Static Testing - Engine OFF

DESCRIPTION
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.

RESISTANCE/CONTINUITY TESTS

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.

NOTE:
- Perform repairs as indicated by the pinpoint tests. Always retest and road test vehicle after a repair.
- Use a volt-ohmmeter to perform the following tests.

EPC Solenoid
1. Set ohmmeter to 100-200 ohm range.
2. Connect the negative lead of the ohmmeter to the EPC jack.
3. Connect the positive lead of the ohmmeter to the VPWR jack.
4. Record resistance.
Solenoid: Resistance
EPC: 3.7-5.92 Ohms
5. If out of range refer to Pinpoint Test E.
Solenoids (SS-1, SS-2, TCC, 3-2 T/CCS)
1. Set ohmmeter to 100-200 ohm range.
2. Connect 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 (SST, SS2, TCC, 3-2T/CCS) jack.
4. Record resistance.
Solenoid: Resistance
SS-1: 12-22 Ohms
SS-2: 12-22 Ohms
TCC: 12.5-19.0 Ohms
3-2 T/CCS: 3.7-5.92
5. If out of range refer to the following pinpoint tests:
Pinpoint Test A: SS1, SS2
Pinpoint Test C: TCC
Pinpoint Test G: 3-2T/CCS
Transmission Fluid Temperature (TFT) Sensor
1. Set ohmmeter to 1000 ohm (K) range.
2. Connect ohmmeter positive lead to +TFT jack.
3. Connect ohmmeter negative lead to-TFT jack.
4. Record resistance. Resistance will vary with temperature.
Fluid Temperature: Resistance
-40 to -20°C (-40 to -4°F): 967-284 K ohms
-19 to -1°C (-3 to 31°F): 284-100 K ohms
0 to 20°C (32 to 68°F): 100-37 K ohms
21 to 40°C (69 to 104°F): 37-16 K ohms
41 to 70°C (105 to 158°F): 16-5 K ohms
71 to 90°C (159 to 194°F): 5-2.7 K ohms
91 to 110°C (195 to 230°F): 2.7-1.5 K ohms
111 to 130°C (231 to 266°F): 1.5-0.8 K ohms
131 to 150°C (267 to 302°F): 0.8-054 K ohms
5. If out of range refer to Pinpoint Test B.
Turbine Shaft Speed (TSS) Sensor
1. Set ohmmeter to 1000 ohms (K) range.
2. Connect the positive lead of the ohmmeter to the +TSS jack.
3. Connect the negative lead of the ohmmeter to the-TSS jack.
4. Record the resistance.
5. TSS should be 140-290 ohms. If out of range refer to Pinpoint Test F.

SOLENOID VOLTAGE TEST
1. Tester BENCH/DRIVE switch set to BENCH mode.
2. Set voltmeter to 20 volt D.C. range.
3. Connect voltmeter positive lead to the appropriate solenoid VPWR, connect voltmeter negative lead to the appropriate solenoid. Using a VOM, check for voltage across each solenoid by activating the solenoid switches. 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.

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.

4. Observe and record values.
