Bosch EDC17CP48 Syncro: Volvo

Bosch EDC17CP48 Syncro — for Volvo

Syncro aligns the immobiliser data across the linked modules of a car so that the ECU, the instrument cluster and the ignition lock answer to the same key. Every module on its own may be healthy while the car still refuses to start.

When you need Syncro

• One of the modules was replaced — the new module is not aligned with the rest of the security system.
• After reflashing — the immobiliser data in the unit was overwritten and no longer matches the car.
• Only some modules recognise the key — one module accepts the transponder, another does not.
• Recovery after a failed write — bring the modules back to a common set of immobiliser data.

What you get: every linked module answers to the same key — the engine starts normally.

Bosch EDC17CP48 memory and reading

The Bosch EDC17CP48 unit uses on the TC1797 processor the following: INT FLASH — TC1797, INT EEPROM — TC1797. The Syncro operation works on the INT EEPROM [TC1797] area — that is the one to read out and upload. If OBD reading is not available for this unit, the dump is taken on the bench via Bench or Boot mode.

For the Bosch EDC17CP48 block on the TC1797 processor the «Syncro» operation runs online from the ECU memory dump (access — INT EEPROM [TC1797]). Read the file via OBD, Bench or Boot and upload it — the system detects Bosch EDC17CP48 and checks whether the operation applies for free. You'll get the ready file with recalculated checksums in your portal account.
