I need A7 and B2 codes for OBD

RE: I need A7 and B2 codes for OBD
Welcome to the forum,
OBD-I socket A7 is CRZ CTRL. Code 1-2-2:
Speed Below Minimum/No Signal.
Quote from the factory manual: "Code 1-2-2 is stored when ignition is turned on. It remains until vehicle speed is greater than 22 MPH for at least 15 seconds. If code remains after a road test at speeds greater than 22 MPH, control unit is not getting speed signal."
Socket B2 is for instrument: Code 1-2-2:
Temperature Sensor/Interval Too Long.
Wait until other members reply, or buy a Haynes manual for approx $15-$17.
I hope this gets you started.

JPN,
With apologies I would point out that B2 is the cruise control and A7 is the combined instrument. The descriptions are correct but I would add that B2 1-2-2 will always show if the codes are read immediately the ignition is switched on. To do this test the vehicle should be drivenat 22mph + for at least 15 seconds and the codes read before the ignition is switched off. It seems that it was designed to confuse the DIY man.
