## DTC P0758 Non European or 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 hold lamp 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

Normal | SS2 Fail
--- | ---
Gear | SS1 | SS2 | Gear | SS1 | SS2
1st | ON | ON | 2nd | ON | FAIL
2nd | ON | OFF | 2nd | ON | FAIL
3rd | OFF | OFF | 3rd | OFF | FAIL
4th | OFF | ON | 3rd | OFF | FAIL

### Conditions for Clearing the DTC

• | The TCM turns OFF the hold lamp 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.
