Codes d'erreur TCU TurboLamik : référence complète et points à contrôler
TurboLamik error codes split into three practical blocks, and the block tells you where to look first. Everything above 110 is a mechatronics code, so the fault sits in the valve body, its solenoids or the harness feeding them. The 001 to 009 codes are open circuits on individual solenoid outputs. The 61 to 104 block is internal controller health and is usually heat related. Codes 13, 33 and 105 are power, CAN and software mismatches.
Group the code before you touch anything. A mechatronics resistance fault will not be found by swapping CAN L and CAN H, and a CAN fault will not be found by measuring solenoid resistance.
How the numbering works
The manual gives one shortcut that does most of the sorting for you: check errors higher than 110 under mechatronics errors. That single line divides every code into electrical faults inside the gearbox (above 110) and everything else (below 110).
| Code range | Category in the manual | Where the fault usually sits |
|---|---|---|
| 001 to 009 | Solenoid output, open circuit | Mechatronic soldering, harness, plug pins |
| 13 | Power ground not connected | TCU power ground wiring |
| 33 | No communication with the motor controller | CAN wiring, pin connectors, CAN standard |
| 61 to 104 (listed individually) | Internal malfunction | TCU internal temperature |
| 105 | Maps newer than the driver software | Map version against driver version |
| 110 and above | Mechatronics errors | Valve body, solenoids, internal wiring |
Power, CAN and software codes
These three codes are the ones you can often clear without opening the gearbox.
| Code | Meaning in the manual | What to check first |
|---|---|---|
| 13 | Power ground not connected | Check the ground path. In parameters, the "Ground differential voltage" value cannot be greater than 2V |
| 33 | The TCU does not communicate with the selected motor controller | CAN L and CAN H are wired correctly, try swapping them to test, look for a faulty pin connector, confirm the CAN bus communication standard selected matches the device |
| 105 | The loaded maps are a newer version than the driver software | Use older maps, or update the driver to a newer software version |
Error code 33 is worth treating as a wiring and configuration check rather than a hardware failure. The manual lists the likely causes in order: incorrect CAN L and CAN H connection, a faulty pin connector, and the wrong CAN bus standard selected. Work through all three before assuming the controller is at fault.
What the 61 to 104 block means
The manual names this block explicitly: codes 61, 62, 63, 64, 65, 66, 67, 68, 71, 72, 78, 81, 82, 88, 91, 92, 98, 101, 102, 103 and 104. These are internal malfunctions of the controller and may result from the device running too hot. If letting the driver cool down does not clear the fault, the manual directs the owner to the manufacturer.
Do not chase a solenoid or wiring explanation for a code in this list. It is a controller temperature and health message, not a gearbox message.
Solenoid open circuit codes: 001 to 009
Codes 001 to 009 are the "no connection" group. Each one maps to one solenoid output on the mechatronics unit.
| Code | Output | Fault |
|---|---|---|
| 001 | Out1 | No connection, open circuit |
| 002 | Out2 | No connection, open circuit |
| 003 | Out3 | No connection, open circuit |
| 004 | Out4 | No connection, open circuit |
| 005 | Out5 | No connection, open circuit |
| 006 | Out6 | No connection, open circuit |
| 007 | Out7 | No connection, open circuit |
| 008 | Out8 | No connection, open circuit |
| 009 | Out9 | No connection, open circuit |
The manual's diagnostic note for this group is specific. These codes are commonly caused by a damaged harness, damaged 8HP gearbox pins, or damaged TCU plug pins, because the problem is usually the connection rather than the solenoid itself. Check the connections between the 8HP plug and the TCU, confirm the pins actually make contact, and confirm they are plugged into the correct pins. If that does not solve it, the next suspect is bad PCB or wire soldering inside the mechatronic unit.
