Diagnostic Test

WARNING: This page is about a different car, the 2007 Chrysler PT Cruiser. However, it is still accessible from the selected car via links, so may be relevant.

1) CHECK TO SEE IF P0706 DTC IS CURRENT
With the scan tool, perform the Shift Lever Position Test.

Select the test outcome from the following:

Test passes:
1. Go to step 6).
Test fails with Error Code:
1. Go to step 2).
Test fails without Error Code:
1. Perform the ADJUSTMENTS procedure per the Service Information.
2. Perform 40/41TE TRANSMISSION VERIFICATION TEST .
2) CHECK THE TRANSMISSION SOLENOID/TRS ASSEMBLY
Turn the ignition off to the lock position.

Remove the Ignition Switch Feed fuse from the TIPM.

CAUTION: Removal of the Ignition Switch Feed fuse from the TIPM will prevent the vehicle from being started in gear.

WARNING: The Ignition Switch Feed fuse must be removed from the TIPM. Failure to do so can result in personal injury or death.

NOTE: Check connectors - Clean/repair as necessary.

Install Transmission Simulator, Miller tool #8333.

Ignition on, engine not running.

With the scan tool, perform the Shift Lever Position Test.

When the scan tool instructs you to put the Gear Selector in a particular position, you must do so using the selector switch on the Transmission Simulator.

The LED for the gear position in question must be illuminated on the Transmission Simulator prior to pressing "ENTER" on the scan tool.

NOTE: If the Shift Lever Position test fails, make sure to note the identification of the TRS Sense circuit for future reference.

Did the Shift Lever Position test pass?

Yes
1. Remove the Oil Pan and Main Valve Body Assembly per the Service Information. Check for metal debris on top of the Solenoid/TRS Assembly and the manual valve code plate. If debris is present, determine the cause of the debris and repair the transmission as necessary. If no problems are found, replace the Transmission Solenoid/TRS Assembly per the Service Information.
2. Perform 40/41TE TRANSMISSION VERIFICATION TEST .
No
1. Go to step 3).
3) TRS SENSE CIRCUIT OPEN
Turn the ignition off to the lock position.

Disconnect the Transmission Simulator, Miller tool #8333.

Disconnect the PCM harness connectors and install Miller tool #8815.

CAUTION: Do not probe the PCM harness connectors. Probing the PCM harness connectors will damage the PCM terminals resulting in poor terminal to pin connection. Install Miller tool #8815 to perform diagnosis.

Measure the resistance of the identified (T1, T3, T41 or T42) TRS Sense circuit between the Transmission Solenoid/TRS Assembly harness connector and the appropriate terminal of Miller tool #8815.

Is the resistance above 5.0 ohms?

Yes
1. Repair the identified (T1, T3, T41 or T42) TRS Sense circuit for an open.
2. Perform 40/41TE TRANSMISSION VERIFICATION TEST .
No
1. Go to step 4).
4) TRS SENSE CIRCUIT SHORT TO GROUND
Measure the resistance between ground and the identified (T1, T3, T41 or T42) TRS Sense circuit.

Is the resistance below 5.0 ohms?

Yes
1. Repair the identified (T1, T3, T41 or T42) TRS Sense circuit for a short to ground.
2. Perform 40/41TE TRANSMISSION VERIFICATION TEST .
No
1. Go to step 5).
5) TRS SENSE CIRCUIT SHORT TO OTHER CIRCUITS
Measure the resistance between the identified (T1, T3, T41 or T42) TRS Sense circuit and all other circuits in the Transmission Solenoid/TRS Assembly harness connector.

Is the resistance below 100k ohms between the identified (T1, T3, T41 or T42) TRS Sense circuit and any other circuit(s) in the Transmission Solenoid/TRS Assembly harness connector?

Yes
1. Repair the identified (T1, T3, T41 or T42) TRS Sense circuit for a short to other circuit(s).
2. Perform 40/41TE TRANSMISSION VERIFICATION TEST .
No
1. Using the schematics as a guide, check the Powertrain Control Module (PCM) terminals for corrosion, damage or terminal push out. Pay particular attention to all power and ground circuits. If no problems are found, replace and program the PCM per the Service Information. With the scan tool, perform QUICK LEARN.
2. Perform 40/41TE TRANSMISSION VERIFICATION TEST .
6) INTERMITTENT WIRING AND CONNECTORS
The conditions necessary to set the DTC are not present at this time.

Using the schematics as a guide, inspect the wiring and connectors specific to this circuit.

Wiggle the wiring and connectors while checking for shorted and open circuits.

With the scan tool, check the DTC EVENT DATA to help identify the conditions in which the DTC was set.

Were there any problems found?

Yes
1. Repair as necessary.
2. Perform 40/41TE TRANSMISSION VERIFICATION TEST .
No
1. Test Complete.
