Checking The Component And Wiring
Check the cable between phone module (PHM) connector B and the connector for the SIM card reader. Check for an open-circuit.
Check between:
- control module connector terminal B#1 (#21) and SIM card reader connector terminal #1
- control module connector terminal B#2 (#22) and SIM card reader connector terminal #2
- control module connector terminal B#3 (#3) and SIM card reader connector terminal #3
- control module connector terminal B#4 (#4) and SIM card reader connector terminal #4
- control module connector terminal B#5 (#5) and SIM card reader connector terminal #5
- control module connector terminal B#6 (#6) and SIM card reader connector terminal #6.
Check the connectors for loose connections, damaged or bent terminal pins and oxidation.
Try replacing the SIM card reader if no fault is found in the cable.
Remedy as necessary.
