1. DATA LIST
HINT:
Using the Techstream to read the Data List allows the values or states of switches,
sensors, actuators and other items to be read without removing any p ...
Other materials:
Pressure Control Solenoid "C" Electrical (Shift Solenoid Valve SL3) (P0798)
DESCRIPTION
Changing from 1st to 6th is performed by the ECM turning shift solenoid valves
SL1, SL2, SL3 and SL4 on and off. If an open or short circuit occurs in any of the
shift solenoid valves, the ECM controls the remaining normal shift solenoid valves
to allow the vehicle to be operated ...
System Voltage Circuit Short to Ground or Open (P056014)
DESCRIPTION
The battery supplies power to the ECM even when the ignition switch is off. This
power allows the ECM to store data such as DTC history, freeze frame data and fuel
trim values. If the battery voltage falls below a minimum level, the ECM data is
cleared and the ECM determines that ...
