Fault-tracing information
The fault should be diagnosed and remedied. Since this is not the case the fault-tracing process has failed.
Complete the fault-tracing for those fault or try again.
Do you want to terminate fault-tracing at this time?
Yes - Exit fault-tracing

Connect an electrician's screwdriver (bulb at least 3 W) between #20 (A#20) and:
#32 (#B2) TC1
#33 (#B3) TC2
#34 (#fB4) TCM
on the breakout box.
The bulb should not light. If the bulb lights there is probably a short-circuit to supply voltage in the circuit.
Is the bulb out?
Yes - Checking signal cables for resistance to ground
No - Checking for a short-circuit
-------------------------------------------------
Checking for a short-circuit
Check cables between transmission control module (TCM):
