Multimeter
Elé. 1681 Universal bornier
Switch on the forced + after ignition feed:
–with the vehicle card in the card reader,
–press and hold the Start button (longer than 5 seconds) with start-up conditions not fulfilled,
–connect the diagnostic tool and perform the required operations.
Switching off the forced + after ignition feed:
Press the Start button twice briefly (less than 3 seconds).

If the resistance is not between 3.6 and 4.4 Ω, replace the front right-hand tweeter.
Check the condition and connection of the LPN* radio navigation 8-track clear connector, component code 261,
the front right-hand tweeter connector, component code 365, and the front right-hand speaker connector,
component code 191 (bent/broken tabs, etc.).
If the connectors are faulty and if there is a repair method (see Technical Note 6015A, Repairing electrical
wiring, W iring: Precautions for repair), repair the connector(s); otherwise, replace the wiring.
Check the continuity and insulation against + 12 V, earth and between the 2 lines of the following
connections:
–connection code 34E,
–connection code 34F,
between components 261, 365 and 191.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
If the fault is still present, contact the Techline.
AFTER REPAIRCarry out another fault finding check on the system.
Clear the stored faults.
Deal with any other faults.

NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is declared present after the multimedia system has been switched on using
the on/off button.
Use the wiring diagram Technical Note for Kangoo 2.
Look for any damage to the wiring harness and check the condition and connection of the coaxial radio cable
on component 261.
Manipulate the wiring harness in order to observe a change in the fault status (present → stored).
If the connector is faulty and if there is a repair method (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the connector; otherwise, replace the wiring.
Check the resistance of the coaxial radio cable between connections 34AN and TB13 of component 886.
If the resistance is not 50 Ω ± 5 Ω, check the insulation, continuity and the absence of interference
resistance on the following connections:
–connection code TB13,
–connection code 34AN,
between component 261 and the cut-off plate at the rear.
If any connections are defective, replace the coaxial cable.
If the fault is still present, replace the aerial amplifier.
AFTER REPAIRCarry out another fault finding check on the system.
Clear the stored faults.
Deal with any other faults.
