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.
Trouble Code Display
After diagnostic mode is entered, all trouble codes stored in memory will be displayed. All ECM codes are prefixed with an "E" (i.e. E013, E014, etc.). Lowest numbered ECM codes will be displayed first, followed by higher numbered codes. If no ECM codes are stored, a "NO ECM CODES" message will be displayed.
Following the highest numbered ECM code or the "NO ECM CODES" message , the BCM codes will be displayed. All BCM codes are prefixed with an "B" (i.e. B013, B014, etc.) and displayed in ascending order as with ECM codes. If no BCM codes are stored, a "NO BCM CODES" message will be displayed.
Any ECM or BCM will also be accompanied by the words "CURRENT" or "HISTORY". A "HISTORY" code indicates an intermittent failure, a "CURRENT" code indicates that fault still exists (current failure). If "LO" button on CCDIC is pressed, at any time DURING display of trouble codes, display of trouble codes will be by-passed.
