P0593-SPEED CONTROL SWITCH 2 CIRCUIT HIGH (CONTINUED) 2. SPEED CONTROL SWITCHES Disconnect and remove the Speed Control Switches from the steering wheel. Measure the resistance across each Speed Control Switch. Monitor the ohmmeter while pressing each function button on each switch. The following resistance specs are taken between terminals (V38) S/C Switch No.2 Signal and (V937) S/C Switch Not pressing any switch - 20.5 kohms On/Off - 8.87 kohms Set - 0.825 kohms Coast - 0.47 kohms Cancel - 3.92 kohms Resume/Accel - 1.87 kohms Does the function on the Speed Control Switches have the correct resistance value? Yes >> Go To 3 No >> Replace the Speed Control Switch that had the incorrect resistance value. Perform the POWERTRAIN VERIFICATION TEST. (Refer to 9 - ENGINE - STANDARD PROCEDURE) 3. CLOCKSPRING Disconnect the upper and lower Clockspring harness connector per Measure the resistance of the (V937) Switch Return circuit between Measure the resistance of the (V38) S/C Switch No.2 Signal circuit Was the resistance above 5.0 ohms for either circuit? Yes >> Replace the clockspring. Perform the POWERTRAIN VERIFICATION TEST. (Refer No >> Go To 4 9 - 674 ENGINE - ELECTRICAL DIAGNOSTICS - 3.7L/4.7L/5.7L DR/DH |
