P0585-SPEED CONTROL SWITCH 1/2 CORRELATION (CONTINUED) 3. SPEED CONTROL RESUME/ACCEL SWITCH With the scan tool, monitor the Speed Control Switch voltage. Disconnect the Speed Control Resume/Accel Switch harness connector. Did the voltage change to above 4.8 volts? Yes >> Replace the Speed Control Resume/Accel Switch. Perform the POWERTRAIN VERIFICATION TEST. (Refer to 9 - ENGINE - STANDARD PROCEDURE) No >> Go To 4 4. SPEED CONTROL SWITCHES Turn the ignition off. Remove and disconnect the Speed Control Switches from the steering wheel per Service Information. 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 (V372) S/C Switch No.2 Signal and (V397) 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 The following resistance specs are taken between terminals (V371) S/C Switch No.1 Signal and (V397) S/C Switch Not pressing any switch - 20.5 kohms On/Off - 0.47 kohms Set - 5.49 kohms Coast - 2.94 kohms Cancel - 1.24 kohms Resume/Accel - 15.4 kohms Does the function on the Speed Control Switches have the correct resistance value? Yes >> Go To 5 No >> Replace the Speed Control Switch that had the incorrect resistance value. Perform the POWERTRAIN VERIFICATION TEST.
