Transmission Control System Failure. A Combination of Other Errors.

DB9 preliminary diagnostic manual · section 2-162

Manufacturer fault-analysis procedure

Test sequence and decision path

1. Connect the WDS and confirm that P0701 is
logged.

2. Note any other transmission DTCs and resolve
the other DTCs before returning to step 3 of this
procedure if P0701 is logged again after clearing
all DTCs.

3. Run a brief road test. Check if P0701 is logged
again.
If no DTCs are logged, the transmission problem
is resolved. Conduct an extended road test to
ensure system reliability before returning the
vehicle to its owner.
If P0701 is logged again, replace the mechatronic
unit and run a brief road test to ensure that the
problem is resolved.
