INSPECT SHIFT SOLENOID VALVE SL4

DTC P2810 Pressure Control Solenoid "G" Electrical (Shift Solenoid Valve SL4)


DESCRIPTION

Shifting gears from 1st through 5th is performed in combination with "ON" and "OFF" operation of the shift solenoid valves SL1, SL2, SL3 and SL4 which are controlled by the TCM. If an open or short circuit occurs in either of the shift solenoid valves, the TCM controls the remaining normal shift solenoid valves to allow the vehicle to be operated smoothly (Fail safe function).

DTC No.
DTC Detecting Condition
Trouble Area
P2810
  1. The TCM checks for an open or short in the shift solenoid valve SL4 circuit while driving and shifting gears.
    (1-trip detection logic)
    1. Output signal duty equals 100%.
      (NOTE: SL4 output signal duty is less than 100% under normal condition.)
  1. Open or short in shift solenoid valve SL4 circuit
  2. Shift solenoid valve SL4
  3. TCM

MONITOR DESCRIPTION

The TCM commands gear shifts by turning the shift solenoid valves on or off. When there is an open or short circuit in any shift solenoid valve circuit, the TCM detects the problem and illuminates the MIL and stores the DTC. And the TCM performs the fail-safe function and turns the other normal shift solenoid valves on or off. (In case of an open or short circuit, the TCM stops sending current to the circuit.)

INSPECTION PROCEDURE

1.INSPECT TRANSMISSION WIRE (SL4 CIRCUIT)


    Camry. Acv40 Gsv40.U660E Automatic Transaxle.Automatic Transaxle System. Dtc P2810 Pressure Control Solenoid G Electrical (Shift Solenoid Valve Sl4)

  1. Remove the TCM from the transaxle.

  1. Measure the resistance according to the value(s) in the table below.

    Standard resistance:
    Tester Connection
    		Specified Condition
    20°C (68°F)
    22 (SL4+) - 21 (SL4-)
    		5.0 to 5.6 Ω

  1. Measure the resistance according to the value(s) in the table below.

    Standard resistance:
    Check for short:
    Tester Connection
    		Specified Condition
    22 (SL4+) - Body ground
    		10 kΩ or higher
    21 (SL4-) - Body ground
    		10 kΩ or higher


OK
REPLACE TCM

2.INSPECT SHIFT SOLENOID VALVE SL4


    Camry. Acv40 Gsv40.U660E Automatic Transaxle.Automatic Transaxle System. Dtc P2810 Pressure Control Solenoid G Electrical (Shift Solenoid Valve Sl4)

  1. Remove the shift solenoid valve SL4.

  1. Measure the resistance according to the value(s) in the table below.

    Standard resistance:
    Tester Connection
    		Specified Condition
    20°C (68°F)
    1 - 2
    		5.0 to 5.6 Ω

  1. Connect a positive (+) lead through a 21 W bulb to terminal 2 and a negative (-) lead to terminal 1 of the solenoid valve connector, then check the movement of the valve.

    OK:
    The solenoid makes an operating noise.
