STEPCHECK TO BE CARRIED OUTSOLUTION IF THE CHECK IS NOT OK
1Check power supply (+15)

  • With the ignition ON, check that the correct battery voltage is present between pins 4 and 8 of the 8-way Connect connector and earth.

  • Check the connector is correctly inserted in the other part.

  • Try to move it from its seat by shifting it by a small amount in all directions, holding the connector case in your fingers and the wiring in your hand. The connector should remain in place

  • Apply a moderate pulling force. The connector should remain in place

  • check whether the power supply turns off, turns on and/or vice versa (touching/not touching)

  • subject the cable to a pulling force and check cable stability (no shrinkage): apply repeated pull-push-pull cycles to the cable and check it remains immobile.
Examine the crimping:

  • Use a magnifying glass to examine the terminal criming area. The barrels must be turned symmetrically and three-stranded sections should not emerge from the criming area. The area of bare wire beneath the barrel must emerge by approximately 0.5 mm

  • Replace the 7.5A fuse F 49 located in the CPL, after identifying the cause

  • Restore the wiring if defective
2Check earthDisconnect 8-way connector A and connect an ohmmeter accross pin 8 and earth and check the resistance is lower than 1 ohmRestore the correct earth connection between pin 8 and the earth point in the right dashboard area
3Check power supply +30

  • Check that the correct battery voltage is present between pins 7 and 8 of the 8-way Connect connector and earth.

  • Check the wiring continuity

  • Replace the 15A fuse F 23 located in the CVM, after identifying the cause

  • Restore the wiring if defective
4Check fuse

  • Check the condition of the fuse located at the back of the Connect.

  • If burnt out, search for the cause of the problem and replace it.
5Check action of protection

  • Disconnect Connector 8-way connector B. Turn the Connect off and on. Check whether one of the components (CD Changer, amplifier, sound boxes, etc.) is causing the radio fuse to blow.

  • Replace defective speakers

  • Replace the defective amplifier
Op. 5570T36 AMPLIFIER FOR SPEAKER SYSTEM - R+R

  • Replace the CD Changer
Op. 5570T85

  • If none of the above steps has highlighted problems with the signals and the Connect continues not to switch on then it is defective.
