36A No Response Messages For AC/AY Body Systems

There are three ways to get to this test:

1. The DRBII is currently connected to the CCD bus diagnostic connector and you have selected ENGINE from the main menu*.

2. A bus failure message flow chart brought you here.

3. The DRBII showed a "N0 RESPONSE" message when an attempt was made to read information from a module*.

If item 1 is the reason you are here, you must either select an appropriate selection from the menu (BODY, SUSPENSION, ABS, TRANSMISSION, or THEFT ALARM) or, if you want to perform engine tests, connect the DRBII to the SCI connector in the engine compartment.

If item 2 is the reason you are here, you must verify that you can access all the modules that are on the vehicle. Perform the tests below as necessary.

If item 3 is the reason you are here, you should check the Electronic Instrument Cluster first. Through our research we have determined that an open bus (+) wire at the EIC can cause the EVIC head to flash "IMPROPER VOLTAGE" and "AIR SUSPENSION" messages inappropriately. It can cause all the segments on the EIO to be missing, the bus failure message "SHORT TO GROUND" or "NOT READING BUS MESSAGES CORRECTLY" to flash once when checking the bus, and most importantly, it will cause the DRBII to show a "NO RESPONSE" under each module. The DRBII will also show a "NO RESPONSE" message when you are trying to access a module that is not on the vehicle.

* It is possible to monitor the Engine Controller for an "ACTIVE ON THE BUS" message only at the CCD bus diagnostics connector. Monitor the engine controller for a "NO RESPONSE" message by selecting SYSTEM TEST under any of the module test selection menus.
