Tips

 

There are a lot of fault codes that indicate to Jeep Grand Cherokee WJ transmission malfunctions and limp mode. You can study the list provided below. Addition to those mentioned, also P1242, P2210 and P2212 may occur due to data communication errors which result from broken Jeep gear shifter (mostly), Transmission Control Module (TCM) or wiring between Engine Control Unit (ECU) and TCM.

It is possible to fix the gear shifter, but you would need hard-to-get microchips and it can break again soon due to oxidation.

Below you can find some most common faults that may be related to fault code P0702.

1. P2602 Solenoid Valve: power supply Value/signal outside range.

This fault is very common, it means that transmission solenoids are not getting enough power. With this code there can be 2 reasons – gearbox plug adapter or weak battery. About gearbox plug adapter you can look at tip 4.  If adapter is fine, then your car has a weak battery and you need to change it. You can also avoid battery fault by asking Jeep dealer to upgrade TCM software. Upgrading software does not make your battery new, it just does not let your car to go into limp mode for this fault. Until you can’t start your car on a cold winter morning as you battery is still weak…

2. Gear shifter lever, OEM codes 52104468AJ, 52104468AC, 52104468AD, 52104468AE, 52104468AF, 52104468AG, 52104468AH, 52104468AI



These are the most common and expensive faults that can lead to P0702. You have to replace the Gear Shifter Lever PCB Board.

3. Weak battery or bad battery connectors.


Your Jeep Grand Cherokee's transmission can go into limp mode if you are using a weak battery. You should check the battery and cables from both ends, battery and car. If the limp mode is caused by bad battery then you can upgrade the Transmission Control Module software at your dealer. This upgrade won't make your battery better, but does not allow TCM to go into limp mode cause of undervoltage. To avoid starting problems in future, you should still change the battery soon.

4. Gearbox plug adapter, OEM 68021352AA


Transmission plug adapter is located under the car and often starts leaking oil. Once oily, the plugs have bad electrical connection and transmission goes into limp mode and starts showing fault codes. It is easy to check the plug - look under the car and check if the plug is oily. If it's oily - get it replaced. Also check if the cables are fine - with time the isolation can crack and cables can go to short circuit. Then the outcome is again P0702 and limp mode. You can easily fix it with some tape.

5. Bad solderings in TCM.


The solderings of the plugs of Transmission Control Module can crack with time. Disassemble the TCM and use magnifier to check the solderings of both plugs. If you can see any circles on the solderings then resolder them. You can resolder them for "just in case" as well. TCM is located on the right side of shifter assembly, near the passenger legs.

6. Transmission Valve Body Electrical Plate, OEM codes: 1402700161, 1402700361, 1402700561, 1402700761, 1402700861, 1402701161


There are some sensors in this plate and if your vehicle is showing the codes P0715 and P0720, this is most likely your problem. This plate is located inside the gearbox, but replacing it is not difficult.

7. Different fault codes when ECU cables has broken by steering shaft


One reason can be broken cable fastening - the cable has moved from its correct position and rubs against other parts. Check in engine bay under the battery if the steering shaft frictions the cables coming from Engine Control Module. You can check it with a mirror that is attached to a long rod. You need to check if the fastening of the bundle of cables is intact and that they have not been rubbing against the steering shaft. As there is lot of cables in this place, then can be different fault codes - data bus, sensors, power etc.
If you can check your engine fault codes then you can do this - delete all faults from engine, then start your car and turn steering wheel to left and right. If this makes the code to return, then it is your wiring that is broken.
To fix this you'll need to take off the battery, the plate under the battery and isolate/fix the broken wiring.
You should also look at this place when you have some other incomprehensible electrical issue and you can not find reason for it.

8. Fault code P0836 caused by Transfer case position sensor, OEM 5083138AA


P0836 is also very common transmission fault. It makes MIL light on and car will be in limp mode.
Problem is Transfer case position sensor or it’s wiring. You can check sensor, oxidation of ECU (in engine bay on driver side) pin no. 29 and wire between ECU and sensor.

9. Fault code P0700 is caused by solenoids


P0700 is also transmission electrical fault, but it is related with transmission solenoids and if you have this code instead of P0702, then you should look at solenoids, TCM or wiring between them.

