Note. For circuit identification and wiring diagram, see WIRING DIAGRAMS article. If Powertrain Control Module (PCM) is replaced, PCM must be reprogrammed. See PROGRAMMING . After each repair procedure has been completed, reconnect all components. Perform AW4 TRANS VERIFICATION TEST under VERIFICATION TESTS to ensure system is functioning properly.
