Static Testing - Engine OFF

DESCRIPTION
Static testing procedures allow for shop testing of the transmission in the vehicle or on the bench. Completion of these tests prove out transmission electronics.

CAUTION: For resistance checks, be sure the tester Solenoid Select switch is set to the OHMS CHECK position or damage to the ohmmeter may result.

RESISTANCE/CONTINUITY TESTS
EPC Solenoid
- Set ohmmeter to 100-200 ohm range.
- Connect negative lead of ohmmeter to the EPC jack.
- Connect positive lead of ohmmeter to the VPWR jack.
- Record resistance.
- Refer to the following charts for values. If out of specification, refer to Pinpoint Test E.

Solenoids (SS-1, SS-2, TCC)
- Set ohmmeter to 100-200 ohm range.
- Connect positive lead of ohmmeter to the appropriate VPWR jack for the solenoid being tested.
- Connect negative lead of the ohmmeter to the appropriate solenoid jack (SS-1, SS-2, MCCC) and record resistance.
- Refer to the following charts for values. If out of specification, refer to Pinpoint Test A (SS-1,SS-2); Pinpoint Test C (TCC).
Solenoid
SS-1: 20-30 Ohms
SS-2: 20-30 Ohms
TCC: 10-16 Ohms
EPC: 2.48-5.66 Ohms
Transmission Fluid Temperature (TFT) Sensor
- Set ohmmeter to 1000 ohm scale.
- Connect ohmmeter positive lead to +TOT jack.
- Connect ohmmeter negative lead to -TOT jack.
- Record resistance. Resistance will vary with temperature.
- Refer to the following chart.
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
If out of specification, refer to Pinpoint Test B. B: Transmission Fluid/Oil Temperature (TFT/TOT) Sensor
Output Shaft Speed Sensor (OSS)
- Set ohmmeter to 1000 ohm (K) range.
- Connect the positive lead of the ohmmeter to the +OSS.
- Connect the negative lead of the ohmmeter to the-OSS.
- Record resistance.
- OSS should be 450-750 ohms.
If out of specification, refer to Pinpoint Test F.





SOLENOID VOLTAGE TEST
1. Slide MODE switch to BENCH.
2. Set voltmeter to 20 volt D.C.
3. Determine the solenoid you wish to test and connect the voltmeter lead as follows:
- If testing SS 1, SS2 or SS3 solenoid, turn the SOLENOID SELECT dial to SS 1, SS2 or SS3 before hooking up leads. If testing EPC or TCC solenoids, continue.
- Connect the negative lead to the appropriate solenoid jack.
- Connect the positive lead to the appropriate VPWR jack.
4. Press the solenoid's ACTIVATE/DEACTIVATE button and check voltage. The LED should light, the voltage should change and an audible click may be heard. See LED status for reading LED status.
5. Observe and record values.
LED status:
LED turns green when solenoid activates and OFF when deactivated.
LED turns red if an activated solenoid/harness is shorted to B+.
LED remains off if an activated solenoid/harness is shorted to ground or no continuity.
