ALP 1 No dialogue with the sequential gearbox computer
NOTESSpecial notes:
Only consult this customer complaint after a complete check with the diagnostic
tool.
Use the Wiring Diagrams Technical Note for New TWINGO.
Try to establish dialogue with a computer on another vehicle to make sure that the diagnostic tool is not faulty. If
the tool is not causing the fault and dialogue cannot be established with any other computer on the same vehicle,
it may be that a faulty computer is disrupting the CAN diagnostic line.
Use a process of successive disconnections to locate this computer.
Check the voltage of the battery and carry out the operations necessary to obtain a voltage which is to
specification (9.5 V < battery voltage < 17.5 V).
Check the presence of and condition of the Sequential Gearbox fuses on the passenger compartment fuse box
(7.5 A and 20 A).
Check that the computer connector is properly connected and check the condition of its connections.
Check the sequential gearbox earths (good condition, not corroded, tightness of the earth bolt above the
hydraulic unit).
Check that the supply to the computer is correct:
–Earth on the N connections of the 52-track connector.
–+ AVC on connection BP39 of the 52-track connector.
–+ after ignition feed on connection AP4 of the 52-track connector.
Check that the power supply to the diagnostic socket is correct:
–+ AVC on connection BP19.
–Earth on connections MAM and NAM.
If dialogue has still not been established after these checks, contact the Techline.
AFTER REPAIRClear the computer fault memory. Switch off the ignition and wait 20 seconds.
Carry out a road test followed by another check with the diagnostic tool.
