2.
Verify the stop lamps operate correctly by pressing and releasing the brake pedal with the ignition switch in the OFF position. If the stoplamps do not operate correctly, refer to
Section 417-01
. If the stoplamps operate correctly, proceed to the next step.
3.
Verify the base brake system operates correctly. If any concerns are present, address them before continuing with any ABS concerns. Refer to
Section 206-00
. If the base brake
system operates correctly, proceed to the next step.
4.
Visually inspect for obvious signs of mechanical or electrical damage.
Visual Inspection Chart
5.
If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
6.
NOTE: Make sure to use the latest scan tool software release.
If the cause is not visually evident, connect the scan tool to the data link connector (DLC).
7.
NOTE: The vehicle communication module (VCM) LED prove out confirms power and ground from the DLC are provided to the VCM.
If the scan tool does not communicate with the VCM:
check the VCM connection to the vehicle.
check the scan tool connection to the VCM.
refer to
Section 418-00
, No Power To The Scan Tool, to diagnose no communication with the scan tool.
8.
If the scan tool does not communicate with the vehicle:
verify the ignition key is in the ON position.
verify the scan tool operation with a known good vehicle.
refer to
Section 418-00
to diagnose no response from the PCM.
9.
Carry out the network test.
If the scan tool responds with no communication for one or more modules, refer to
Section 418-00
.
If the network test passes, retrieve and record continuous memory DTCs.
10.
Clear the continuous DTCs and carry out the self-test diagnostics for the ABS module and the instrument cluster.
11.
If the DTCs retrieved are related to the concern, go to the ABS Module DTC Chart or the Instrument Cluster DTC Chart. For all other DTCs, refer to
Section 419-10
.
12.
If no DTCs related to the concern are retrieved, GO to
