C101 Pin 17 - RED/WHT - Any ideas?

Post by Muu »

Hi

Have searched, read docs, looked in Hondata FAQ and still can't figure out what pin 17 does on the C101.

It has two red/wht cables on the one pin, and FYI this is a UK spec (PRA) loom and ECU.

Any help much appreciated.

C101 is on the dash loom with the E plug, and hooks into the engine loom along side the A&B plug.

Also wondering what pin 2 (yellow) does too!

Ok, I have two manuals, i guess one is the newer, connector C101 is the C145 connector. . .colors remain the same.

you will have to do some testing because the older manual is not as clear, but i suspect what the pins are below

pin 17 is red\wht: headlights - chk see if you are getting voltage on/off at this pin while turning on/off the headlight
pin 2 is yellow: ecu communication with multiplex - think its 5v with ign on

Yellow is multiplex but on the E8 plug, the C101 is all the chassis to engine connections.

Ok from reading a tracing the loom, C101/17 looks to be ECT feed for the dash (it loops off the C101 up to the E, hence two cables)

Pin 2 Yellow, is the 12v feed for the back up switch.

(long day!)
