air suspension switches

[dave1764]

I have the optional performance or touring choice switches in my 98ssei and no matter witch i push both lights stay on. I click like it should but wondered if that is normal? I think i can feel the difference in the ride. thanks

Those are the CCR switches, Computer Command Ride. They control the damping of the struts. If both lights are on, there is an error and they are not working. The system continually retries on error, so of it is a momentary error, it will go away. If it stays on, most likely one of the struts has failed.

[dave1764]

every once in a while they will flash but 99% of the time they both stay lit. It rides level and never bottoms out on any side. any easy way to test?

[sonoma_zr2]

This has nothing to do with ride height, that is the elc system. CCR is strictly strut damping, how soft or hard the ride is. Yes, you can query the system to see which strut is erroring out.

[dave1764]

how do you do it?

[sonoma_zr2]

connect pins 3 and 4 of DLC connector to enter diagnostics (this is the connector above your feet under the dash)
turn ignition to "run" position
check and record codes

The blink codes seq starts with a short lamp off period. Then code 12 is displayed three times to mark the beginning of the seq. Next, each stored error code is blinked out in ascending order. Each error code is displayed three times before proceeding to the next code. After all error coded have been displayed, the entire seq will begin again by displaying the code 12 three times.

i have checked and there are no engine codes. I tested it at advance auto parts. Those machines should catch those codes should it not? I am new to the OBDII system use to OBDI

[sonoma_zr2]

code 12 - initialization
code 23 - left front actuator position error
code 24 - right front actuator position error
code 25 - left rear actuator position error
code 26 - right rear actuator position error
code 31 - lift/dive signal error
code 32 - lateral accelerator switch error
code 33 - driver select switch error
code 34 - vehicle speed signal error

no, you have to do it with the jumper test

[sonoma_zr2]

I forgot to mention, these codes are blinked out on the ccr selector switch lights

[dave1764]

oh ok sweet thanks i will do that in the morning. I will just use the jump method you told about

[trf_ssei]

is this an obd ll or obd l system? I also have a 98 ssei

[wjcollier07]

1996+ is OBD II

[dave1764]

ok so it took a long time but i finally got around to pulling the codes off the switches.
23
24
25
31
i read what they are above and know need to know what i need to do to fix
thanks

[trf_ssei]

how do u know what the code is? example of a sequence? say code 31.

[dave1764]

well first comes the 12 code showing that the system is functioning correctly. blink pause blink blink, then the 23,24,25
blink-blink-blink-pause-blink would be the 31 code,

[trf_ssei]

awesome i wanted to check mine to but wasn't sure how to inturpret the codes..

[dave1764]

yup thats all there is to it. oh and the same code will flash three times then move on to the next code. when all the codes have been displayed it will flash 12 again

From your symptoms, my best advice is to live without it. It's a substandard system at best even when it works, and the replacement struts are either impossible to find or horribly expensive (600-800 each).
