The Jaltest JDC562A connects the round 4-pin diagnostic connector of Toyota Material Handling forklift trucks to the 16-pin OBD2 port of your Jaltest diagnostic cable. On the machine side there is a black round plug with a knurled coupling ring and four pin positions; on the interface side there is the flat OBD2 housing. At 30 cm, this is a short adapter that stays close to the connector in the cab.
With the cable connected, the Jaltest software reaches the BC machine computer, the central unit on both the diesel and the electric versions. In addition, the EMS Toyota Denso 1ZS engine control on the diesel trucks and the Zapi TPM drive module with the Zapi PUMP hydraulic control on the electric trucks are covered. What you find depends on the drive type. The cable is covered by Jaltest MHE.
