Codes 1826, 1825 and 1819. Car wont start. Do we need to remove trans to reset? Trans was used.


DTC P1819
Internal Mode Switch-No Start/Wrong Range

DTC P1825
Internal Mode Switch - Invalid Range

DTC P1826
Internal Mode Switch C Circuit High Voltage

The transmission internal mode switch (IMS) is a sliding contact switch attached to the selector detent inside the transmission side cover. The four inputs to the PCM indicate the position of the transmission range selector. The input voltage level at the PCM is high (B+) when the IMS is open and low when the switch is closed to ground. The four input parameters represented are Signals A, B, C and P (Parity). Refer to Transmission Internal Mode Switch Logic

Install a Scan Tool . A professional scan tool !
Turn ON the ignition, with the engine OFF.
Important: Before clearing the DTC, use the Scan Tool in order to record the Freeze Frame and Failure Records. Using the Clear Info function erases the Freeze Frame and Failure Records from the PCM.
Record the DTC Freeze Frame and Failure Records.
Clear the DTC.
Select IMS on the Scan Tool .
Place the gear select lever in PARK range, then move to NEUTRAL range.
Does each range selected match the Scan Tool IMS display?
.Replace the lever assembly-manual shaft detent with internal mode switch.
Refer to Transmission Overhaul in the 4T65-E Section of the Transmission Unit Repair Manual.

It showing code 41. Generator field not switching properley.


This trouble code sets when the Powertrain Control Module (PCM) tries to regulate the generator field with no result during monitoring.
The PCM tries to maintain a system voltage between 12.9 volts and 15.0 volts. The voltage determined by the PCM as the final goal for the charging system is called "control" voltage. This control voltage is determined from the battery temperature sensor for ambient sensor and the sensed voltage system voltage at PCM pin #11.
The control voltage is compared to the sensed voltage continuously during running. If the sensed voltage is less than the control voltage, the PCM will supply more ground to the field circuit. If the sensed voltage is more than the control voltage, the PCM will supply less ground to the field circuit.
There are three possible causes for this, the field driver circuit open or shorted, there is an alternator internal open or short os a PCM failure

Getting p0601 code


Hi I'm Peter, P0601 OBD-II Trouble Code Technical Description

Internal Control Module Memory Check Sum Error
What does that mean? Basically that means that there is an interal fault in the Powertrain Control Module (PCM). There have been many reported PCM failures on Chrysler/Dodge products although it is possible for this to happen on any vehicle.
In Dodge/Chrysler products, a P0601 trouble code means that a serial communication failed inside the computer at least 6 times. Symptoms Likely, no symptoms will be discernible to the driver, other than the illuminated Check Engine Light. Typically the engine runs fine, gauges work, etc.
Causes A code P0601 in most cases means the PCM has gone bad. This is possibly due to a short-circuit inside the PCM. Or, if you disconnect the wires/connector from the PCM while the battery is still connected, that may also cause this code.
Possible Solutions With a P0601 OBD-II trouble code, the most common fix is to replace and reprogram the PCM. In a few cases the dealer may be able to reflash the PCM and get it working. But more than likely the PCM will need to be replaced and reprogrammed (we recommend you take it to a dealership for this). The good news is it *may* be covered under your emmissions warranty. So even if you're out of bumper-to-bumper warranty or powertrain warranty, check your warranty guide or dealer to see if this is covered.
Other people have reported that they cleared the code only for it to return again and again. Keep in mind that most shops can replace the PCM but not all can program it. Hope this is what you needed. Let me know how you make out.

93 grand cherokee runs poorly, check flickers on and off , computer code 53


Code 53 is an internal PCM (engine computer) failure and will require the PCM to be replaced. A rare problem to have, unfortunately.

I HAVE A 2004 HONDA ODYSSEY THE CHECK ENGINE LIGHT CAME ON, THE CODE THAT CAME UP IS P1607 PCM INTERNAL CIRCUIT FAILURE COULD ANYONE PLEASE TELL ME WHAT THAT CODE IS?


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.

Code p1635


The P01535 refers to the 5 volt reference circuit generated by the PCM. The reference voltage is being pulled low for some reason.
If there are no other codes present, the code is indicating the PCM 5 volt output is too low caused by an internal PCM failure.
If you have a volt meter, check the voltage at the TPS ( gray wire and key in run position ) and see what the actual voltage is.
Let me know and we can go from there.
