Code u0121 please how do i fix it

year 2000? not really huh?
seems the year is wrong,
so if that is true ,is car wrong too, JEEP and grand cherroke wrong too?
for example the 2011 Compass / Patroit
2011 (tsb to replace Pcm) ( have TSB, google finds it easy)

1: get it serviced yet?
2: read the FSM WJ book yet, do all tests it tells you to do ?
there are only 2 paths.
they do it , you do it.?
which one?

WJ 00 (dead end, no code there, OP posted wrong year,. )

U codes are specific to specific jeeps. and years.
posting wrong car....
makes answers impossible. did you scan it yet?

but one thing, we do , is check fuses first.
if the ABS module does not talk, if in fact it is ABS code.
and scan it, first. too.
fuses then scan.
or fail.

these are factory codes, not usa federal codes like P-0300
so post full car spec, and engine, type for best answers.
lets say car is a 2005 GC.
and U0121
see chapter 8E-72 in fsm tells you what to do,
if car is 3rd gen jeep GC, then it has this buss.
the below is the buss, the can c bus
the code means PCM cant talk to the ABS box.
id be all over fuses. and resetting them all.

P1607 code

you have an ECM malfunction
P1607 is an internal failure of the PCM. Before replacing I would check the connectors and reseat them . Check battery voltage also.

After seeing another post check for rodent damage to the wires...

I have trouble starting my van and later on the check light came on (P1607). The car can no longer start but sometimes when I fiddle with the battery it would start up again and when it does it runs fine....

P1607 means "powertrain control module (PCM) internal circuit malfunction". According to the factory service manual, a low battery condition can cause this. This code can also pop up after the battery has been jump started.

You need to reset the PCM. To do this, turn the ignition switch off. Remove the No. 13 fuse (7.5Amp) from the passenger's under dash fuse/relay box for at least 10 seconds. Put the fuse back in. That should complete the reset.

Now to check again for the code: turn the ignition switch to on (not start.) Wait 30 seconds. If the check engine light stays OFF, turn the ignition switch off and wait 10 seconds. Turn the ignition switch back to on (not start). Wait 10 seconds. If the check engine light stays OFF, you had an intermittent fault and it has now been reset--everything is fine. If the check engine light comes back on during these checks, have the code that set read out. If the code is P1607 again, then you may have to have the PCM tested at the dealership for an internal fault.

I have a Honda Oddysey 1998, and in the scanner show the code P1607

P1607 Engine Control Module (ECM)/Powertrain Control Module (PCM) Internal Circuit Malfunction.

aquire the appropriate pinout diagram for your ecu's plugs. then proceed to verify each of the ecu's power wires have the correct voltage. then proceed to perform a continuity test on all ecu grounds. this means checking voltage from the ecu plug to the ground location that the wire goes to. you should find your problem somewhere within there if you have already swapped out with a KNOWN GOOD ecu.

this code can sometimes set due to low battery voltage. find the cause of the low battery voltage(this code usually pops up after a car is jump started or the battery is replaced or gone bad). clear the code. if it returns, then yes, the pcm will need replaced.
