Test Mode Procedure

1. When the engine switch is turned on (IG), check that the absorber control indicator light will come on for approximately 2 seconds. (Absorber control switch is in the "NORMAL" position.)

   HINT:

   If the absorber control ECU stores any DTCs, the absorber control indicator light will come on.

   If the absorber control indicator light remains on or does not come on, proceed to troubleshooting for the indicator light circuit below.

HINT:

• If the engine switch is turned from on (IG) to on (ACC) or off during Test Mode (SIGNAL CHECK), all Test Mode DTCs will be erased.
• During Test Mode (SIGNAL CHECK), the absorber control ECU records all Test Mode DTCs. By performing the Test Mode (SIGNAL CHECK), the codes will be erased if normality is confirmed. The remaining codes will be the codes where an abnormality was found.

HINT:

The "SPORT" indicator (absorber control indicator light) comes on for 1 second when inputting each diagnostic signal.

1. Keep the absorber control switch in the "NORMAL" position.
2. Keep the vehicle stationary on a level surface for 1 second or more (Acceleration sensor check).
3. Turn the absorber control switch from the "NORMAL" to "SPORT" position and return to the "NORMAL" position. (An absorber control switch signal will be input.)

INPUT SIGNAL TABLE 

1. Read the DTC(s) by following the tester screen.

   HINT:

   See the list of Test Mode DTCs.

Result 

1. Clear the DTCs (See DTC CHECK / CLEAR ).
2. Check that absorber control indicator light blinks (Test Mode).
3. Turn both the engine switch off and intelligent tester switch off.
