Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.

After the "Service Mode" is entered, any trouble codes stored in the computer will be displayed. ECM codes will be displayed first. If no ECM codes are stored, the IPC will display "NO ECM CODES". All ECM codes will be prefixed by an "E" (i.e. EO13).
When all ECM codes have been displayed, BCM codes will be displayed. BCM codes mainly deal with body control functions, with climate control being one of its main features. BCM codes are prefixed with an "B" (i.e. B110). BCM codes can also be accompanied by "Current", indicating that the fault still exists. If no BCM codes exist, "NO BCM CODES" message will be displayed.
Both ECM and BCM codes are displayed in 2 second intervals starting at the lowest numbered code and ending at the highest. If the "LO" fan button is pressed anytime during the display of ECM and BCM codes, the display of codes will be by-passed. If at any time the "BI-LEVEL" button is pressed, the BCM will exit the "Service Mode" and go back to normal vehicle operation.
