General Information - Diagnostic Trouble Code (DTC) Index Vehicles With:
6HP28 6-Speed Automatic Transmission, DTC: Transmission Control Module
(TCM)
Description and Operation
Transmission Control Module (TCM) 6 speed (6HP28 Applications)
CAUTION: Diagnosis by substitution from a donor vehicle is NOT acceptable. Substitution of control modules does not
guarantee confirmation of a fault, and may also cause additional faults in the vehicle being tested and/or the donor vehicle
NOTES:
If the control module or a component is suspect and the vehicle remains under manufacturer warranty, refer to the
warranty policy and procedures manual, or determine if any prior approval programme is in operation, prior to the installation
of a new module/component
Generic scan tools may not read the codes listed, or may read only 5-digit codes. Match the 5 digits from the scan tool to
the first 5 digits of the 7-digit code listed to identify the fault (the last 2 digits give extra information read by the
manufacturer-approved diagnostic system)
When performing voltage or resistance tests, always use a digital multimeter accurate to three decimal places and with a
current calibration certificate. When testing resistance, always take the resistance of the digital multimeter leads into account
Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests
Inspect connectors for signs of water ingress, and pins for damage and/or corrosion
If diagnostic trouble codes are recorded and, after performing the pinpoint tests, a fault is not present, an intermittent
concern may be the cause. Always check for loose connections and corroded terminals
Where an 'on demand self-test' is referred to, this can be accessed via the 'diagnostic trouble code monitor' tab on the
manufacturers approved diagnostic system
Check DDW for open campaigns. Refer to the corresponding bulletins and SSMs which may be valid for the specific
customer complaint and carry out the recommendations as needed
The table below lists all diagnostic trouble codes (DTCs) that could be logged in the transmission control module, for
additional diagnosis and testing information refer to the relevant diagnosis and testing section
For additional information, refer to: Diagnostics (307-01 Automatic Transmission/Transaxle - V8 5.0L Petrol/V8 S/C 5.0L Petrol,
