5A-124 AUTOMATIC TRANSMISSION
Circuit Description
The solenoid 6 is a normally open ON/OFF type sole-
noid that is used to set the high/ low level of line pres-
sure.
The Solenoid 6 (S6) OFF gives high pressure and the
S6 is attached to the valve body within the
transmission. Voltage is supplied directly to the
solenoid through the Transmission Control Module
(TCM).
The DTC P1738 sets when the solenoid 6 circuit is
open or the switched leg of the solenoid 6 is shorted
to battery positive. The solenoid 6's driver Integrated
Chip (IC) sta-tus indicates a faulty circuit.
Conditions for Setting the DTC
•
DTCs P1717 and P1718 are not set.
•
S6 is OFF.
•
S4 is OFF.
•
The solenoid 6'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
•
The solenoid 6 is disabled (OFF) resulting in high
line pressure being applied continuously.
DIAGNOSTIC TROUBLE CODE (DTC) P1738
SOLENOID 6 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
•
During the TCM's testing, solenoid 6 is turned OFF/
ON by a very small (4 millisecond) pulses. This
pulse is too short for the solenoid to react so the
transmission operation is not affected.
•
The solenoid feedback voltage is measured before
the (4 millisecond) pulse and again during the pulse.
If the difference is outside the acceptable limits
the relevant fault is recorded.
•
Typical causes would be an open circuit in the wiring
to or within the solenoid, or a short circuit to power
in the wiring to or within the solenoid.
•
If several faults of solenoids are present, check the
wiring or connectors that are common to the selected
solenoids, especially the earth connections.
