Showcase of Instrument cluster and cruise control self-test using diagnostic software on Honda CR-V 2.2 I-CTDI 140HP 2007 RE6. There is also a manual enter mode but that doesn`t work on my car Entering the self-diagnostic function (manual method) NOTE: This procedure takes precise timing. Ill may take several tries to enter the self-diagnosis mode. Before doing the self-diagnostic function,check the No. 10 (7.5 A) fuse in the under-dash fuse/relay box and the No. 23 (10 A) fuse in the under-hood fuse/relay box. 1. Push and hold the SEL/RESET switch button. 2. Turn the headlights ON. 3. Turn the ignition switch ON (II). 4. Within 5 sec.,turn the headlights OFF, then ON and OFF again. 5. Within 5 sec.,release the SEL/RESET switch button, and then push and release the button three times repeatedly. Switch Input Check At the initial stage of the self-diagnostic function,the beep sounds intermittently,the beeper sounds continuously when any of the following switch inputs are switched from OFF to ON: Cruise control main, SET, RESUME, CANCEL switches, SEL/RESET switch,parking brake switch,and VSA OFF switch. The illumination volume (+) and (-) switch (dash lights brightness controller) can be tested by turning on the headlights and verifying that the dash lights brightness changes as you turn the switch from full dim to full bright.
