Capt'n Rob Posted October 22, 2008 Report Share Posted October 22, 2008 Also after looking up the C1710 and c1715 code, could it be a short of some kind? If so where do I start to trouble shooting that?

DTC C1715 RF Damper Actuator Short CKT to Battery DTC C1710 LF Damper Actuator Short CKT to Battery These codes are suspension related and have nothing to do with the AC/HEAT but someone will have knowledge of these codes.

Bruce Nunnally Posted October 22, 2008 Report Share Posted October 22, 2008 DTC C1715 RF Damper Actuator Short CKT to Battery The RF damper actuator is driven by the CVRSS module via a method known as Pulse-Width Modulation (PWM). Battery voltage is modulated (switched on and off) at a high frequency (2.0 kHz), thus controlling the amount of current delivered to the actuator. By controlling the amount of current to the actuator, the CVRSS module can then control the damping force in the damper. A higher level of damping force is achieved by providing correspondingly higher current levels, relating to higher percentages of PWM duty cycle. The default damper state (with no battery voltage, and thus no current, provided to the attached actuator) is one that provides a minimum damping force. Conditions for Setting the DTC The DTC is set when the CVRSS module measures a feedback voltage greater than a preset fault threshold during a damper diagnostic test procedure. The DTC is set when the CVRSS module performs a test procedure on each damper actuator approximately every 16 seconds. During this test procedure the damper actuator is briefly energized (ON-state test) and de-energized (OFF-state test). If, twice consecutively, the feedback voltage during the ON-state test is above the fault threshold, the corresponding DTC is set. The DTC turns HISTORY when the CVRSS module no longer senses an short circuit condition to battery voltage on the damper low-side drive. Action Taken When the DTC Sets * The RF damper actuator will be disabled by commanding 0 percent PWM duty cycle. The RF corner of the vehicle will be soft. * The SERVICE RIDE CONTROL message will be displayed. Conditions for Clearing the MIL/DTC * Use the scan tool. * Use the On-Board diagnostic CLEAR RSS CODES feature.

JimD Posted October 22, 2008 Report Share Posted October 22, 2008 It would be a long odds event to have both front solenoid coils go open at the same time, but you should eliminate the possibility. Follow the wire harness from the strut to the connection with the car harness. Pull the connection apart and measure the resistance of the solenoid coil across the two pins; you should see something like 12 Ohms, plus or minus 3 Ohms. You will find the connector for the strut wire harness inside the engine cradle. Jim Drive your car. Use your cell phone. CHOOSE ONE ! Link to comment Share on other sites More sharing options...
