ITCARDIAG SM2 PRO ECU Bench Cable with 3 LED Switch, DB25 Pinout

Introducing the ITCARDIAG SM2 PRO+ Bench Cable with Switch, DB25 Pinout — a compact, reliable tool designed for ECU bench testing with SM2 PRO J2534 VCI. This bench cable delivers clear signal routing and intuitive power status right at your workbench, helping you read and write ECUs with confidence.

Built to handle core automotive communication lines, it supports KLINE, CAN-L, CAN-H, GPT1, GPT2 and +VPP, with a precise DB25 pinout. Key connections include Red1: +BATT, Red2: +VCC, Yellow: KLINE, Green: CAN-L, White: CAN-H, Black1: BOOT1, Red: CNF1, Black2: BOOT2, Black3: GND, Orange: GPT2, Purple: +VPP, Brown: GPT1. The trio of LED indicators provides immediate status feedback: Blue for boot/cnf1 power, Red for ACC power, and Green for main power. An external 12V power supply is required to operate the cable safely and effectively.

The SM2 PRO+ bench cable with KLINE support can write older Toyota and Lexus models that use LLINE, expanding your ECU programming capabilities beyond newer vehicles. The integrated power-switch design allows you to control power manually or automatically, helping to prevent power surges and reduce the risk of burning components during bench testing.
