G7 CHECK THE ABS (ANTI-LOCK BRAKE SYSTEM) MODULE PID (PARAMETER IDENTIFICATION) VALUES
NOTE: The vehicle must be on level ground and at a complete standstill during this step. Any vehicle movement results in false values for this test.
Ignition OFF. Ignition ON. Using a diagnostic scan tool, monitor the following ABS module Parameter Identifications (PIDs):
Yaw rate (YAW_RATE) Lateral accelerometer (LAT_ACCL) Longitudinal accelerometer (LONG_ACCL) Roll rate (ROLL_RATE)
Is the YAW_RATE PID value between -0.05 and 0.05, the LAT_ACCL PID value between -0.4 and 0.4, the LONG_ACCL PID value between -0.4 and 0.4, and the ROLL_RATE PID value between -0.05 and
0.05?
Yes | GO to G9 |
|---|---|
No | GO to G8 |
G8 CHECK THE RCM (RESTRAINTS CONTROL MODULE) INSTALLATION AND MOUNTING SURFACE
WARNING: Turn the ignition OFF and wait one minute to deplete the backup power supply. Failure to follow this instruction may result in serious personal injury or death in the event of an accidental deployment.
Ignition OFF. Wait one minute then disconnect RCM C310A and C310B. Inspect the RCM installation and make sure the fasteners are fully seated and tightened to specifications. REFER to: Restraints Control Module (RCM) (501-20B Supplemental Restraint System, Removal and Installation). Inspect the RCM mounting surface for damage, corrosion or dirt.
Is the RCM installed correctly and is the mounting surface clean and free from damage?
Yes | GO to G9 |
|---|---|
No | CLEAN or REPAIR the mounting surface or correctly REINSTALL the RCM as necessary. REFER to: Restraints Control Module (RCM) (501-20B Supplemental Restraint System, Removal and Installation). |
G9 CHECK FOR CORRECT RCM (RESTRAINTS CONTROL MODULE) OPERATION
Ignition OFF. Disconnect ABS module C135 and related in-line electrical connectors. Inspect the ABS module, RCM and related in-line electrical connectors for:
corrosion loose or spread terminals loose or frayed wire connections at terminals pushed-out or bent pins damage, pinched, cut or pierced wires
Repair any electrical connector concerns found, Refer to Wiring Diagrams Cell 5 for schematic and connector information. Ignition OFF. Wait one minute then connect RCM C310A and C310B. Make sure the connectors seat and latch correctly. Connect ABS module C135 and related in-line electrical connectors. Make sure the connectors seat and
