Series 50G/60G Troubleshooting – Section 5.31 PID 111, FMI 4, Flash Code 13, Coolant Level Sensor Input Voltage Low

Section 5.31
PID 111, FMI 4, Flash Code 13, Coolant Level Sensor Input Voltage Low

The voltage input for the Coolant Level Sensor (CLS) is low due to a short to ground.‪

Section 5.31.1
TROUBLESHOOTING PID 111, FMI 4, FLASH CODE 13

Troubleshoot as follows:‪

1. Check wire 115 (orange, coolant level) cavity H-3 in the Vehicle Interface Harness (VIH) 30–pin connector for a short to ground (see Figure "Vehicle Interface Harness 30–pin Connector" ). If there is a short, replace or repair the wire(s).

   1. If the code is still active, go to step .
   2. If the code is no longer active, refer to "5.31.2 Verification" .
2. Check cavity A in the CLS connector for a short. If there is a short, replace or repair the wire(s).
   1. If the code is still active, call Detroit Diesel Technical Service.
   2. If the code is no longer active, refer to "5.31.2 Verification" .

Section 5.31.2
Verification

Verify troubleshooting as follows: ‪

1. Check the DDR to see if PID 111, FMI 4, Flash Code 13 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.
