DTC Codes for Acura RL

I have gone through the serice manual and listed the DTC codes for the RL. These codes give a pretty good idea about what needs to be troubleshooted. For each code, there is about a page of flowcharts to diagnose the problem correctly. Feel free to contact me whenever a code pops up to figure out what needs to be done.

To read the codes, insert the service connector or the 2 ends of a wire into the 2 slots in the blue connector under the glove compartment. Turn the ignition to ON(II). The light will come on for 2 seconds. This is the test phases, do not count this inital one. After the light goes out, start counting the blinks. It will be long ones followed by short ones. (i.e. 3 long blinks and 5 short ones is a code 3-5) Sometimes you may have more than one code stored in the memory. The first code that blinks is the most recent. The ECU will store up to 3 codes for each light.

The TCS light, on the display, is located directly below the ABS light under the Water Temp Gauge. The procedure is the same to read the codes of each light. The ABS light blinks ABS codes, TCS blinks TCS codes ect.

ok i just checked this and guess what: I GOT NO TCS LIGHT!!

right under the ABS light is the seatbelt indicator, and parallel to the ABS light is the SRS light, and under that is the FUEL light...

...but no TCS light

do these even come without TCS? i thought it was supposed to be standard! damn these double-standards!

I tried to get the abs code on my grandma's 97 RL and I get one longer flash three times but no faster flashes. I called my local dealer and he said that you cannot check the abs codes through jumping that blue plug. Any help or ideas? Is it the pump motor over run? Help...

I realize this was from awhile ago, but hopefully you can help me out. My car pulled the code 'P1318, Spark Plug Voltage Detection Module Reset Circuit Malfunction, Front Bank' and I need help on what to check. Any help you can give would be greatly appreciated.

Received code 10-1 for SRS: "SRS replacement code".

I'll go ahead and ask the stupid question. "Must i replace the SRS unit or is this referring to something else?"

FWIW, tried 5x and cannot get the SRS light to reset via the driver-side connector.
