1. "CHECK CONTROL" message appears at ignition. Disappears shortly after.
2. Button on turn signal lever no longer triggers OBC info in cluster LCD.
3. "CHECK CONTROL - OK" appears when Check Control button activated.
4. Pushing the OBC S/R button triggers the gong.

Q: Does the CCM (Check Control Module) send a "CHECK CONTROL" message when a 1.2W cluster bulb needs replacing?

The problem occured while installing a Stellar alarm system. After installation a siren test was performed. During the test the voltage to the flashing cluster LCD seemed to drop as the cluster light dimmed. Two fuses were blown: #32 and #5. #32 seems to handle the central locking circuit, while #5 appears to take the load of the interior lighting circuit. All other fuses intact. Replacing the blown fuses revealed the cluster LCD problem.

During a bout of desperate research I happened to noticed that the realoemparts.com's parts catalog lists the 15A OBC relay fuse at 20A.
Could this be the origin of the problem? Or is a short circuit between the alarm harness and the OBC relay likely to blame?


All suggestions appreciated,
