Solenoid Testing Procedure
| Callout | Component Name |
|---|---|
| 1 | Regulated Air Supply |
| 2 | Test Ports |
| 3 | Scan Tool |
| 4 | Test Pressure Gauge |
| 5 | Electrical Connector Sleeve |
- Align and install the electrical connector sleeve to the control solenoid valve assembly and secure with the connector slide lock.
- If necessary, clean each side of the filter plate assembly and install the filter plate assembly back on the control solenoid valve assembly. Clean the mounting surface of the DT-47825 control solenoid test plate.
- Bolt the DT-47825 control solenoid test plate to the control solenoid valve assembly mounting surface. Use the bolts and washers supplied with the tool to attach the test block. Tighten the bolts to 5 N.m (44 lb in).
- Connect the test harness supplied with the DT-47825 control solenoid test plate to the vehicle harness and to the TCM. Engage the connector locks.
- Connect shop air to the DT-47825 control solenoid test plate air inlet. Do not exceed the recommended air pressure of 620.5-689.4 Kpa (90-100 psi).
- Connect the test pressure gauge to the test port for the solenoid to be tested.
- With the ignition ON and the scan tool communicating with the vehicle, command the solenoid to be tested ON and OFF. Watch the air pressure gauge for a change as you command the solenoid. Refer to Control Solenoid Valve Assembly Solenoid Performance Test Plate to Component Identification for correct solenoid function and test plate port connections for the solenoid being tested.
- The solenoid should allow air pressure to flow when commanded ON and prevent air pressure flow when commanded OFF. The test results are read on the pressure gauge.
- Command the solenoid valve ON and OFF several times to determine the condition of the solenoid in question. Release the test air pressure from the pressure gauge between solenoid tests.
CAUTION:
Do not probe any circuit with a multi-meter. Resistance tests across the serial data bus circuits will damage the TCM.
CAUTION:
The TCM connector sleeve allows the test tool harness to be correctly orientated for electrical operation of the TCM. Do not connect the test harness to the TCM without using the connector sleeve. Failure to use the sleeve could allow the test harness to be incorrectly positioned which will result in permanent TCM damage.
