Component Test Mode: Introduction

  1. This test mode is used to check the components that comprise cruise control system. By activating components one by one, and by giving control unit a response code if control unit has received a signal from component, sensor as well as wiring and connections can be checked. See COMPONENT TEST MODE CODES  table.
  2. If correct response code is not obtained, go to appropriate testing for that particular response code. If correct response codes are obtained, go to VACUUM SYSTEM CHECK .
