5A-148 AUTOMATIC TRANSMISSION
Circuit Description
The solenoid 5 is a variable force solenoid that ramps
the pressure during the gear changes and solenoid
switching, to enhance the transmission shift quality.
This solenoid provides the signal pressure to the clutch
and band regulator, thereby controlling the shift
pressure.
The solenoid 5 is attached to the valve body within
the transmission. Voltage is supplied directly to the
solenoid through the Transmission Control Module
(TCM).
The DTC P1745 sets when the Solenoid 5 (S5) circuit
is shorted to ground. The solenoid 5's driver
Integrated Chip (IC) status indicates a faulty circuit.
Conditions for Setting the DTC
•
DTCs P1717 and P1718 are not set.
•
S5 is ON.
•
The solenoid 5's driver Integrated Chip (IC) status
indicates a faulty circuit. This condition must be
continuously present for 60 milliseconds.
Action Taken When the DTC Sets
•
Solenoid 5 is disabled (always OFF)
•
The shift quality is degraded.
Conditions for Clearing the DTC
•
The DTC will clear when the malfunction has not
occurred after ignition cycle.
DIAGNOSTIC TROUBLE CODE (DTC) P1745
SOLENOID 5 CIRCUIT SHORT
•
A history DTC will clear after 40 TCM power-up
cycles with a warm transmission (>50 ° C) and
without a fault.
•
History DTCs can be cleared by using a scan tool.
Diagnostic Aids
•
The current to solenoid 5 was outside acceptable
limits.
•
This fault results from a mismatch between the cur-
rent set point for solenoid 5 and the current
measured by the feedback within the TCM.
•
Typical causes would be a short circuit to ground
in the wiring to, from or within the solenoid.
•
It is also possible that there has been a fault in the
solenoid output circuit. But if this is the cause, the
fault should be continually present.
•
Inspect the wiring for poor electrical connections
at the TCM and at the 10-way transmission
connector. Look for possible bent, backed out,
deformed or dam-aged terminals. Check for weak
terminal tension as well. Also check for chafed wires
that could short to bare metal or other wiring.
Inspect for broken wire inside the insulation.
•
If diagnosing for a possible intermittent short or
open condition, move or massage the wiring
harness while observing test equipment for a
change.
