Test Description
WARNING: This page is about a different car, the 2003 Saturn LW300, 2003 Saturn LW200, 2003 Saturn L300, and 2003 Saturn L200. However, it is still accessible from the selected car via links, so may be relevant.
The numbers below refer to the step numbers on the diagnostic table.
- 5: By disconnecting the TR switch, the ground path for all TR switch circuits would be removed and the PCM should recognize all circuits as open. The scan tool should display HI for all range signals.
- 6: This step tests the TR switch wiring for an open or lack of signal voltage from the PCM.
- 7: This step tests the TR switch wiring and the PCM by providing a ground path through a fused jumper wire. When grounded, the scan tool range signal A should change to LOW.
- 8: This step tests the TR switch wiring and the PCM by providing a ground path through a fused jumper wire. When grounded, the scan tool range signal B should change to LOW.
- 9: This step tests the TR switch wiring and the PCM by providing a ground path through a fused jumper wire. When grounded, the scan tool range signal C should change to LOW.
DTC P0705 (2.2L (L61))

10-12 V | Go to Step 8 | Go to Step 12 |
| 8 | Connect a fused jumper wire from terminal D of the TR switch 4-way connector, signal A circuit, to ground while monitoring the scan tool TR Switch - P/A/B/C parameter. When the signal A circuit is grounded, do any other signal circuits indicate LOW? |
- | Go to Step 13 | Go to Step 9 |
| 9 | Connect a fused jumper wire from terminal B of the TR switch 4-way connector, signal B circuit, to ground while monitoring the scan tool TR Switch - P/A/B/C parameter. When the signal B circuit is grounded, do any other signal circuits indicate LOW? |
- | Go to Step 13 | Go to Step 10 |
| 10 | Connect a fused jumper wire from terminal C of the TR switch 4-way connector, signal C circuit, to ground while monitoring the scan tool TR Switch- P/A/B/C parameter. When the signal C circuit is grounded, do any other signal circuits indicate LOW? |
- | Go to Step 13 | Go to Step 16 |
| 11 | Test the signal circuits of the TR switch that did not indicate HI for a short to ground. Refer to Testing for Short to Ground and Wiring Repairs in Wiring Systems. Did you find and correct the condition? |
- | Go to Step 18 | Go to Step 17 |
| 12 | Test the signal circuits of the TR switch that did not indicate proper voltage for an open. Refer to Testing for Continuity and Wiring Repairs in Wiring Systems. Did you find and correct the condition? |
- | Go to Step 18 | Go to Step 17 |
| 13 | Test the affected signal circuits of the TR switch for a shorted together condition. Refer to Circuit Testing and Wiring Repairs in Wiring Systems. Did you find and correct the condition? |
- | Go to Step 18 | Go to Step 17 |
| 14 | Test the ground circuit of the TR switch for an open. Refer to Testing for Continuity and Wiring Repairs in Wiring Systems. Did you find and correct the condition? |
- | Go to Step 18 | Go to Step 16 |
| 15 | Replace the electronic PRNDL module. Refer to Shift Indicator Replacement
. Did you complete the replacement? |
- | Go to Step 18 | - |
| 16 | Replace the TR switch. The TR switch is part of the park/neutral position switch. Refer to Park/Neutral Position (PNP) Switch Replacement . Did you complete the replacement? |
- | Go to Step 18 | - |
| 17 | Replace the PCM. Refer to POWERTRAIN CONTROL MODULE in Removal & Installation. Did you complete the replacement? |
- | Go to Step 18 | - |
| 18 | Perform the following procedure in order to verify the repair:
Has the test run and passed? |
- | Go to Step 19 | Go to Step 2 |
| 19 | With the scan tool, observe the stored information, capture info and DTC info. Does the scan tool display any DTCs that you have not diagnosed? |
- | Go to DIAGNOSTIC TESTS in Self-Diagnostics - 2.2L or DIAGNOSTIC TESTS in Self-Diagnostics - 3.0L | System OK |
