Body Control Module: Reading and Clearing Diagnostic Trouble Codes
Output
BCM OUTPUT DISPLAYS:
When troubleshooting a malfunction, the BCM output cycling can be used to determine if the output tests can be actuated regardless of the inputs and
normal program instructions. Once a test in outputs has been selected, the test will display "HI" and "LO" for three seconds in each state to indicate the
command. Actual circuit operation will depend on circuit integrity. If the test selected is not allowed under the current conditions a " =- =- " display will
result.
