Car idles fine for around 30 sec. then ASR light comes on and car drops severely in idle and function. What are these codes pointing to?

Pin 4- 4

Pin 6- 10,11,30

Pin 7- 3,5,6,14

Pin 8- 5,6,12

I erased all codes, except on pin 4 I couldn't get it to clear. I restarted the car for a while and let it run. When I retested I had codes

Pin 6- 10 and Pin 7- 14. these two codes had already reappeared. My ASR light never went off even after resetting all the codes. All help is very appreciated.

Pin # 7 is the cause of the ASR lamp.
Code 3, is pointing to the throttle actuator.
Code 5, is for a bad brake lamp switch.
Code 6, is for a bad neutral safety switch.
Code 14, is about mis-adjusted accelerator cable OR bad switch on the gas pedal.

Wow, you've hit the jackpot. Every single one of those will send a car into "limp home". My car is the poster boy for this problem (still unsolved)

Here's the codes in "module" format . . "pins" confuse me ..


Module - Pin - Code# - Description
LH-SFI -- 4 ---- 4 --- Voltage at mass air sensor with hot wire circuit; open or short circuit

Base ---- 8 ---- 5 --- Maximum permissible temperature in module box exceeded
--------- 8 ---- 6 --- Electromagnetic a/c compressor clutch blocked
--------- 8 --- 12 --- Voltage supply for ABS control module, ABS/ASR control module or ASD control module interrupted

ABS ----- 6 --- 30 --- CAN data line to electronic accelerator/cruise control/ idle speed control module

EA/CC/ISC 7 ---- 3 --- Right EA/CC/ISC actuator (left cylinder bank) (M16/1)
--------- 7 ---- 5 --- Stop lamp switch (S9/1)
--------- 7 ---- 6 --- Starter lock-out/backup lamp switch
--------- 7 --- 14 --- Closed throttle position contact switch

Has the wiring harness been replaced . . ?? If so, it certainly looks like a going bad ETA or supporting 'switches".

Also the "LH" voltage is a strange code w/ an ETA failure. You may want to check it out . . .

What about a CEL?? Is it not lighted?? If so, check pin 19, there s/b some codes there.

Finally, read Menu#24 . . here

Check the smallest components first (brake switch, etc etc) as any single point of failure on these ASR lights will light up the codes like a christmas tree!

Ever solve this problem?

I'm getting the same thing (pin #7 3, 5,6, & 14), though no "limp mode"
drives normally except doesn't shift right under kick down WOT (wants to stay in that gear).

Can't clear ABS/ASR lights with simple 3 wire reader (at pin #7)
