CHECK REMOTE ALARM LIGHT
• ACTIVATION: The fault output circuit (amber “check unit” LED’s) to the light bar is shorted.
• UNIT CONTROL: Engine and Electric Operation: Alarm only.
• RESET CONDITION: Auto Reset when Alarm light current (amp) draw is normal, or alarm may be manu-
ally reset via keypad or by turning the unit off, then back on again.
NOTE: Follow the steps below until a problem is found. Once a repair or correction has been made, the active
alarm should clear itself (see reset condition above). Operate the unit through the appropriate modes to see if
any active alarm occurs. Continue with the steps below as necessary.
CORRECTIVE ACTIONS:
1.
Check Light Bar Wiring
a. Inspect light bar & connector. Verify there is no damage to light bar, and no damage, moisture, or
corrosion in connector.
b. Place the SROS in the OFF position and check:
• fuses F5 & F11 in the PCM, continuity of the wiring from PCM-7 to LB-B, continuity of the wiring from
LB-G -including SP10 to ground, continuity of the wiring from LB-H to 3MM-7. Verify correct fuse,
see
. Check connectors and wiring between terminals for damage, moisture or corrosion.
2.
Check Light Bar
Check operation of 2-Light Bar Refer to
for information on testing the light bar.

CHK AFA SOLENOID CIRCUIT
• ACTIVATION: A problem has been detected in the AutoFresh Air Exchange relay coil circuit. If this alarm
is activated while the control system is calling for AFAR to be energized, the circuit is detected shorted. If
this alarm occurs at any other time, the circuit is detected open.
• UNIT CONTROL: Engine and Electric Operation: Alarm only. \
• RESET CONDITION: Auto reset when circuit is normal, or alarm may be manually reset using the display
mounted keys or by turning the unit off, then back on again.
NOTE: Follow the steps below until a problem is found. Once a repair or correction has been made, the active
alarm should clear itself (refer to reset condition above). Operate the unit through the appropriate modes to see
if any active alarm occurs. Continue with the steps below as necessary.
CORRECTIVE ACTIONS:
1.
Check Relay
a. Inspect relay socket and connection pins inside PCM. Verify there is no damage to relay, and no
damaged or corroded connections.
b. Check resistance of coil (terminals 1 & 2). Refer to
2.
Check Power And Wiring
a. Check for power at fuse F10 terminal A inside PCM. Must have minimum 11 VDC. If not, check
PCM circuit and fuse F5.
b. Check fuses F5 & F10. Verify correct fuse, see
c. Check for power at AFAR + terminal. Replace PCM.
d. Set the AutoFresh Air Functional Parameter to OPEN and ensure the set point is above 30°F
(
−
1.0°C). The AutoFresh air relay coil will be grounded by the main microprocessor at 3MM-13.
Check ground from 3MM-13 through PCM-26 to the AFAR - connection. Reset AutoFresh Air
Functional Parameter and setpoint as required following testing. If ground not good, check con-
nectors and wiring between terminals for damage, moisture or corrosion.
