• Turn ignition switch on, with the scan tool, view and erase stored DTCs in the Automated Manual Transaxle
(AMT) control module.
• Start the engine and warm it to normal operating temperature.
• Drive the vehicle up to 10 km/h or more.
• With the scan tool, select view DTC and data stream.
• If the DTC is detected, the DTC condition is current. Go to Diagnostic Procedure - Step 1.
• If the DTC is not detected, the DTC condition is intermittent (See Diagnostic Help and Intermittent DTC Trou-
bleshooting in Section 08 Transaxle for more information).
NOTE :
• If DTC P0720 or P0805 are also present, diagnose and repair them before continuing with this test.
