STEP-BY-STEP BENCH CONNECTION PROTOCOL (HOWTO)BENCH / BOOT
- Step 1 (Terminal 30 & Terminal 15 power): Apply stabilized
13.5V — 13.8Vto the permanent power (T30) and ignition (T15) pins, plus ground (GND), following the cable color coding above. - Step 2 (CAN bus & GPT0 / GPT1 generator lines): Connect the
CAN-HandCAN-L, plus the signal wiresGPT0 (S1)andGPT1 (S2)to enter service mode without opening the ECU case. - Step 3 (Full PFLASH + DFLASH backup read): Before any write operation, read and save a full backup of the internal flash (
PFLASH) and the EEPROM area (DFLASH).
