Static Testing

STATIC TESTING-VEHICLE "OFF"
Static testing procedures allow for shop testing of the transaxle in the vehicle or on the bench. Completion of these tests prove out the transaxle electronically.

CAUTION: For resistance checks, be sure that the tester solenoid select switch is set to the "OHMS CHECK" position or damage to the ohmmeter may result.

Resistance/Continuity Tests
1. Refer to Pinpoint Test to be performed "On Board Diagnostics" based on the DTC displayed.




2. Using a volt-ohmmeter and the transaxle tester, perform the Pinpoint Tests as indicated in "On Board Diagnostics" based on the DTC which were displayed.
3. Perform repairs as indicated by the Pinpoint Tests. Always retest and road test the vehicle after a repair.

Transaxle Solenoid And Sensors Resistance Tests

Solenoids (EPC, SS1,SS2, TCC, 3-2T/CCS)
1. Set an ohmmeter to the 0-100 ohm range.
2. Conned the positive lead of the ohmmeter to the appropriate VPWR jack for the solenoid being tested.
3. Connect the negative lead of the ohmmeter to the appropriate solenoid (EPC, SS1, SS2, TCC, 3-2T/CCS) jack.
4. Record the resistance.




5. Refer to the chart for the valves.

6. If out of range refer to the following pinpoint tests.
- Pinpoint test E (EPC)
- Pinpoint test A (SS1, SS2)
- Pinpoint test C (TCC)
- Pinpoint test G (3-2T/CCS)

Transaxle Fluid Temperature (TFT)
1. Set an ohmmeter to the 1,000 ohm range.




2. Connect the positive lead to the + TFT jack.
3. Connect the negative lead to the - TFT jack.
4. Record the resistance. Resistance will vary with temperature.




5. Refer to the chart for the valves.
6. If out of range, refer to Pinpoint test BA, BB, BC, BD, BE, BF.

Turbine Shaft Speed (TSS) Sensor
1. Set an ohmmeter to the 1,000 ohm range.




2. Connect the positive lead to the +TSS jack.
3. Connect the negative lead to the -TSS jack.
4. Record the resistance.
5. TSS should be 140-290 ohm.
6. If out of range, refer to Pinpoint test F.

Short To Ground And Solenoid Voltage Tests




NOTE: LED will turn "GREEN" when solenoid activates and turn OFF" when deactivated. LED will turn "RED" if an activated solenoid/harness is shorted to BAT+. LED will remain "OFF" if an activated solenoid/harness is shorted to ground or no continuity.

1. Tester Bench/Drive switch set to "BENCH" mode.
2. Set an voltmeter to the 20 volt D.C. range.




3. Connect the voltmeter positive lead to the appropriate solenoid VPWR.
4. Connect voltmeter negative lead to the appropriate solenoid.
5. Using the voltmeter, check for voltage across each solenoid by activating the solenoid switch. Select the appropriate solenoid with the rotary switch and depress the corresponding solenoid switch. The "LED" should illuminate, the voltage should change, and an audible click may be heard. If "LED" does not illuminate, a short to ground condition exists.
6. Observe and record the values.