10. No gear position lights on shifter and no fault codes.


If there is no yellow position lights on shifter, then in most cases shifter board is broken. Just in case you can check at shifter board input voltage. Measure voltage on shifter board main socket plug, pin 1 is +12V and pin 11 is ground. If you get +12V from those plug pins with ignition on, then fuses and wiring are fine and shifter board is broken. If there is not +12V, then you should look at fuse F12 on top of driver legs and wiring between fuse box and shifter board.
Electricity coming from battery>fuse block>shifter board>TCM. If power is cut somewhere, then TCM may not have fault codes since TCM does not get +12V and is switched off.

 

Your Jeep Grand Cherokee can also go to the limp mode due to ABS control unit located in engine bay. You can check this with proper diagnostics device.

We will be happy to help you in identifying the errors, however, for this we need to know all the engine and TCM fault codes readed by proper diagnostics device. Ignition ON/OFF method shows only engine fault codes and we can not provide an adequate answer without TCM fault codes.

Retrieving ECU fault codes:
Turn the ignition key until the digital odometer displays, repeat three times in succession and then back to “On” (On/Off, On/Off, On/Off, On). At the fourth “On” the odometer will be replaced with codes.
With key on-off method you can only see engine ECU faults. For TCM faults you’ll need a proper diagnostics device as DRB III or Bosch KTS. Those devices are very expensive and we made a free program for reading/clearing engine and transmission faults for 2.7 Jeep Grand Cherokee. It works with ELM327 based diagnostic device, you can get it from ebay for 5 EUR. Check at our software page.

Jeep Grand Cherokee WJ 2.7 CRD limp modes and MIL illumination.

Permanent limp-in mode.

When the TCM determines there is a non-recoverable condition present that will not allow proper transmission operation, it will place the transmission in permanent limp-in mode. When the condition occurs the TCM will turn off all solenoids as well as the solenoid supply output circuit. If this occurs while the vehicle is moving, the transmission will remain in the current gear until the ignition is turned off or shifter is placed in the P position. Once the shifter has been placed in P the Transmission will only allow 2nd gear operation. . If the problem occurs while the vehicle is not moving the transmission will only allow 2nd gear operation.

Temporary limp-in mode.

This mode is the same as the permanent limp-in mode except if the condition is no longer present the system will resume normal operation. (Recoverable DTC)

Undervoltage limp-in mode.

When the TCM detects that system voltage has dropped below 8.5 volts it will disable voltage dependant diagnostics and place the transmission in the temporary limp-in mode. When the TCM senses that the voltage has risen above 9.0 volts, normal transmission operation will be resumed.

Hardware Error Mode.

When the TCM detects a major internal error the transmission will be placed in the permanent limp-in mode and cease all communication over the CAN bus. Once the TCM has entered this mode normal transmission operation will not resume until all DTC’s are cleared from the TCM.

Loss of Drive.

If the TCM detects a situation that has resulted or may result in a catastrophic engine or transmission failure, the transmission will be placed in the neutral position. Improper Ratio, Input Sensor Overspeed, or Engine Overspeed DTC’s will cause the loss of drive.

Controlled Limp-in Mode.

When a failure condition does not require the TCM to shut down the solenoid supply, but the failure is of a degree where the TCM will place the transmission into a predefined gear, there will be several shift performance issues. Examples of this are, with the transmission slipping the controller will attempt to place the transmission into third gear and maintain third gear for all forward drive conditions. Another example is some of the CAN bus message issues if the TCM does not receive required information from the Engine Controller, then default values are used which may result in poor transmission shift performance.

MIL ILLUMINATION.

For failures detected by the Transmission Controller that result in the controller placing the transmission into a limp-in mode, except for System Overvoltage and System Undervoltage DTCs, the MIL will be illuminated. The Transmission Controller will inform the PCM/ECM over the CAN bus that a failure has occurred. The PCM/ECM will store one of two DTC’s P0700 or P0702 depending on which transmission DTC is present and will illuminate the MIL. If the condition is removed and the failure becomes Stored (Intermittent), the Transmission controller will stop reporting that the DTC is active and the PCM/ECM will extinguish the MIL.
Note: The MIL will light when the problem is first detected and it will not go off until the next ignition cycle, after all problem conditions have been checked for their presence. This normally takes several minutes of driving.
