Code ".7.0" Entering Testing Mode: Notes

When code ".7.0" appears on the FDP at the end of the trouble code diagnostic mode, the diagnostic mode may be exited or testing mode may be entered. The testing mode may be used to test specific items or systems for intermittent failure. If a item fails the test sequence a failure code will be recorded. A number of test choices are available and may be specifically tested by the technician. The ".7.0" code must be displayed when choosing and entering a specific test. The test selection is as follows:

• ECM Switch Tests
• ECM Data Display
• ECM Code Snapshot
• ECM Output Cycling
• ECM Output Override
• BCM Data Display
• ECC Program Override
• Cooling Fan Override
