22102 SENSOR INPUT VOLTAGE HIGH INP1
This alarm is an indication that there is a short in the DC current transformer wiring from another
(nominal 12 VDC) circuit into the transducer or CT sensor circuit.
• ACTIVATION: Voltage from main microprocessor to the sensors is greater than 5.5 VDC.
• UNIT CONTROL: Alarm only.
• RESET CONDITION: Auto reset when sensor voltage is correct, alarm reset or alarm may be manually
reset 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, clear the
alarm(s). (See Note 1 in Notes Section.) 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 Wiring
If a transducer reading is not within a reasonable range of gauge reading, check wires to sensors for
short.
• For CSP, check wiring from 2MM-20, 2MM-30 and 2MM-9.
• For EVOP, check wiring from 2MM-25, SP-20 and 2MM-17.
• For CDP, check wiring from 2MM-21, SP-20 and 2MM-10.
• For ECOP, check wiring from 2MM-28, SP-20 and 2MM-14.
2. Check CT Wiring - Check wires to sensor for short from another circuit. Check wiring from 2MM-29, 2MM-
12 and 2MM-23 to PCM.
3. Replace Main Microprocessor - Download data and replace main microprocessor. For complete Main
Microprocessor Module replacement instructions refer to Section 5.5.2.
22103 INPUT LOST CONFIGURATION
• ACTIVATION: Input Board reports an invalid configuration.
• UNIT CONTROL: Required Shutdown.
• RESET CONDITION: Auto reset when communication is restored, or alarm may be manually reset 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, clear the
alarm(s). (See Note 1 in Notes Section.) 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 Wiring - Check logic power connections. Check wiring at 1MM-6 & 1MM-1.
2. Replace Main Microprocessor - Download data and replace main microprocessor. For complete Main
Microprocessor Module replacement instructions refer to Section 5.5.2.
