Series 50G/60G Troubleshooting – Section 5.30 PID 111, FMI 3, Flash Code 16, Coolant Level Sensor Input Voltage High

Section 5.30
PID 111, FMI 3, Flash Code 16, Coolant Level Sensor Input Voltage High

The voltage input to the Coolant Level Sensor (CLS) is high due to an open wire or a short.‪

Section 5.30.1
Troubleshooting PID 111, FMI 3, FLASH CODE 16

Troubleshoot as follows:‪

1. Check wire 115 (orange, coolant level) cavity H-3 in the Vehicle Interface Harness (VIH) 30–pin connector to see if it is open (see Figure "Vehicle Interface Harness 30–pin Connector" ). Also check cavity A in the CLS connector. Repair or replace and open wire(s).

   1. If the code still active, go to step .
   2. If the code is no longer active, refer to "5.30.2 Verification" .
2. Check wire 115 (orange, coolant level) cavity H-3 in the VIH 30–pin connector for a short to Sensor Supply Voltage (5VDC) (see Figure "Vehicle Interface Harness 30–pin Connector" ). Also check cavity A in the CLS. If there is a short, replace or repair wire(s).
   1. If the code is still active, call Detroit Diesel Technical Service.
   2. If the code is no longer active, refer to "5.30.2 Verification" .

Section 5.30.2
Verification

Verify troubleshooting as follows: ‪

1. Check the DDR to see if PID 111, FMI 3, Flash Code 16 is still active.
   1. If the code is still active, go to step 2.
   2. If the code is not active, troubleshooting is complete.
2. If the code is still active, call Detroit Diesel Technical Service.
