The Engine Control Module (ECM) detects the following conditions:
•The signal voltage from the fuel temperature sensor is greater than 4.95 VDC for more than eight seconds.
Probable Causes:
1) ECM Connection/Harness
2) If code 232-3 or 232-4 (5 Volt Supply voltage codes) are active, troubleshoot those instead
3) Temperature sensor failure
4) Temperature sensor harness
5) ECM Failure
CAT 3406E (Prefix 5DS or 1LW) Fault Code: 12 PID: 111 SPN: FMI: 2 Coolant Level signal invalid
CAT 3406E (Prefix 5DS or 1LW) Fault Code: 02 PID: 244 SPN: FMI: 2 Event Recorder Data Lost
CAT 3406E (Prefix 5DS or 1LW) Fault Code: 01 PID: 71 SPN: FMI: 0 Idle Shutdown Override
CAT 3406E (Prefix 5DS or 1LW) Fault Code: 00 PID: 171 SPN: FMI: 11 Ambient Air Temperature Data Lost
CAT 3406E (Prefix 5DS or 1LW) Fault Code: 00 PID: 171 SPN: FMI: 4 Ambient Air Temperature voltage low
CAT 3406E (Prefix 5DS or 1LW) Fault Code: 00 PID: 171 SPN: FMI: 3 Ambient Air Temperature voltage high
