CADILLAC DEVILLE TERMINAL PROBLEM

1997 Cadillac Deville • 208,019 miles

I, m replying about the brake warning light staying on it is the red light, I got a code c1241abs brake problem would the abs problem have anything to do with the red warning light, what cause code c1241 show up what can I do to fix that problem too.

DTC C1241: MAGNASTEER CIRCUIT MALFUNCTION

1. Perform diagnostic system check. See DIAGNOSTIC SYSTEM CHECK . After performing diagnostic system check, go to next step.
2. Check Magnasteer actuator connector and EBCM/EBTCM connector and wiring for damage. If connector or wiring is damaged, go to next step. If connector or wiring is okay, go to step 4).
3. Repair as necessary. After repairs, perform DIAGNOSTIC SYSTEM CHECK .
4. Disconnect Magnasteer actuator connector. Using DVOM, measure resistance between terminals of Magnasteer actuator. Actuator is located on power steering rack. See WIRING DIAGRAM . If resistance is
1.6 3.1 ohms, go to next step. If resistance is not 1.6 3.1 ohms, go to step 6).
5. Using DVOM, measure resistance between terminal "A" (Gray wire) of Magnasteer actuator and ground. Also, using DVOM, measure resistance between terminal "B" (White wire) of Magnasteer actuator and
ground. See WIRING DIAGRAM . If resistance is infinite for both measurements, go to next step. If resistance is not infinite for both measurements, go to step 7).
6. Replace Magnasteer actuator. After repairs, perform DIAGNOSTIC SYSTEM CHECK .
7. Turn ignition off. Disconnect EBCM/EBTCM connector. Connect Pinout Box (J 39700) and Bosch Adapter Cable (J 39700 25) to harness connector. Using DVOM, measure resistance between pinout box
terminals "C" and "B". If resistance is infinite, go to next step. If resistance is not infinite, go to step 9).
8. Repair short to ground in Gray wire between actuator and EBCM/EBTCM. After repairs, perform DIAGNOSTIC SYSTEM CHECK .
9. Using DVOM, measure resistance between pinout box terminals "F" and "B". If resistance is infinite, go to next step. If resistance is not infinite, go to step 11).
10. Repair short to ground in White wire between actuator and EBCM/EBTCM. After repairs, perform DIAGNOSTIC SYSTEM CHECK .
11. Reconnect Magnasteer actuator connector. Using DVOM, measure resistance between pinout box terminals "C" and "F". If resistance is 1.6 3.1 ohms, go to step 17). If resistance is not 1.6 3.1 ohms, go to next
step.
12. If resistance is less than 1.6 3.1 ohms, go to next step. If resistance is greater than 1.6 3.1 ohms, go to step 14).
13. Repair short between White wire and Gray wire. After repairs, perform DIAGNOSTIC SYSTEM CHECK .
14. Connect a fused jumper between pinout box terminals "C" and "B". Disconnect Magnasteer actuator connector. Using DVOM, measure resistance between terminal "A" (Gray wire) of Magnasteer actuator
connector and ground. See WIRING DIAGRAM . If resistance is 0 5 ohms, go to next step. If resistance is not 0 5 ohms, go tostep 16).
15. Repair open in White wire between actuator and EBCM/EBTCM. After repairs, perform DIAGNOSTIC SYSTEM CHECK .
16. Repair open in Gray wire between actuator and EBCM/EBTCM. After repairs, perform DIAGNOSTIC SYSTEM CHECK .
17. Turn ignition on, with engine off. Using DVOM, measure voltage at pinout box terminal "C". If voltage is greater than one volt, go to next step. If voltage is less than one volt, go to step 19).
18. Repair short to voltage in Gray wire between actuator and EBCM/EBTCM. After repairs, perform DIAGNOSTIC SYSTEM CHECK .
19. Turn ignition on, with engine off. Using DVOM, measure voltage at pinout box terminal "F". If voltage is greater than one volt, go to next step. If voltage is less than one volt, go to step 21).
20. Repair short to voltage in White wire between actuator and EBCM/EBTCM. After repairs, perform DIAGNOSTIC SYSTEM CHECK .
21. Replace EBCM/EBTCM. After repairs, perform DIAGNOSTIC SYSTEM CHECK .
