Electrical Ground Repair Overview



Proper electrical system function relies on secure, stable and corrosion-free electrical ground connections. Loose, stripped, or corroded connections



increase the possibility of improper system function and loss of module communication. These conditions may also lead to unnecessary repairs and



component replacement.



In general, electrical ground connections are accomplished using one, or a combination of the following attachment methods:



- Welded M6 stud and nut



- Welded M6 nut and bolt



- Welded M8 nut and bolt



Determine which attachment method is used and perform the appropriate or alternative repair as described in this bulletin.

- Generator L-Terminal Circuit High Voltage



Diagnostic Fault Information



Circuit/System Description



The engine control module (ECM) uses the generator turn on control circuit, or L-terminal circuit, to control the load of the generator on the engine.



A high side driver in the ECM applies a voltage to the voltage regulator. This controls the voltage regulator to turn the field circuit ON and OFF.



The ECM monitors the state of the generator turn ON control circuit. The ECM should detect low voltage on generator turn on control circuit when



the ignition is ON and the engine is OFF, or when the charging system malfunctions. With the engine running, the ECM should detect high voltage



on the generator turn on control circuit. The ECM performs tests to determine the status of the generator turn on control circuit.

Diagnostic Fault Information



Circuit/System Description



The control module enables the appropriate fuel injector on the intake stroke for each cylinder. Ignition voltage is supplied directly to the fuel



injectors. The control module controls each fuel injector by grounding the control circuit with a solid state device called a driver. The control



module monitors the status of each driver. Each driver has a feedback voltage circuit which the Engine Control Module (ECM) monitors. The



injector control circuits are pulled-up to voltage within the ECM. The ECM can determine if a control circuit is open, shorted to ground, or shorted

* The engine speed is 400 RPM or greater for 5 seconds.



* The engine speed is 550 RPM or greater.



* Ignition voltage is 8.6 volts or greater.



* The transmission fluid temperature (TFT) is 0-120掳C (32-248掳F).



Conditions for Setting the DTC



P0877



The TCM detects that the TFP switch 4 signal voltage remains LOW after the 1-2-3-4 clutch transitions from a HIGH pressure state to a LOW



pressure state. The TCM counts each incident. The DTC sets when 5 counts are accumulated.



P0878



The TCM detects that the TFP switch 4 signal voltage remains HIGH after the 1-2-3-4 clutch transitions from a LOW pressure state to a HIGH



pressure state. The TCM counts each incident. The DTC sets when 8 counts are accumulated.



Action Taken When the DTC Sets



* DTCs P0877 and P0878 are Type C DTCs.



* The TCM freezes transmission adaptive functions for the 1-2-3-4 clutch.



Conditions for Clearing the DTC



DTCs P0877 and P0878 are Type C DTCs.



Diagnostic Aids



A TFP switch may malfunction due to normal debris in the transmission fluid causing a TFP Switch DTC to intermittently set. This type of failure



should not be immediately noticeable to a customer, as the switch outputs are used for shift adaptives and do not cause transmission symptoms



unless the switch malfunctions continuously for an extended period of time.
