(a) Check the DTC for Vehicle Stability Control System Reading and Clearing Diagnostic Trouble Codes.





B -- GO TO DTC CHART Vehicle Stability Control System
A -- Continue to next step.

2. CHECK HARNESS AND CONNECTOR (SKID CONTROL ECU - ECM)

(a) Disconnect the A27 connector from the ECM.





(b) Disconnect the A19 connector from the ECU.

(c) Measure the resistance according to the value(s) in the table below.

Standard Resistance:





(d) Reconnect the ECM and ECU connector.

NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.

3. REPLACE VSC ACTUATOR ASSEMBLY

(a) Temporarily replace the VSC actuator assembly with a new or normally functioning one Removal.

NEXT -- Continue to next step.

4. CLEAR DTC

(a) Clear the DTC Cruise Control System.

NEXT -- Continue to next step.

5. CHECK FOR DTC
