5A-120 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 P1737 sets when the solenoid 5 (S5) circuit
is open or the switched leg of the solenoid 5 is shorted
to battery positive. The solenoid 5's driver Integrated
Chip (IC) status indicates a fauty circuit.
Conditions for Setting the DTC
•
DTCs P1717 and P1718 are not set.
•
The solenoid 5's driver Integrated Chip (IC) status
indicates a faulty circuit. This condition must be
continuously present for 60 milliseconds.
•
The measured S5 current is greater than 100 mA
below its expected lower limit.
Action Taken When the DTC Sets
•
Solenoid 5 is disabled (always OFF).
•
The shift quality is degraded.
DIAGNOSTIC TROUBLE CODE (DTC) P1737
SOLENOID 5 CIRCUIT OPEN
Conditions for Clearing the DTC
•
The DTC will clear when the malfunction has not
occurred after ignition cycle.
•
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 an open circuit or short
circuit to power 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 damaged 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 in-side the insulation.
