P0700-INTERNAL TRANS CONTROLLER When Monitored: Continuously with key on. Set Condition: Watchdog test not in progress. The code sets if the delay/monitor line is low too long and/or the switched battery is low for more than .5 secs. A Dealership should diagnose this condition to determine the Good trip counter. If the number is greater than 3, then further diagnosis by a qualified technician may be necessary. POSSIBLE CAUSES CHECKING SYMPTOMS AND POSSIBLE CAUSES: LOW BATTERY VOLTAGE CAUSING SYMPTOM, INTERMITTENT CODE P0700. GLOBAL GOOD TRIP COUNTER LESS THAN 3 Starts. SETTING DIAGNOSTIC TROUBLE CODE 0700. With the DRBIII or Scan tool, read DTC’s. If the Starts Since Set Counter 3 or less. Replace TCM. 2 Record all DTC’s and one trip failures. With the DRBIII or Scan tool, erase DTC’s. Turn the Ignition From Off to On. If no Limp-in occurs, start the Engine. Did the erased DTC come back ? Replace TCM. This code normally points to a faulty transmission control module, but this is an expensive part and you should have an experienced Dodge technician diagnose the problem first.

had a code of P0700 replaced battery seems to run fine but battery light is on never has been before. Is there something I need to reset so that battery light goes out . Meter reads no codes found since replacing battery but the battery light worries me.
