Diagnosis & fix steps
Inducement System - General Warning (SCR System Failure).
LOGIC: This is a "Strategic Code." The ECU has detected a fault in the SCR system and is legally required to warn the operator before cutting power.
Red Seal field insights
Pro-Tip: P1187 is the "Headline." It usually doesn't stay alone; it will always be accompanied by the "Root Cause" code (like P1122). Think of P1187 as the alarm clock and the other code as the reason the alarm is going off.
Same code keeps coming back?
That's a program problem, not a part problem. Book a 30-minute uptime review with Grant, a Red Seal Heavy Duty Technician.
