Code C1737: ELC Exhaust Solenoid Valve Short To Battery/Short Across Load

  1. Perform CVRSS system check. See CVRSS SYSTEM CHECK  . After performing CVRSS system check, go to next step.
  2. Turn ignition off. Disconnect ELC compressor assembly connector. Using DVOM, measure resistance between exhaust solenoid output circuit (White wire) and exhaust solenoid input circuit (Orange wire) of ELC compressor assembly connector (component side). See WIRING DIAGRAMS  . If resistance is 25-35 ohms, go to next step. If resistance is not 25-35 ohms, go to step 7).
  3. Disconnect 32-pin CVRSS control module connector C3. Turn ignition on, with engine off. Using DVOM, measure resistance between exhaust solenoid output circuit (White wire) of CVRSS control module harness connector C3 and ground. See WIRING DIAGRAMS  . If voltage is more than 10 volts, go to step 5). If voltage is less than 10 volts, go to next step.
  4. Check CVRSS control module connector and ELC compressor assembly connector for debris and corrosion. Reinstall/reconnect all components/connectors. Clear CVRSS codes. Wait 60 seconds. Display CVRSS codes. If Code C1737 is set as current, go to step 8). If Code C1737 is not set as current, go to step 6).
  5. Repair short to voltage in exhaust solenoid output circuit (White wire). After repairs, perform CVRSS SYSTEM CHECK  .
  6. Check for intermittent short to voltage in exhaust solenoid output circuit (White wire). Repair as necessary. After repairs, perform CVRSS SYSTEM CHECK  .
  7. Replace ELC compressor assembly and all related air lines. After repairs, perform CVRSS SYSTEM CHECK  .
  8. Turn ignition off. Replace CVRSS control module. Reinstall/reconnect all components/connectors. Install scan tool. Turn ignition on, with engine off. Calibrate NEW CVRSS control module. See CALIBRATING CVRSS CONTROL MODULE  under ADJUSTMENTS. Perform CVRSS SYSTEM CHECK  .
