Gas engine not the Diesel right, none told. diesel trans is different for reverse gear.
the lamps go to the BCM
USA car or not sorry they are NOT all the same. world wide.
is there a problem, ? or adding missing trailer option? now to add it?
no job told so I work blind? if the fail, now say so and there are many causes and the MTIP brain.
guess MK49 jeeps based off
Mitsubishi GS platform yes one odd car.
i have the PDF on this car real from jeep so will post that next
218 schematic pages in fact.
gas
the transmission TRS (prndl) switch tells TCM reverse
it uses the can-bus network to tell PCM and TIPM to turn on backup lamps. The cluster gets the same signal for REVERSE.
do you have AWD and or Autostick, yes complex options and all mater for wiring.
page 179 found it.

The TIPM module drives this wire, LT/LG

Usually the fuse schematic and what they control is on the inside of the fusebox covers - one is under the left dash and other is under the hood on the same side. If you have an owners manual, you'll find all this in there.

GAS ENGINES
Radiator fan operation is controlled by the Total Integrated Power Module (TIPM) with inputs from the Powertrain Control Module (PDC). Inputs for coolant temperature and vehicle speed are sent to the the Powertrain Control Module (PCM) (1). This information is then sent via the communication bus to the TIPM which turns on the radiator fans.
Refer to Radiator Fan Operation Chart for fan operation specifications. For fan circuit wiring diagrams, refer to WIRING DIAGRAMS.
If the cooling fan is inoperative or a Diagnostic Trouble Code (DTC) related to fan control has been set, (Refer to 28 - DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Diagnosis and Testing) for diagnostic procedures
One fuse #15 50 amp. No relay , controlled by the TIPM ,computer controlled .

No , no fuse ,get power from TIPM - totally integrated power module . http://www.bbbind.com/free_tsb.html free diagrams . Enter vehicle info year , make , model an engine size . under system click Body & Accessories , under subsystem click on power windows . Click on the search button then click the blue link . Check out the wiring diagram an you will top left the TIPM . Google chrysler ,dodge , jeep TIPM . Have problems with it .
None of your windows work ? Check for broken wires inside the rubber boot from the body to the door , do you know what I'am talking about ? Open the door ?

There isn't a flasher . Controlled by computer , TIPM - totally integrated power module . It's part of the under hood fuse box . Google chrysler TIPM , they have had problems . Check out a wiring diagram at http://www.bbbind.com/free_tsb.html Chrysler Pacifica TIPM Electrical Problems Your best bet , take it to a qualified chrysler dealer .

There isn't a fuel pump relay , it is controlled by the totally integrated power module !

MODULE-TOTALLY INTEGRATED POWER

DESCRIPTION

The Totally Integrated Power Module (2)(TIPM) is a

combination unit that performs the functions of the

Power Distribution Center (PDC) and the Front Control

Module. The TIPM is a printed circuit board based

module that contains fuses, internal relays and a

microprocessor that performs the functions previously

executed by the FCM. The TIPM (2) is located in the

engine compartment, next to the battery (1) and connects

directly to the B+ cable (5) via a stud located on

top of the unit. The ground connection is via electrical

connectors. The TIPM provides the primary means of

voltage distribution and protection for the entire vehicle.

The molded plastic TIPM housing includes a base and

cover. The TIPM cover is easily opened or removed

for service and has a fuse and relay layout map integral

to the inside surface of the cover. The TIPM housing

base and cover are secured in place via mounting

tabs. The mounting tabs secure the TIPM (2) to the

battery tray mounting bracket (3).

OPERATION

All of the current from the battery and the generator output enters the Totally Integrated Power Module (TIPM) via

a stud on the top of the module. The TIPM cover is removed to access the fuses or relays. Internal connections of

all of the power distribution center circuits is accomplished by a combination of bus bars and a printed circuit board.

For complete circuit diagrams, refer to the appropriate wiring information. The wiring information includes wiring

diagrams, proper wire and connector repair procedures, details of wire harness routing and retention, connector
pin-out information and location views for the various wire harness connectors, splices and grounds.

You have no clue of the complexity of these systems , controlled by the TIPM - totally integrated power module . Your best bet would be to take it to the dealer . Recall on TIPM . You do not have the knowlede to fix this .

looking for a fuse diagram for a 2006 buick lacrosse

use test light see if fuse box grounded.hook 12 volt test light to good ground with ignition switch on probe top of all fuses see if test light turn on if yes fuse box getting good ground when you take 12 volt test light touch both sides top of ignition ecm 15 amp fuse and ecm battery 20 amp fuse should light up on both sides if one side left top side fuse light up with test light fuse is blowed.if fuses okay your fuse box has broke wire or inside fuse terminal corroded real bad.
