P0761

Diagnostic Chart:

Diagnostic Chart (cont'd):

Wiring Diagram:

3rd clutch is applied when circuit 1223 is opened at the PCM. When the PCM opens the circuit the voltage is monitored at terminal J4A06 to check for proper circuit conditions.

DTC PARAMETERS

DTC P0761 is set when the PCM has detected the following condition twice per ignition cycle.

- Voltage monitored at terminal J4A06 (circuit 1223) is below 2 - 2.5 volts when the 3rd gear actuator is switched off electrically by the PCM.

TEST DESCRIPTION

Numbered steps below refer to numbered steps on chart.

1. This step verifies problem is still present.

2. If the TRS 3/4 fuse is ok, check for battery voltage on fuel pump relay side of fuse with engine running.

3. This step checks for a ground in circuit 1527. A ground in circuit 1527 will cause the TRS 3/4 fuse to fail and DTC P0761.

4. An open in circuit 1527 will cause DTC P0761 to set. Check circuit 1527 for opens.

5. This step will determine if a fault is in the circuit to the PCM or in the actuator or connector plate.

6. This step will determine if the fault is in the actuator or the connector plate.

7. An open or a ground in circuit 1223 will set DTC P0761. This step checks circuit 1223 for opens or grounds.

REPAIR VERIFICATION

Monitor DTC menu "Code Status" for "Pass Since Code Clear" and "Pass This Ignition Cycle." When both have passed, repair is verified.

Criteria for pass:

- Engine running.

- Power present at actuators and no active faults exist for this actuator.

DIAGNOSTIC AIDS

When attempting to diagnose an intermittent problem use the Scan tool* to review supplemental diagnostic information. The supplemental data can be used to duplicate a problem.

* Select MALF History and DTC status from DTC menu of Scan tool.

- This DTC may set or intermittent 3rd gear starts may be caused by a poor electrical connection at either the PCM, actuator connector plate or Under Hood Junction Block (UHJB) terminals. Wiggling connectors while performing an actuator quick test may help isolate the problem area.

Check the tightness of the female terminal grip with a spare male terminal.

When the PCM detects a fault in the circuit (open, ground, short) the PCM will open the circuit internally to protect the circuit.

- An open circuit will probably result in a DTC P0782 3rd gear stuck on, DTC P0732 no 2nd gear, and DTC P0741 - No TCC, while a grounded circuit will result in a no 3rd gear/DTC P0733, and P0732 no 2nd gear.

- When condition (open circuit) is present 3rd gear starts will occur.
