NOTE
Air system pressure must be 120 psi (827 kPa) before
beginning troubleshooting. If air pressure gage does
not indicate 120 psi (827 kPa), wait for system air
pressure to build before beginning troubleshooting.
CTI air lines are pressurized only when CTIS is in
inflate, deflate, or test cycles.
Normal inflation time from EMERGENCY to HIGHWAY
setting is approximately 5 minutes
Excess inflation times, sometimes accompanied by a
flashing LOW AIR light is normal if engine is at idle
RPM and/or air operated accessories are being used.

(2)
Disconnect CTI wire harness connector from
controller.
NOTE
Pay special attention to pin 2.
(3)
Place positive (+) probe of multimeter on pin 1 of
