1. CHECK FOR INTERMITTENT PROBLEMS
HINT:
A momentary interruption (open circuit) in the connectors and/or wire harnesses
between the sensors and ECUs can be detected using the ECU Data List function of
the Techstream.
(a) Turn the ignition switch off.
(b) Con ...
Pressure Control Solenoid "A" Circuit Open (P074513)
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 ...
Vehicle Speed Signal Circuit between Stereo Component Amplifier and Combination
Meter
DESCRIPTION
The stereo component amplifier assembly receives a vehicle speed signal from
the combination meter assembly to control the ASL function.
HINT:
A voltage of 12 V or 5 V is output from each ECU and then input to the
combination meter assembly. The signal is changed to a pu ...
