TCU Codes (Automatic Transmissions) DSMs коды ошибок акпп
Here are the codes for the TCU. These can be obtained by using the same principal for pulling the ECU codes.
I use a multimeter and 2 wires with alligator clips. You can get the clips from Radio Shack or wherever.
Hook up to pins and Set the mulitmeter for 12 V. Turn the key all the way but do not crank (the power windows work in this position). Watch the pulses of the needle (if Analog). Write down L for long and S for short. The TCU will cycle the codes over and over. So you can double check them if needed. If you get constant short pulses, the TCU has no codes and all is well (so it would seem).
Once you write it down, figure L = 10 and S = 1. EX: L-L-S-S=22. GO to the chart below and it will tell you what the code means.
The left is the 1G Diagnostic plug. The right is the 2G.
Red is you hook up the Positive lead of the Meter and Gray is Negative. If it does not work or read, try reversing the leads.
1G hook POS to #6 and NEG to #12.>>>>>>>>>>>>>> 2G POs to #6 and NEG to #4.11 Excessive Large TPS (Throttle Position Sensor) output.
