1. If the cruise ON/OFF switch or CRUISE BRAKE switch has failed, you cannot enter the switch test sequence.
2. After .7.0 is displayed on the Fuel Data Center (FDC), the PCM Switch Test can be initiated by depressing the brake pedal. When the brake pedal has been depressed the FDC will display E.7.0.
3. At this time the HI and LO buttons on the Electronic Climate Control (ECC) panel can be used to select the specific switch test.
4. When a specific test has been selected and that switch activated, the display will alternately display the code for that test and E.0.0 to confirm the switch is working.
