help regarding ECU code

joey · Post by **joey** » Thu Nov 10, 2005 10:11 pm

can any help me to find out what this code mean
SCI fail
SCI relay fail
DCC system fail

this morning i had my fisrt service on the car since i brouight it one month ago

What are the error codes?

joey · Post by **joey** » Thu Nov 10, 2005 10:40 pm

thats the only information i have
but all these codes came from the transmision side

do you know what SCI and DCC stands for,
couldnt find anything in the manual

i think it means their computer is not communicating with the ECU

i got the the error code
51 and 52 on the transmission side
can anyone help finding out what is this code mean

is that a big repair
cost wise

I think those are engine codes, the transmission ones are different IIRC

Post by **Bennoz** » Fri Nov 11, 2005 1:33 pm

Hmmm I'll have to dig up the tranny ones...

joey · Post by **joey** » Fri Nov 11, 2005 1:34 pm

what is code for the transmission

RedlineGX · Post by **RedlineGX** » Fri Nov 11, 2005 3:09 pm

Do you mean how do you read the codes? IIRC the Neutral light flashes just as the engine light and ABS lights would flash their codes.

joey · Post by **joey** » Fri Nov 11, 2005 4:45 pm

yes

i need to find out what is the code for 51 and 52 on the transmision side

Post by **Bennoz** » Sat Nov 12, 2005 12:43 pm

Ok, found em...

Automatic transmission - Chassis manual section 23

With a flashing N lamp there are two possibilities of what it could be.

If it flashes at 1Hz, once a second, then it will be either,

Input speed sensor
Output speed sensor
Solenoid valve
Out of phase at shift points
A/T control relay system

If it flashes at 2Hz, twice per second, the ATF temperature is too high and you should stop to allow it to cool down.

11, 12 and 14 all relate to Throttle position sensor system (Vehicles without TCL) and Accelerator pedal position sensor system (Vehicles with TCL)
Code
11 Short circuit
12 Open circuit
14 Sensor maladjustment
15 Oil temp sensor system Open circuit
21 Crank angle sensor system Open circuit
22 Input shaft speed sensor Open/Closed circuit
23 Output shaft speed sensor Open/Closed circuit
26 Stop lamp switch system Short circuit
31 Low and reverse solenoid valve system Open/Closed circuit
32 Under drive solenoid valve system Open/Closed circuit
33 Second solenoid valve system Open/Closed circuit
34 Overdrive solenoid valve system Open/Closed circuit
35 Reduction solenoid valve system Open/Closed circuit
36 Damper control clutch solenoid valve system Open/Closed circuit
41 1st gear ratio does not meet specification
42 2nd gear ratio does not meet specification
43 3rd gear ratio does not meet specification
44 4th gear ratio does not meet specification
45 5th gear ratio does not meet specification
46 Reverse gear ratio does not meet specification
51 Abnormal communication with Engine ECU or Abnormal communication with TCT ECU
52 Damper control clutch solenoid valve system Defective system
54 A/T control relay system Short circuit to earth/ open circuit
56 N range lamp systems Short circuit to earth
71 Malfunction of A/T ECU

51 Abnormal communication with Engine ECU or Abnormal communication with TCT ECU
52 Damper control clutch solenoid valve system Defective system

Unfortunately I know very little about the tips - being a manual owner. But it sounds like that shot soleniod would cause the communication error. Then again, it could be something as simple as a ripped wire... you bottomed out on anything lately?

Take off your panels and have a look at the tip ecu to make sure everything is plugged in ok and clean. My coolant from the heater matrix had a leak, dripped on my ecu and had my tip box playing up fro a while before i figured out what it was.

thank you for the information i'm very greatful
i have reset the ECU yesterday and cleared the error code and drove it around all day the error code didn't not show up agian but if it does it agian i will check on the wiring on the A/t to the ECU

just cause it clears the error code doesnt mean the problem is fixed

jonowong · Post by **jonowong** » Sun Nov 13, 2005 8:14 pm

resetting prob made it forget theres a prob

joey · Post by **joey** » Mon Nov 14, 2005 9:25 am

i'll check the wiring tonight thank you for that

but can any one tell me Error code 51 52 55 what does it mean ?
