DTC C0196: Yaw Rate Circuit Malfunction (Intrigue): Diagnosis

WARNING: This page is about a different car, the 2001 Pontiac Grand Prix, 2001 Pontiac Firebird, 2001 Oldsmobile Intrigue, and 2001 Chevrolet Camaro. However, it is still accessible from the selected car via links, so may be relevant.
  1. Perform DIAGNOSTIC SYSTEM CHECK  under DIAGNOSIS & TESTING. Go to next step.
  2. Turn ignition off. Disconnect EBCM. Install Universal Pinout Box (J 39700) with Cable Adapter (J 39700-530) between EBCM and EBCM connector. Turn ignition on, engine off. Using DVOM, measure voltage between universal pinout box terminals No. 26 (Dark Blue wire) and No. 15 (Black/White wire). If voltage is 0.23-4.78 volts, see DIAGNOSTIC AIDS  . If voltage is not 0.23-4.78 volts, go to next step.
  3. Turn ignition off. Disconnect yaw/lateral accelerometer sensor. Turn ignition on, engine off. Using DVOM, measure voltage between ignition (Pink wire) and ground (Gray/Black wire) circuits of yaw/lateral accelerometer sensor. If battery voltage is present, go to step  5 . If battery voltage is not present, go to next step.
  4. Check Pink wire between yaw/lateral accelerometer sensor and underhood accessory wiring junction block for high resistance or open. If problem was found, repair as necessary. After repairs, go to step  19 . If problem was not found, see POWER DISTRIBUTION article in WIRING DIAGRAMS.
  5. Reconnect yaw/lateral accelerometer sensor. Using DVOM, measure voltage between universal pinout box terminals No. 26 (Dark Blue wire) and No. 15 (Black/White wire). If voltage is less than 4.78 volts, go to next step. If voltage is not less than 4.78 volts, go to step  13 .
  6. Using DVOM, measure voltage between universal pinout box terminals No. 26 (Dark Blue wire) and No. 15 (Black/White wire). If voltage is greater than 0.23 volt, go to next step. If voltage is not greater than 0.23 volt, go to step  12 .
  7. Using DVOM, measure voltage between universal pinout box terminals No. 16 (Orange wire) and No. 15 (Black/White wire). If voltage is less than 2 volts, go to step  11 . If voltage is not less than 2 volts, go to next step.
  8. Using DVOM, measure voltage between universal pinout box terminals No. 16 (Orange wire) and No. 15 (Black/White wire). If voltage is greater than 3 volts, go to step  10 . If voltage is not greater than 3 volts, go to next step.
  9. Turn ignition off. Disconnect negative battery cable. Measure resistance between Gray/Black wire of yaw/lateral accelerometer connector and ground. If resistance is 0-5 ohms, go to step  16 . If resistance is not 0-5 ohms, go to step  14 .
  10. Check Orange wire (5-volt reference circuit) of yaw/lateral accelerometer sensor for short to voltage. If problem was found, repair as necessary. After repairs, go to step  19 . If problem was not found, go to step  15 .
  11. Check Orange wire (5-volt reference circuit) of yaw/lateral accelerometer sensor for short to ground, high resistance or open. If problem was found, repair as necessary. After repairs, go to step  19 . If problem was not found, go to next step.
  12. Check Dark Blue wire (yaw rate signal circuit) of yaw/lateral accelerometer sensor for short to ground, high resistance or open. If problem was found, repair as necessary. After repairs, go to step  19 . If problem was not found, go to step  15 .
  13. Check Dark Blue wire (yaw rate signal circuit) of yaw/lateral accelerometer sensor for short to voltage. If problem was found, repair as necessary. After repairs, go to step  19 . If problem was not found, go to step  15 .
  14. Disconnect EBCM. Check Gray/Black wire (ground circuit) of yaw/lateral accelerometer sensor for high resistance or open. If problem was found, repair as necessary. After repairs, go to step  19 . If problem was not found, go to next step.
  15. Check yaw/lateral accelerometer sensor connector for poor connections. If problem was found, repair as necessary. After repairs, go to step  19 . If problem was not found, go to step  17 .
  16. Check EBCM connector for poor connections. If problem was found, repair as necessary. After repairs, go to step  19 . If problem was not found, go to step  18 .
  17. Replace yaw/lateral accelerometer sensor. See YAW/LATERAL ACCELEROMETER SENSOR (INTRIGUE)  under REMOVAL & INSTALLATION. After repairs, go to step  19 .
  18. Replace EBCM. See ELECTRONIC BRAKE CONTROL MODULE  under REMOVAL & INSTALLATION. After repairs, go to next step.
  19. Using scan tool, clear DTCs. Operate vehicle. If DTC does not reset, system is okay.
