Red lighting is off on the left and right but good in the center.

is the driver left side as in USA? (LHD or RHD)?
educated means too we read the service manual (SM)
and the page on rear lamps. Schematics, or we just fiddle about and guess.

fuses all good, we check them all.
the problem #1 is on BCM cars, no 2 BCM work the same
so again the SM comes to our rescue.
BCM is body brain and runs all lamp, in odd ways, you don't know yet.
answering for only USA cars, LHD.
brake lamps are rear amps 2 or 3 total

that socket burnup (where) is signs of dead shorted lamp.
needs new lamp first and new socket 2nd.
the IPS runs all 3 rear stop lamps left, center and right.
facts, Schematic on my screen
all 3 lamps use the same single wire to glow. branks
but not ground
left uses GF04 ground wire to body.
GF04 ground runs the other 2 lamps.
so the only failure here is left lamp

• the lamp bad
• the wire bad (or socket0
• or the ground bad GF04

2 man job, step brake, 2nd man meter in hand.
a voltmeter tells you which one is bad.
step on brake pedal 12vdc here, all 3 on that 1 wire.
ground reads 0v.
yes ,yes, then lamp is bad.


meter black test wire must be to perfect metal ground for tests.
max ground volts is 0.5vdc max.but 0 is goal.
the lamp shorted I guess and burned up parts related.

hello

Although you posted that a few years ago, I'll still give my 25¢

From top left to right: red pin, blank blank Middle left to right: black, white, blue Bottom left to right: orange, yellow, purple
Top left pin (red) is positive and 1st left pin in middle (black) is negative. Straight 120v, but I don't know how to vary the speed by utilizing the other pins

Good lord there are fuses everywhere in that truck if I remember right, you'd have been better off asking about the problem I think.. try here
http://www.jeep4x4center.com/knowledge-base/index.htm#service
find your truck, pull up the PDF then on your keyboard hit the find box (F3?) punch in "fuse" and run down the list...

This is tough to say without being their.. But lets try...You need to hook up the power cord correctly before doing any other diagnostics...On the dryers terminal block you should have a black on one side, white in the center, and red on the other side THE POWER CORD WIRES HAVE TO BE HOOKED UP THIS WAY. when checking voltage at the back of unit make sure its 120 volts from center to right side , and 120 volts from center to left side after this is correct we can diagnosis from their if its not working right.......

did you check the six 3.5 pico fuses that are next to the ICs? They will often be open ( blown) when the ICs fail. Also check the two 5 amp IC protectors on the G board as those protect the two ICs so its possible they have blown also a 5 amp pico can be substituted for the two IC protectors.

being that youre able to control adjustments in the center of the screen your ICs have to be good, you will need a tech for that repair as its a problem within the DCU , convergence yokes or faulty component within the convergence power supply other than the ICs.

Check the resistors in the red convergence circuit right next to the Ics you will need to lift one side of the resistor out of circuit to acurately check them but usually one or two resistors will be opened when the ICs go out

i have the same problem
