Test E: Shock Actuator Circuit Failure

  1. Check Sensor Connections

    Disconnect and inspect shock actuator connectors for corrosion, damaged pins or wiring. Repair or replace as necessary. Go to next step.

  2. Check Actuator Resistance

    Check resistance across shock actuator solenoid terminals. If resistance is 15-21 ohms, go to next step. If resistance is not 15-21 ohms, replace shock assembly. Repeat self test. See SELF TEST  .

  3. Check For Open Circuit 57 (Black)

    Check resistance between shock actuator circuit 57 (Black) and ground. If resistance is more than 3 ohms, repair open in circuit 57 (Black). If resistance is 3 ohms or less, go to next step.

  4. Check For Short To Power

    Disconnect SARC connectors. Check voltage between circuit 840 (White/Black), circuit 841 (White/Red), circuit 842 (White/Orange), circuit 843 (White) and ground. See Figure . If voltage exists, repair short to power. Repeat self test. See SELF TEST  . If no voltage exists, go to next step.

  5. Check For Open Circuit

    Check continuity of circuit 840 (White/Black), circuit 841 (White/Red), circuit 842 (White/Orange) and circuit 843 (White) between SARC module connector and shock actuator connector.If resistance on each circuit is 3 ohms or less, go to next step. If resistance is more than 3 ohms, repair affected circuit. Perform self test.
