Hi, my SAAB here showing system failure. RED alarm shows SCU Communication system failure. Could you tell me how to fix this error? Thank you in advance.
I am also facing this issue at yesterday, such as a communication error for 1 port pressure sensor and temperature sensor. I have a doubt... during the communication error time in TGU:X1, does the supply voltage come or not between cable 7(red) and cable 8(blue) because pressure sensor supply 7V)
