ALP1 No dialogue with the ABS/ESP computer
NOTESOnly address this customer complaint after a complete check with the diagnostic tool.
Use the Wiring Diagram Technical Note for New Twingo.
Try to establish dialogue with an ESP computer on another vehicle to make sure that the diagnostic tool is not
faulty. If the tool is not at fault, and dialogue cannot be established with any other computer on the same vehicle,
the cause could be a faulty computer interfering on the multiplex network.
Check the tightness and condition of the battery terminals (see 80A, Battery).
Check the charging circuit (see 16A, Starting - Charging).
Check that the power supply to the diagnostic socket is correct:
Check for + 12 V on connection BP19 of component 225.
Check for earth on connections MAM and NAM of component 225.
If the connections are faulty (see Technical Note 6015A, Repairing electrical wiring, Wiring: Precautions for
repair), repair the wiring, otherwise replace it.
Apply the fault finding procedure for specification 1. DEF of fault DF001 Computer supply.
Carry out fault finding on the multiplex network using the diagnostic tool (see 88B, Multiplexing).
If dialogue has still not been established after these checks, contact Techline.
