CCS4 - Checking Cruise Control On/Off Function

  1. Connect diagnostic readout box to engine harness connector. Put system in Sensor Test Mode 09. Move cruise control on/off switch to "ON" position. Connect jumper wire between cavities No. 2 and 15 of logic module Black connector (Blue on turbo). If readout box display is "blank", ensure terminal in connector cavity No. 15 is not damaged, causing a poor connection. If terminal is okay, replace logic module.
