X46 - Check Power-to-(Low Speed) Fan Circuit Continuity
- Key Off.
- CCRM disconnected.
- Disconnected cooling fan.
- Measure resistance between the Power-to-(Low Speed) Fan circuit pin at the cooling fan vehicle harness connector and Pins 1 and 2 at the CCRM vehicle harness connector.
- Are both resistances less than 5.0 ohms?
YES -- GO to X47. X47 - Check CCRM
NO -- SERVICE open in Power-to-(Low Speed) Fan circuit between the CCRM and the FANM splice into the circuit. RECONNECT all components. Rerun quick test. Diagnostic Subroutines (DSR) - Extracting Codes