Mechatronic codes above 110
Above 110 the codes describe what the controller measures across each solenoid output. Each output has three failure modes: resistance too high, resistance too low, and short to ground. The numbers follow a repeating pattern, which makes them easier to read as a block.
| Output | Resistance too high | Resistance too low | Short to ground |
|---|---|---|---|
| Solenoid 1 | 112 | 113, 114 | 116, 117 |
| Solenoid 2 | 122 | 123, 124 | 126, 127 |
| Solenoid 3 | 132 | 133, 134 | 136, 137 |
| Solenoid 4 | 142 | 143, 144 | 146, 147 |
| Solenoid 5 | 152 | 153, 154 | 156, 157 |
| Solenoid 6 | 162 | 163, 164 | 166, 167 |
| Solenoid 7 | 172 | 173, 174 | 176, 177 |
| Solenoid 8 | 182 | 183, 184 | 186, 187 |
| Solenoid 9 | 192 | 193, 194 | 196, 197 |
Some codes are shared diagnostics, meaning one code covers two adjacent solenoids and cannot tell you which of the pair is at fault:
| Shared code | Covers |
|---|---|
| 118, 128 | Solenoid 1 or solenoid 2 |
| 138, 148 | Solenoid 3 or solenoid 4 |
| 158, 168 | Solenoid 5 or solenoid 6 |
| 188, 198 | Solenoid 8 or solenoid 9 |
When you get a shared diagnostic, you cannot trust the code to name the solenoid. You have to test both outputs in the pair.
Solenoid resistance reference values
The manual publishes expected resistance for each solenoid. Measure and compare rather than guessing at resistance deviation codes.
| Solenoid | Expected resistance |
|---|---|
| Solenoid 1 | 5.5 Ω |
| Solenoid 2 | 5.5 Ω |
| Solenoid 3 | 5.5 Ω |
| Solenoid 4 | 5.5 Ω |
| Solenoid 5 | 5.5 Ω |
| Solenoid 6 | 5.5 Ω |
| Solenoid 7 | 5.5 Ω |
| Solenoid 8 | 10 Ω |
| Solenoid 9 | 25 Ω |
Note that solenoids 8 and 9 are not the same family as the first seven. Solenoid 8 sits at 10 Ω and solenoid 9 at 25 Ω, so a rough "all solenoids are about 5.5 Ω" rule will send you the wrong way on the last two outputs.
Insulation faults: the 1x6, 1x7 and 1x8 codes
The manual gives a different test for these. Measure resistance between the case and any pin of the 8HP plug. The meter should read infinity, or at least higher than 1 MΩ. A reading below 1 MΩ may cause errors 1x6, 1x7 and 1x8, where x is the solenoid number.
The manual states the reason is most often impurities inside the case. That is a different failure mode to a resistance deviation or an open circuit, and it needs a different repair path.
A sensible test order
- Read the code and put it in one of the three blocks: below 110, above 110, or the 61 to 104 internal list.
- For a below 110 code, work power, CAN and software first. Code 13 is a ground check, code 33 is a CAN and connector check, code 105 is a map and driver check.
- For an open circuit code (001 to 009), inspect the harness, the 8HP gearbox pins and the TCU plug pins before condemning a solenoid.
- For a resistance or short code (110 and above), measure solenoid resistance against the reference table and treat shared diagnostics as two suspects.
- For insulation codes, test case to pin and expect infinity or more than 1 MΩ.
Frequently asked questions
What does "check errors higher than 110" mean? It is the manual's way of splitting the code list. Codes above 110 are mechatronics errors, so the fault relates to the valve body, its solenoids or the internal wiring. Codes below 110 cover power, sensors, CAN and internal controller health.
Is error code 33 always a wiring problem? Not always, but the manual points there first. The stated causes are incorrect CAN L and CAN H connection, a faulty pin connector, and the wrong CAN bus communication standard selected. Work through those before replacing hardware.
Why do codes 118 and 128 appear together? They are common diagnostics. Code 118 or 128 means a short to ground on solenoid 1 or solenoid 2, and the code alone cannot tell you which one.
What resistance should TurboLamik solenoids measure? Solenoids 1 to 7 measure 5.5 Ω. Solenoid 8 measures 10 Ω. Solenoid 9 measures 25 Ω.
What causes the 1x6, 1x7 and 1x8 errors? A case to pin resistance below 1 MΩ. The manual notes the cause is most often impurities inside the case. With no fault, the meter should read infinity or above 1 MΩ.
Can I clear a 61 to 104 code myself? The manual says this block may come from the device running too hot and suggests letting it cool down. If cooling does not clear it, the manual directs you to the manufacturer.
