TEST ACTION APPLICABILITY
1NOTE: Low fluid level can be the cause of many transmission problems. If
the fluid level is low locate and repair the leak then check and adjust the
fluid level per the service information.
NOTE: Always perform diagnostics with a fully charged battery to avoid
false symptoms.
With the DRBIIIt, read the engine DTCs. Check and repair all engine DTCs prior to
performing transmission symptom diagnostics.
With the DRBIIIt, read and record all Transmission DTCs.
NOTE: Check connectors - Clean/repair as necessary. Poor pin to terminal
connections can set DTCs.
Using the wiring diagram/schematic as a guide, inspect the wiring and connectors.
Repair as necessary.
Most DTCs set on start up but some must be set by driving the vehicle such that all
diagnostic monitors have run.
Note: Verify flash level of transmission controller. Some problems are
corrected by software upgrades to the transmission controller.
NOTE: Check for any Technical Service Bulletins that may apply.
Perform this procedure prior to Symptom diagnosis.All

2 With the DRBIIIt, read the active and stored DTCs for all modules that use CAN Bus
communication.
NOTE: Due to capabilities of certain controllers that use the CAN Bus, not
all modules report CAN Bus DTCs.
NOTE: If a total CAN Bus failure transpires, there will be multiple CAN Bus
DTCs present in many modules. If the other modules are reporting Trans-
mission CAN Bus messages ONLY, answer No for the following question.
Are other modules reporting active or stored CAN Bus communication DTCs?All

3 Turn the ignition off to the lock position.
Disconnect the negative battery cable.
While back probing, measure the resistance between the CAN C Bus (+) and the CAN
C Bus (-) in the selected control module harness connector.
NOTE: Termination of the CAN Bus is located in the ECM and SKREEM.
Both modules use a 120.0 ohm resistor for termination of the CAN Bus. A
properly terminated CAN Bus will read 60.0 ohms 5.0 ohms.
Pick the one that best describes your readings:All
60.0 ohms 5.0 ohms.

120.0 ohms 5.0 ohms.

While back probing any module harness connector that uses the CAN Bus, measure
the voltage between the CAN C Bus (+) circuit and ground.

7 Turn the ignition off.
Disconnect the negative battery cable.
Using an ohmmeter, connect one end to the CAN Bus circuit that previously
measured below 50.0 ohms and the other end to ground.
While monitoring the ohmmeter, disconnect a CAN Bus module and record the
reading.
NOTE: Repeat the above step for each CAN Bus module until all the modules
have been disconnected.
NOTE: Refer to the wiring diagrams in the service information to help
determine which modules are on the CAN Bus.
Is the resistance below 50.0 ohms with all the modules disconnected?All
Ye s!Repair the CAN C Bus (+) circuit or the CAN C Bus (-) circuit for
a short to ground.
Perform NAG1 TRANSMISSION VERIFICATION TEST - VER 1.
No!Replace the module that when disconnected, the short to ground
was eliminated.
Perform NAG1 TRANSMISSION VERIFICATION TEST - VER 1.
8 Turn the ignition off.
Disconnect the negative battery cable.
Disconnect the SKREEM harness connector.
Disconnect the ECM harness connectors.
Measure the resistance between the CAN C Bus (+) circuit and the CAN C Bus (-)
circuit.
Is the resistance below 50.0 ohms after disconnecting ECM and SKREEM?All

9 Turn the ignition off.
Disconnect the negative battery cable.
Disconnect the SKREEM harness connector.
Disconnect the ECM harness connectors.
Measure the resistance between the CAN C Bus (+) circuit and the CAN C Bus (-)
circuit at any CAN Bus module harness connector.
Disconnect each CAN Bus module harness connector the vehicle is equipped with,
one at a time, while monitoring the resistance.
NOTE: Refer to the wiring diagrams in the service information to help
determine which modules are on the CAN Bus.
Is the resistance below 50.0 ohms after disconnecting all the modules?All
Ye s!Repair the CAN C Bus (+) circuit for a short to the CAN C Bus (-)
circuit.
Perform NAG1 TRANSMISSION VERIFICATION TEST - VER 1.
No!Replace the module that when disconnected, the short was
eliminated.
Perform NAG1 TRANSMISSION VERIFICATION TEST - VER 1.
