Radio Volume and Sound Issues:
The fact that the radio is on but the volume knob doesn't respond and there's no sound from any source suggests a problem with the Digital Signal Processing (DSP) module. This module is responsible for audio processing and distribution.
The C1001:01-68 code points to a fault in the rear camera, while the B1215:00-28 code indicates an issue with the Accessory Protocol Interface Module (APIM).
Since the HVAC and GPS are functioning correctly, it's likely that the APIM itself is not operating as expected.
To address the sound issue, consider replacing the DSP module. Here are the steps:
Remove the subwoofer (it's held in place by three bolts).
Install the new DSP module.
Use FORScan to program the replacement module.
Backup Camera Issue:
The backup camera has also stopped working, displaying a message to contact the dealership.
You might want to try the following common fixes:
Master Reset via Software in SYNC 2: This can sometimes resolve camera issues.
Forced Reset via Disconnecting the Battery: Disconnect the vehicle battery for a few minutes and then reconnect it. This can reset various modules, including the camera.
Replacing the Camera Itself: If the camera remains unresponsive, consider replacing it
rev up.
it needs service.
do a tune up yet,? no country told
all filters? air and fuel replaced is first.
no miles told since last turn up service,
or bad fuel.
and more. lots more, and lots of tests , tools you do not have.
what engine is in the car? size and if Gas or Diesel.
well the service manual covers all that and more.
some cars have no such module at all.
as back in 1996 the trend was to move the TCM into the ECM box
and call it a PCM.
insome cases , like diesel transmission option they had to put in a TCM to make t work
no country told, no VIN TOLD so I can decode the drive line codes.
there is no generic photos of these parts.
each car is made with options, and the parts match that only.
Unique photos yes.
885
A/T Control Relay - Open Or Short To Ground
the glove box users guide under fuse ,should show
A/T control relay location and is fuse #6 near by.
I was right, there is no TCM
the TCM is part of PCM. clearly
the relay is hidden well. inside car, on top of tranny hump
goes to 3rd gear stuck, fail safe it tells in the FSM
my guess no such thing.
post a real problem (evidence and symptoms)
my will guess is the ignition key is dead>>
or alarms go off as you sleep
see how stating a problem puts the helper on track?
most cars the ALARM is part of the BCM body brain
I have no books for Africa only USA and Canada. here.
no country told.
no year car told
no W code told w201 up. by year,
did not scan the OBD2 port yet? see errors>?
made 1993 to now
nobody can guess cars, you just tell firts what it is.
the car needs service, (CEL /SED lamp glows ) means that.
so get it serviced or learn to do that and buy the service manual to learn. tests.
tick over = idling. sure.
my guess it needs fuel and filters. (they are clogged)
2.0L diesel engine it is.
it needs to be scanned for sure.
a very expensive car!, so never serviced it?
4.7L jeep
the p07 code is tranny error.
cutting off all power means , power to rear wheels or DC battery power to some things ,electrical things die?)
on all cars, DC power must be good first or the computers fail or go mad.
P0455 is gas cap loose, ignore it until all else is cured.
unless cap is missing sure.
Shift Solenoid "D" Malfunction. 0755
fix DC power distribution problems first.
bad grounds, bad connectors, alternator weak or dead
fuses blown or loose
loose wire lugs, or connectors.
rusty ground lugs wires.
title ,DIES Driving.
so dies means engine stalls. not tranny slip right.?
if is stalling can you save the stall before it completes the stall
by fast right foot actions
when it stalls tell the helper all other electrical things that die at the event. Radio dead, head lamps and parking lamps dead.
heater or AC cool blower dead?
Seems to me a pure electrical failure so far.
in what country is this truck. 25,950 GVW (sized)
the service manuals are by country, and VIN code
the dealer sells service manuals. buy one.
most trucks and cars, 99%
open the glove box
remove users guide
open index page
see the word FUSE or Relay.
most times the relay is near the fuse. can be.
Did you scan the OBD2 port for errors first. (we do it first)
the check fuses.
then hunt Relays if it has one at all.
if you read the lids it tells the names
in all these places
https://youtu.be/TuovjweoA14
the manual also says some countries, there is no horn at all.
(the manual say where found)
clearly
or it has AIR Horn OPTION, listed in the manual too.
says too, under options steering wheel without horn option.
yeah.
my guess is , the fuse and relay are part of the Horn kits
I see them listed in the parts pages.
best is buy the book, or search for relays all over the truck
as the video shows.
You need to determine where the noise is coming from. Check your power steering fluid and make sure it is full. Remove your serpentine belt and see if the noise goes away, That will let you know if it is coming from the engine or an accessory or pulley bearing. If the noise goes away whith the belt removed, check the alternator bearing and pulley bearings. If the noise is still there whith the belt removed, that means it is either in the engine or transmission.
Some potential solutions:
EGR (Exhaust Gas Recirculation): You mentioned that you cleaned the EGR, but it's still showing as a fault. The EGR system recirculates exhaust gases back into the intake manifold to reduce emissions. If the EGR valve is malfunctioning or clogged, it can affect engine performance.
Here are some steps to consider:
Check for Vacuum Leaks: Inspect the vacuum lines connected to the EGR valve for leaks or cracks. A vacuum leak can disrupt EGR operation.
Test the EGR Valve: Use a vacuum pump to check if the EGR valve opens and closes properly. If it doesn't, consider replacing it.
Clean the Intake Manifold: Sometimes carbon buildup in the intake manifold can affect EGR flow. Clean the intake manifold thoroughly.
Thermostat: You've already replaced the thermostat, which is good. A faulty thermostat can cause overheating or poor engine performance. Make sure the new thermostat is functioning correctly.
System Voltage Low: This could be related to the charging system (alternator, battery, or wiring).
Here are some steps to troubleshoot:
Check Battery Voltage: Measure the battery voltage when the engine is off and when it's running. It should be around 12.6V when off and around 13.8-14.4V when running.
Inspect Alternator: Ensure the alternator is charging properly. If it's not, consider replacing it.
Check Grounds and Wiring: Loose or corroded connections can cause voltage issues. Inspect battery terminals, ground connections, and wiring.
Idle Issues: If the engine won't idle properly, consider the following:
Idle Air Control Valve (IACV): The IACV controls idle speed. Clean or replace it if necessary.
Throttle Body Cleaning: A dirty throttle body can affect idle quality. Clean it using throttle body cleaner.
Vacuum Leaks: Check for vacuum leaks around the intake manifold, hoses, and gaskets.
Timing Chain: The B12D1 engine uses a timing chain. However, if it's stretched or worn, it can cause issues like poor performance or stalling. Consider having the timing chain inspected and replaced if needed.
Remember that diagnosing engine issues can be complex, and it's often best to consult a professional mechanic or use diagnostic tools.
An engine misfire is unlikely to cause that scenario. You need to know what the codes are, but there is more to this. A professional scan tool computer can diagnose the reason. A small hand held scanner is not enough. The pro version can record what happens to make it turn off.

There is an oil seal at this area that delivers the rotational power of the engine to the transmission. There is an additive that you can add to your oil that can help to regenerate the oil seals by softening them up. I am guessing the shady mechanic did this rather than replacing it.
