Discussion:
Codes E03 and P03

Hello everyone,
I am working on a Nissan UniCarriers mcp1f2a25lv truck which has communication problems with the VCM error codes E-03 and P-03. The truck won't start, move or lift. I can bypass the staring circuit and the engine runs great but the truck won't travel and all hydraulics are disabled. 20A VCM fuse checked good, however I suspect no power to the VCM.
Can someone provide pinout for VCM 29310gg20b or wiring diagram or color code on the wires connected to the VCM?
Your help is much appreciated.

Fact of the week
In March 2002, identical twins in Finland died on the same day in similar accidents within hours of each other. A 70-year-old man was killed by a truck while cycling; hours later, his twin brother was killed by a truck on the same road, about a mile away, before the family had been informed of the first accident.
