DAEWOO V–121 BL4
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.
S No lockup control

Conditions for Clearing the DTC
S The TCM turns off the MIL when no further failures
detected for three consecutive ignition cycles.

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.
