Question about Kenwood KDC-MP435U CD Player

1 Answer

Illumination v. Dimmer

When I installed my unit in my F150, I found that the truck had two light wires - 1 for illumination and 1 for dimmer. But, my Metra BB-1771 wiring harness only had one wire for lighting. The plastic wire cover said "ILLUM" and the stick-on tab on the end said "DIM". I hooked the harness wire up to the truck dimmer wire. The display now dims when I turn on my lights. But, now I've noticed that the the clock does not display when the unit is turned off (don't turn it off much, so it took a while to notice it). Don't know what it would have done if I had connected to the Illumination wire instead. Is this typical of the KDC-MP435U? Should I have connected to the truck illumination wire instead?

    My problem with the clock is that if the unit is off, even while the car is running, the clock does not display. I can understand it not displaying if the car is turned off, but is it normal for this model to not show any display when the unit is off and the car is running?

Good day,

The illum wire goes directly to the headlight switch and tells it when to light up, where as the dimmer wire is variable meaning it would dim up or down with your dash light control. Dimmmer is usually only need on factory radio's and not aftermarket. I suggest wiring only to the illuum lead and do not connect dim. Also about the clock make sure your red and yellow wires are not crossed, yellow is a constant hot and red is only hot when the ignition is on, so if they are backwards the radio would loose it's memory when you turn the key off.

Hope this helps

What is the fuse number for the dashboard lights on a 2007 Ford Focus 3 door hatchback?


Principles of Operation
The instrument cluster and panel illumination consists of dimmable and non-dimmable illumination components. The dimmable illumination is controlled by the instrument panel dimmer switch, which allows the brightness level of the backlights to be adjusted to the customer preferences. With the parking lamps ON, the instrument panel dimmer switch uses electronic circuitry to provide a variable pulse width modulated (PWM) output to the instrument panel and all applicable switches depending on the driver-controlled level of intensity. The headlamp switch backlighting consists of 2 constantly illuminated LED bulbs that are powered by separate circuits. Battery voltage is supplied to the first bulb when the ignition switch is in the RUN position. Battery voltage is supplied to the second bulb with the parking lamps ON. The non-dimmable illumination allows for full intensity dependant on the ignition switch position.

Inspection and Verification
  1. Verify the customer concern.
  1. Visually inspect for obvious signs of mechanical or electrical damage.


Visual Inspection Chart Mechanical Electrical
  • Headlamp switch
  • Instrument panel dimmer switch
  • Circuitry
  • Connector(s)

I have an 06 ford explorer the instrument cluster lights and radio lights don't work


Are these the lights you are talking about ?
Instrument Cluster and Panel Illumination The instrument cluster and panel illumination is used to provide backlighting to the instrument panel, switches, and control components when the headlamp switch is in either the PARKING LAMPS ON or HEADLAMPS ON position. The level of intensity is adjustable by rotating the instrument panel dimmer switch either up to increase intensity or down to decrease intensity.
Fixed Backlighting When the accessory delay relay is energized, switched voltage is supplied to the non-dimmable components and switches.
Dimmable Backlighting When the parking lamps or the headlamps are in the ON position the smart junction box (SJB) monitors the input from the instrument panel dimmer switch. The SJB sends a pulse-width modulated (PWM) voltage to the dimmable components and switches based on input received from the instrument panel dimmer switch. The SJB also sends a message over the controller area network (CAN) to the audio unit, and the instrument cluster to indicate the backlighting intensity level.
If you don't know about PWM an smart junction box your better off taking your vehicle to a quailified repair shop ! You don't the diagnostic tools or technical information . May have DTC'S - diagnostic trouble codes stored in the SJB (computer ). Do you know where SJB is located ?
Visual Inspection Chart Electrical
  • Smart junction box (SJB) fuse 23 (15A)
  • Bulb(s)
  • Circuitry
  • Connectors
  • Illumination source(s)
  • Auxiliary climate control switches (if equipped)
  • Door lock control switches
  • Window control switches
  • Headlamp switch
  • Dual electronic automatic temperature control (DEATC) module
  • Audio unit
  • SJB
  • Instrument cluster

  1. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
  1. If the cause is not visually evident, connect the diagnostic tool to the data link connector (DLC) and select the vehicle to be tested from the diagnostic tool menu. If the diagnostic tool does not communicate with the vehicle:
  • check that the program card is correctly installed.
  • check the connections to the vehicle.
  • check the ignition switch position.
  1. If the diagnostic tool still does not communicate with the vehicle, refer to the diagnostic tool operating manual.
  1. Carry out the diagnostic tool data link test. If the diagnostic tool responds with:
  • CAN circuits fault; all electronic control units no response/not equipped, refer to Section 418-00 .
  • No response/not equipped for SJB, refer to Section 419-10 .
  • System passed, retrieve and record the continuous diagnostic trouble codes (DTCs), erase the continuous DTCs, and carry out the self-test diagnostics for the SJB.
  1. If the DTCs retrieved are related to the concern, go to the Smart Junction Box (SJB) Diagnostic Trouble Code (DTC) Index.
  1. If no DTCs related to the concern are retrieved, GO to Symptom Chart .
    • The control illumination is inoperative
    • Fuse
    • Smart junction box (SJB)
    • Go To Pinpoint Test A .
    • The instrument cluster illumination is inoperative
    • Instrument cluster
    • CHECK the audio unit illumination for correct operation.
      • If the audio unit illumination operates correctly, INSTALL a new instrument cluster. REFER to Section 413-01 . TEST the system for normal operation.
      • If the audio unit illumination does not operate correctly, REFER to Section 418-00 to continue diagnosis of the communications network.
    • The audio unit illumination is inoperative
    • Audio unit
    • CHECK the instrument cluster illumination for correct operation.
      • If the instrument cluster illumination operates correctly, REMOVE the audio unit. REFER to Section 415-01 . SEND it to an authorized repair facility. TEST the system for normal operation after the repair.
      • If the instrument cluster illumination does not operate correctly, REFER to Section 418-00 to continue diagnosis of the communications network.

When I turn headlights on none of the dash lights come on,when sliding on dimer switch nothing happeneds, when putting power to the back of dash lights, lights will come on with tester


DId you just install something, if you install something like a radio, you probably or someone probably messes with a the illumination wire and too much power is going there, first find the wire, then change the fuse..........

R&R and dimmer wire color? VRCD400-SDU


Dimmer wire for your car should be RED wire in wire harness, illumination is RED/BLACK. check to see which wire works with a light tester. you should never use the dimmer wire with an aftermarket radio, only the illumination wire. Dimmer wire has fluctuating voltage when you move the dimmer up and down. Illumination wire is a contant voltage of +12V and aftermarket radios use this set up.

Aftermarket double din install having problems with int. dash lights,locks


I had soved my problem... That was stupid.. The cause is that I tried to connect the (illumination +) and the (illumination -) wires togetter on the dimmer wire of my double din unit. That make a short cut and blow the litening fuse (fuse 13 on passenger side fuse panel). I replaced correctly the wiring, keeping the (illumination +) wire unused. That solve my problem but, however I get back my dash illumination, I can't adjust the lightning level... I thing I have a problem with the level switch.. It don't matter to me but if you get the same problem and solve it, please tell me your solution.

What to hook the dimmer wire & illumination wire to


Those lower end Sony models dont use a dimmer or illumination. The display is constantly one brightness level.
Simply terminate or tape off those wires from the plug.
