorber Actuator.

Test B

1. Ignition OFF, disconnect the connector at each of the Q37 Shock Absorber Actuators.
2. Disconnect the connector at the K19 Suspension Control Module.
3. Test the following circuits for a short to ground:
   • Circuit 1107
   • Circuit 1113
   • Circuit 1114
   • Circuit 1115
   • Circuit 1116
   • Circuit 1117
   • Circuit 1118
   • Circuit 1119
   • If a short to ground is found, repair the fault on the circuit. 
   • Go to next step: If a short to ground is not found 
4. Test for 2 - 4 Ω between each Q37 Shock Absorber Actuator terminals 1 and 2.
   • If not within the specified range 

     Replace the appropriate Q37 Shock Absorber Actuator.

   • Go to next step: If within the specified range 

     Go to next step: Replace the K19 Suspension Control Module.
