Circuit Description
The TCM uses transaxle input speed information and out-
put speed sensor to control line pressure, TCC apply and
release and transaxle shift patterns. This information is
also uses to calculate the appropriate operating gear ra-
tios and TCC slippage. Conditions for Setting the DTC.
Conditions for Setting The DTC
S Time since TCM reset is greater than 500 msec.
S Time since shift end is greater than 500 msec.S Transmission oil temperature is greater than –10°C
(14°F).
S System voltage is greater than 9 volts.
S No input speed error DTCs P0715, P0716 or
P0717.

DIAGNOSTIC TROUBLE CODE(DTC) P0781
1–2 SHIFT MALFUNCTION
Circuit Description
The special feature of 4HP 16 Auto Transaxle is that it op-
erates without freewheels. Shifting between individual
gears takes place by means of overlapping clutch engage-
ment and release.
The advantage of overlap shifting are as follows:
–The transaxle can be of more compact design and
is lighter on account of the absence of freewheels
and the lower number of shift elements.–Lower drag losses, i.e. higher efficiency.
–Lower peak torque acting on the components and
driveline.
However, overlap shifting necessitates high–performance
hardware and software, and precision engine signals.
Conditions for Setting The DTC
S Transmission oil temperature is greater than –10°C
(14°F).
S Selector lever is not N(Neutral), P(Park) position.
S System voltage is greater than 9 volts.

S No input speed error DTCs P0715, P0716, and
P0717.
S Output speed is greater than 256 rpm.
S Input speed is greater than 400 rpm.
S 1–2 gear shift is active.
S Immediately after the above condition occurs.
Action Taken When The DTC Sets
S The Malfunction Indicator Lamp(MIL) will illuminate.
S The TCM will record operating conditions at the
time the diagnostic fails. This information will be
stored in the Failure Records buffer.
S Adopt Emergency/ Substitute mode and constant
1st gear.S Open lock up clutch.
Conditions for Clearing the MIL/DTC
S The MIL will turn OFF when the malfunction has
not occurred after three–ignition cycle.
S A history DTC will clear after 40 consecutive warm
up cycles without a fault.
S Using a scan tool can clear history DTCs.
Diagnostic Aids
S When DTC P0781 sets, the possible cause of fault
could be TCM.
