How to read the Flash Codes
WARNING: This page is about a different car, the 2004 Pontiac Vibe. However, it is still accessible from the selected car via links, so may be relevant.
The CCM displays the DTCs by flashing the cruise control indicator lamp. Each DTC that is displayed consists of the following:
- A series of flashes which represent the tens (first) DTC digit
- A 2.5 second pause
- A series of flashes which represent the ones (second) DTC digit
For example, a FLASH DTC of 32 would be displayed as: three flashes, a 2.5 second pause, and two more flashes. Each DTC is flashed once before moving on to the next DTC. After all the DTCs are displayed, the entire DTC sequence is continually repeated until you remove the jumper from the DLC.
If there are no DTCs present, the CCM will flash the CRUISE indicator lamp continuously. This indicates that FLASH DTC diagnostics have been enabled. The CCM will continue to flash the Cruise indicator lamp until you exit from the scan tool selection or the jumper wire is removed from the DLC.
