Diagnostic Trouble Code(DTC) P1839

EDS 3 Output Shorted to Ground

Circuit Description

The pressure control valves (EDS valves 3,4,5 and 6) are precision electronic pressure regulators that control the operation of the clutches, brakes and lock-up clutch.
The valve reduces the system pressure with which the downstream solenoid valves and electrical pressure regulating valves are supplied. It is possible to use smaller solenoid valves as a result. The EDS require a constant input pressure.

Diagnostic Trouble Code(DTC) P1850

Solenoid 1 Output Shorted To Ground

Circuit Description

The shift solenoids are two identical, normally open electronic exhaust valves that control upshifts and downshifts in all forward gear ranges. These shift solenoids work together in a combination of ON and OFF sequences to control the line pressure and shift mechanisms(clutches, brakes).
Solenoid 1 controls the high or low of the line pressure (flow to each clutch valve) by the operation type (ON/OFF), i.e. solenoid 1 is ON, line pressure will be low (87~116psi (6~8bar)), solenoid 1 is OFF, line pressure will be high (232~261psi (16~18bar)). Solenoid 2 controls the oil flow to clutch valve E or lock-up clutch valve by the ON/OFF signal.
The TCM monitors numerous inputs to determine the appropriate solenoid state combination and transaxle gear tor the vehicle operating conditions.

Diagnostic Trouble Code(DTC) P1854

Solenoid 2 Output Shorted To Power

Circuit Description

The shift solenoids are two identical, normally open electronic exhaust valves that control upshifts and downshifts in all forward gear ranges. These shift solenoids work together in a combination of ON and OFF sequences to control the line pressure and shift mechanisms(clutches, brakes).
Solenoid 2 controls the high or low of the line pressure (flow to each clutch valve) by the operation type (ON/OFF), i.e. solenoid 2 is ON, line pressure will be low (87~116psi (6~8bar)), solenoid 1 is OFF, line pressure will be high (232~261psi (16~18bar)). Solenoid 2 controls the oil flow to clutch valve E or lock-up clutch valve by the ON/OFF signal.
The TCM monitors numerous inputs to determine the appropriate solenoid state combination and transaxle gear tor the vehicle operating conditions.
