Second clutch is applied when circuit 1222 is opened at the PCM. When the PCM opens the circuit, the voltage is monitored at terminal J4A07 to check for proper circuit conditions.
DTC P0756 is set when the PCM has detected voltage monitored at terminal J4A07, circuit 1222, is less than 2-2.5 volts when the 2nd gear solenoid is switched OFF electrically by the PCM, twice per ignition cycle.
Numbered steps below refer to numbered steps on the chart.
Monitor the DTC menu Code Status for Pass Since Code Clear and Pass This Ignition Cycle. When both have passed, the repair is verified.
Criteria for pass:
• | The engine is running. |
• | Power is present at the solenoids and no active faults exist for this solenoid. |
This DTC may set or intermittent 2nd gear starts may be caused by a poor electrical connection at either the PCM, solenoid connector plate, or UHJB terminals. Wiggle the connectors while performing an actuator quick test may help isolate the problem area.
When the PCM detects a fault in the circuit, and open, ground, or short, the PCM will open the circuit internally to protect the circuit.
An open will result in 2nd gear being stuck on and a DTC P0741. A grounded circuit 1222 will result in no 2nd gear, no reverse, and a DTC P0732.
