Code C1710, C1715, C1720 & C1725: Damper Actuator Short Circuit 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 damper actuator connector. Using DVOM, measure resistance between terminals of damper actuator connector (component side). If resistance is 9.5-15.5 ohms, go to next step. If resistance is not 9.5-15.5 ohms, go to step  7 .
  3. Turn ignition on, with engine off. Using DVOM, measure voltage at damper ground circuit (LF=LT GRN, RF=BRN, LR=RED/BLK, RR=PPL) of damper actuator connector (component side). See WIRING DIAGRAMS  . If voltage is 10 volts, go to step  7 . If voltage is not 10 volts, go to next step.
  4. Turn ignition off. Disconnect 32-pin CVRSS control module connector C1. Turn ignition on, with engine off. Using DVOM, measure voltage at damper control circuit (LF=RED, RF=WHT/BLK, LR=RED, RR=YEL) of CVRSS control module harness connector C1. If voltage is 10 volts, go to step  8 . If voltage is not 10 volts, go to next step.
  5. Check continuity between damper control circuit (LF=RED, RF=WHT/BLK, LR=RED, RR=YEL) and damper ground circuit (LF=LT GRN, RF=BRN, LR=RED/BLK, RR=PPL) of CVRSS control module harness connector C1. See WIRING DIAGRAMS  . Repair as necessary. If circuits are okay, go to next step.
  6. Check for intermittents in damper actuator circuits. Turn ignition off. Reinstall/reconnect all components/connectors. Turn ignition on, with engine off. Clear codes, and then wait 90 seconds. Display codes. If Code C1710, C1715, C1720 or C1725 is set, go to step  9 . If Code C1710, C1715, C1720 or C1725 is not set, see NOTES ON INTERMITTENTS  under DIAGNOSIS & TESTING.
  7. Replace damper actuator.
  8. Repair short to voltage in damper control circuit (LF=RED, RF=WHT/BLK, LR=RED, RR=YEL).
  9. 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.
