AFIS422VSX-B-021318-OP
Post Installation System Operation Test
Perform the following tests before mounting the module, to allow easy viewing of the diagnostic LED’s, if
needed.
1. Place transmission in Park and start the engine. Vehicle may enter Fast Idle if VBAT is low. Either wait
to see if the battery charges and Fast Idle stops, or place a charger on the vehicle to disable the VBAT
low trigger to allow testing of other triggers.
2. Manually engage Fast Idle by having aftermarket vehicle equipment ground the Green wire. Engine speed
will increase to the set RPM level. If this does not occur, check harness connections. Also see diagnostics
below.
3. Assuming Fast Idle engaged, keep the Green wire grounded, and depress the Service Brake for 1 second.
Fast idle will temporarily disengage anytime the Service Brake is depressed, but will automatically reengage
after approximately 2 seconds once the Brake pedal is released.
4. Place transmission shift lever in the “Neutral” position. (Green wire still grounded). The system must not
activate Fast Idle.
The AFIS422VSX-B is properly installed only if it passes all of the above steps
.
Module Mounting
Ensure all harnesses are properly connected and routed and are not hanging below the dash area. Mount the
AFIS422VSX-B module using screws or double sided tape and reinstall all panels.

Fast Idle Status Codes
Status Codes provide the current status of
the Fast Idle system. The on-board
“Status” LED will flash a 2-digit code as
shown in the table. The first digit will
flash, wait half a second, flash the second
digit, then wait one second before the
next code. The Status Codes continue to
flash until the module is reset (cycle key),
or the test input is momentarily grounded
again.
Diagnostics
Diagnostic mode is entered by
momentarily shorting the two gold
“Test” pads together on the module.
The module provides diagnostic LEDs
which illuminate according to the
following table. To exit this mode,
cycle the key or momentarily ground
the “Test” pad again.
