DODGE RAM SRT-10 2006 Service Repair Manual 3.CHECK THE ECM
Disconnect the amp meter from the TIPM C10 harness connector and
battery positive.
Disconnect the ECM C2 harness connector.
Reconnect the positive probe of an ammeter to battery positi

3.CHECK THE ECM
Disconnect the amp meter from the TIPM C10 harness connector and
battery positive.
Disconnect the ECM C2 harness connector.
Reconnect the positive probe of an ammeter to battery positive and
connect the negative probe to the (T16) Transmission Control Output
circuit in the TIPM C10 harness connector.
Read the amperage on the ammeter.
Does the amperage read below 2.0 amps?

Using the schematics as a guide, check the Engine Control
Module (ECM) terminals for corrosion, damage, or terminal
push out. Pay particular attention to all power and ground
circuits. If no problems are found, replace the ECM per the
Service Information. With the scan tool, perform QUICK

4.CHECK THE TRANSMISSION SOLENOIDS
Disconnect the amp meter from theTIPM C10 harness connector.
Disconnect the ECM C2 harness connector.
Connect the positive probe of an ammeter to battery positive and con-
nect the negative probe to the (T16) Transmission Control Output circuit
in the TIPM C10 harness connector.
While monitoring the amperage reading of the ammeter and using a
jumper wire, jump each solenoid control circuit to ground one at a time
in the ECM C2 harness connector.
NOTE: The amperage draw should be approximately .02 milliam-
pere with the PCM C4 harness connector disconnected.
Does the amperage read between .05 and .015 milliampere ±
.005 milliampere on each solenoid tested?
Ye s>>
Replace the Totally Integrated Control Module per the Ser-
vice Information.
Perform RE TRANSMISSION VERIFICATION TEST VER -
1 (DIESEL). (Refer to 21 - TRANSMISSION/TRANSAXLE/
AUTOMATIC - 48RE - STANDARD PROCEDURE)
No>>
Depending on the identified circuit in the test, replace either
Transmission Solenoid/Pressure Switch Assembly per the
Service Information.
Perform RE TRANSMISSION VERIFICATION TEST VER -
1 (DIESEL). (Refer to 21 - TRANSMISSION/TRANSAXLE/
AUTOMATIC - 48RE - STANDARD PROCEDURE)

Turn the ignition off to the lock position.
Connect a 0 to 2068 Kpa or 0 to 300 psi pressure gauge to the Overdrive Clutch Test Port.
Connect a 0 to 2068 Kpa or 0 to 30

7.GOVERNOR PRESSURE SYSTEM TEST
Turn the ignition off to the lock position.
Connect a 0 to 2068 Kpa or 0 to 300 psi pressure gauge to the Overdrive Clutch Test Port.
Connect a 0 to 2068 Kpa or 0 to 300 psi pressure gauge to the Governor Test Port.
Start the engine.
NOTE: Allow the transmission temperature to rise to normal operating temperature.
While observing both pressure gauges, select 4th Gear from Gov and 3-4 System Test.
NOTE: The Governor pressure should rise to above 137.8 Kpa or 20 psi, shortly after the OD pressure
should rise above 275.7 Kpa or 40 psi.
