5-12GROUP 9 SELF-DIAGNOSTIC SYSTEMOUTLINEWhen any abnormality occurs in the NEW CAPO system caused by electric parts malfunction and byopen or short circuit, the CPU controller diagnoses the problem and sends the error codes to thecluster and also stores them in the memory. The current or recorded error codes are displayed at the error display mode selected by touchingSELECT switch 2 times while pressing BUZZER STOP switch. CURRENT ERROR DISPLAYCluster displays Co : Err and makes buzzer sound itself to warn the communication error whencommunication problem caused by wire-cut or malfunction of the CPU controller occurs.Cluster displays real time error codes received from CPU controller through communication. In caseof no problem it displays CHECKEr : 00.If there are more than 2 error codes, each one can be displayed by pressing and switchrespectively. Examples :1) Communication ErrorCo : Err & Buzzer sound2) No problemCHECKEr :3) 4 Error codes(03, 06, 10, 43) display CHECKEr :RECORDED ERROR DISPLAYThe recorded error can be displayed only when the key switch is at ON position.Examples : 5 Recorded error codes(03, 06, 10, 20, 32) displayTIMEEr :DELETE ALL RECORDED ERROR CODESSelect recorded error(TIMEEr) display and press engine and select switch at the same time for2 seconds or more. Cluster display changes to TIMEEr : 00, which shows that CPU controller deletedall the recorded error codes in the memory.1.2.3.4.0 00 30 3 0 6 1 04 3StartNo changePress0 3PressPressPressPressPress Press0 3 0 6 1 02 0StartPressPressPressPressPressPress3 2PressPressNo changePress 5-136.
