DTC P0758 (European and N. American Emissions)

DTC Descriptor
This diagnostic procedure supports the following DTC:

DTC P0758 2-3 Shift Solenoid (SS) Control Circuit

Conditions for Setting the DTC
^ The transmission control module (TCM) detects that the ON signal of the shift solenoid (SS) 2 monitor during 0.5 second when the SS 2 driver outputs the OFF signal. The SS 2 circuit is open or short to battery.
^ The TCM detects that the OFF signal of the SS 2 monitor during 0.3 second when the SS 2 driver outputs the ON signal. The SS 2 circuit is short to battery.
^ The above detection 8 times at shifting continuously.

Action Taken When the DTC Sets
^ The TCM will request the illumination of the malfunction indicator lamp (MIL) and store the DTC when the TCM detects a failure on the first ignition cycle.
^ No lockup control
^ No engine torque reduction control
^ No engagement pressure control
^ No timing solenoid control for N-D
^ No self-learning control
^ After failure decision: emergency mode





Conditions for Clearing the DTC
^ The TCM turns off the MIL when no further failures are detected on the next ignition cycle.
^ The scan tool can clear the DTC from the TCM history.
^ The TCM clears the DTC from the TCM history memory after 40 consecutive ignition cycles without fault.
^ The TCM detects the ON signal of the SS 2 monitor during 160 ms when the SS 2 driver outputs the ON signal and the TCM detects the OFF signal of the SS 2 monitor during 160 ms when the SS 2 driver outputs the OFF signal.

Cause of Failure
^ The SS2 and the TCM
^ The SS2
^ The TCM
