C1242–G SENSOR INPUT SIGNAL PERFORMANCE

For a complete wiring diagram Refer to Section 8W.

• When Monitored:

  Continuously, with ignition on, until vehicle speed exceeds 20 km/h (12.4 m.p.h.) for the first time, but not if the sensor voltage is out of range,

  Or, during diagnostic mode.

  Or, if the monitoring was inhibited by a corresponding diagnostics command.

  Or, if the vehicle speed has exceeded 20 km/h (12.4 m.p.h.) during the actual ignition cycle.

  Or, if at least one over spinning wheel is detected.

  Or, if one of the control functions is active.

• Set Condition:

  If the measured acceleration signal is higher than 0.8 g and longer than the specified detection time.

Diagnostic Test

WARNING: To avoid personal injury or death, check brake capability is available before road testing.

• Go To 2

• Perform the ABS Intermittent Condition diagnostic procedure in this Section.
• Refer to the ABS-INTERMITTENT CONDITION TEST. (Refer to 5 - BRAKES - DIAGNOSIS AND TESTING)

NOTE: Dynamics Sensor installation and mounting bolt torque is crucial for proper operation.

• Repair as necessary.
• Perform ABS VERIFICATION TEST. (Refer to 5 - BRAKES - STANDARD PROCEDURE).

• NOTE: Vehicles without a Dynamics Sensor replace Anti-Lock Brake Module.

  Replace the Dynamics Sensor or Anti-Lock Brake Module in accordance with the Service Information.
• Perform ABS VERIFICATION TEST. (Refer to 5 - BRAKES - STANDARD PROCEDURE).
