J7 CHECK THE ABS (ANTI-LOCK BRAKE SYSTEM) MODULE LATERAL ACCELERATION (LAT_ACCL) PID (PARAMETER IDENTIFICATION)
NOTE: The vehicle must be on level ground and at a complete standstill. Any vehicle movement results in false values for this test.
Using a diagnostic scan tool, monitor the ABS module LAT_ACCL PID.
Is the LAT_ACCL PID value between -0.4 and 0.4?
Yes | GO to J8 |
|---|---|
No | GO to J9 |
J8 CHECK THE ABS (ANTI-LOCK BRAKE SYSTEM) MODULE LONGITUDINAL ACCELERATION (LONG_ACCL) PID (PARAMETER IDENTIFICATION)
NOTE: The vehicle must be on level ground and at a complete standstill. Any vehicle movement results in false values for this test.
Using a diagnostic scan tool, monitor the ABS module LONG_ACCL PID.
Is the LONG_ACCL PID value between -0.4 and 0.4?
Yes | GO to J10 |
|---|---|
No | GO to J9 |
J9 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 J10 |
|---|---|
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). |
J10 VERIFY ALL WIRING CONNECTIONS
NOTICE: The ignition must be set to OFF when disconnecting PSCM electrical connectors. Failure to follow this direction may lead to Diagnostic Trouble Codes (DTCs) being set in the PSCM which can not be cleared and result in the need to install a new EPAS gear.
Ignition OFF. Disconnect PSCM C1463A and C1463B (if not previously disconnected). Using a good light source, inspect ABS module C135 for the following:
corrosion - install a new connector or terminal and clean module pins
