DIAGNOSTIC TROUBLE CODE (DTC) P0753
SHIFT SOLENOID 1 (SS1) ELECTRICAL
Conditions for Setting the DTC
S TCM detects that the ON signal of the Shift Sole-
noid 1 (SS1) monitor during 0.5 seconds when SS1
driver outputs the OFF signal.(When the SS1 circuit
is open or short to battery).
S TCM detects that the OFF signal of the Shift Sole-
noid 1 (SS1) monitor during 0.3 seconds when SS1
driver outputs the ON signal.(When the SS1 circuit
is short to ground).
S The above detection 2 times at shifting continuous-
ly.
Action Taken When the DTC Sets
S TCM will request the illumination of MIL and store
DTC when TCM detects a failure on the first ignition
cycle.

Conditions for Clearing the DTC
S The TCM turns off the MIL when no further failures
detected for three consecutive ignition cycles.
S The scan tool can clear the DTC from the TCM his-
tory.
S The TCM clears the DTC from the TCM history
memory after forty consecutive warm up cycles
without fault.
S TCM detects the ON signal of the SS1 monitor dur-
ing 160 ms when SS1 driver outputs the ON signal
and TCM detects the OFF signal of the SS1 moni-
tor during 160 ms when SS1 driver outputs the
OFF signal.

noid (ST) monitor during 0.5 seconds when ST driv-
er outputs the OFF signal.(When the ST circuit is

FLUID COOLER FLUSHING
Flushing Procedure
1. Drain the fluid from the transaxle and refill the
transaxle with new transaxle fluid. Refer to ”Fluid
Drain Procedure” in this section.
2. Let the engine idle for 5 minutes.
3. Drain the fluid from the transaxle and refill the
transaxle with new transaxle fluid. Refer to ”Fluid
Drain Procedure” in this section.
CONTROL CABLE ADJUSTMENT
Adjustment Procedure
The various shift control cable positions must match at the
shift control lever in the vehicle and at the selector lever
on the transaxle to provide proper transaxle shifting.
Place the shift control lever in the PARK position and
check the selector lever connection to verify that it is in the
forward most position. If it is not, the following adjustment
must be performed:
1. Disconnect the negative battery cable.
2. Remove the floor console. Refer to Section 9G,
Interior Trim.
3. Place the shift control lever in the PARK position.
4. Loosen the control cable adjusting nut.
5. Move the Transmission Range (TR) switch lever
counterclockwise until stopping the lever.
