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 P---- codes are recieved by connecting a OBDII reader to the computer. You can use the service connect/blinking light method to read the codes (those codes are in parenthesis) however there are not as accurate. Also some codes need to be read twice, some are only for certain models ect. Please contact me for further details regarding such codes*

hey petthepeep...

using the above procedure on my 98RL to get the MIL codes, u gotta watch the blinking MIL light...i got that bit...

but how do u get the ABS ones? does the ABS light blink for that?

and wheres this TCS light? is the procedure for it the same too?

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

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! :bs:

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.

Yes they are from the manual
