What happens when the transmission control system malfunctions?
When the TCM detects a malfunction with the control, a signal is send to the Engine Control Module ( ECM) to trigger the Engine Light or Service Engine Soon light. The ECM stores the P0700 code and it means the TCM detected a malfunction with the transmission controls.
How does the Transmission Control Module ( TCM ) work?
The Transmission Control Module (TCM) monitors the malfunction of sensors and actuators relating to transmission control. When the TCM detects a malfunction with the control, a signal is send to the Engine Control Module ( ECM) to trigger the Engine Light or Service Engine Soon light.
What is a p0700 transmission control system malfunction?
P0700 is an informational code only. It doesn’t point to a direct fault in the engine, only a general fault in the transmission. More diagnosis is necessary to identify what the transmission fault is. This requires a scan tool that will communicate with the transmission module.
Why does TCM show an error code of p0700?
Transmission solenoid regulates the flow of fluid in the automatic transmission. So if there will be any problem in it TCM will detect and show the p0700 error code. If the transmission fluid level is low or it has become old then there might be an issue in the transmission leading to the p0700 error code.
When the TCM detects a malfunction with the control, a signal is send to the Engine Control Module ( ECM) to trigger the Engine Light or Service Engine Soon light. The ECM stores the P0700 code and it means the TCM detected a malfunction with the transmission controls.
What is the diagnostic code for transmission control system?
P0700 is a diagnostic trouble code (DTC) for “Transmission Control System Malfunction”.
P0700 is an informational code only. It doesn’t point to a direct fault in the engine, only a general fault in the transmission. More diagnosis is necessary to identify what the transmission fault is. This requires a scan tool that will communicate with the transmission module.
How does the Transmission Control System ( TCS ) work?
The engine control module (ECM) communicates with the TCM to monitor the automatic transmission for faults. If the TCM detects a fault in the automatic transmission and sets a transmission related fault code, the ECM is informed of this also and sets a P0700 in the ECM memory.
