Pressure Control Solenoid "G" Electrical (Shift Solenoid Valve SL4) (P2810)
DESCRIPTION
Changing from 1st to 6th is performed by the TCM turning shift solenoid valves
SL1, SL2, SL3, SL4 and SL on and off. If an open or short circuit occurs in any
of the shift solenoid valves, the TCM controls the remaining normal shift solenoid
...
Torque Sensor Zero Point Adjustment Incomplete (C1516,C1526)
DESCRIPTION
These DTCs do not indicate a malfunction. The power steering ECU stores these
DTCs when it determines that the rotation angle sensor value initialization and
torque sensor zero point calibration are incomplete.
DTC No.

PROCEDURE
1. RECOVER REFRIGERANT FROM REFRIGERATION SYSTEM
2. DISCONNECT CABLE FROM NEGATIVE BATTERY TERMINAL
NOTICE:
When disconnecting the cable, some systems need to be initialized after the cable
is reconnected (See page ).
