How to fix diagnose code C1234 Drive test: sensor cluster installation?

Step 1. Check for a DTC C1234 Drive test: sensor cluster installation

This DTC must be active for the results of this test to be valid.

Turn the ignition on, with the scan tool, read and record DTCs. With the scan tool, read and record environmental data to help identify the conditions in which the DTC was et. Perform the ECU initialization with drive test (see ABS verification test). Start the engine and apply the brake firmly, with the scan tool read and record DTCs.

Does the scan tool display C1234 Drive test: sensor cluster installation?

YES, go to step 2.

NO, perform the ABS intermittent.

Step 2. Check the Dynamics sensor installation

Dynamics sensor installation and mounting bolt torque is crusial for proper operation
Turn the ignition off, check the dynamics sensor for damaged, modified, and mounting brackets. Check the dynamics sensor mounting bolts for a loose or over tightened condition.

Were any problems found?

YES, repair as necessary.

NO, replace the Dynamics sensor. Perform the ABS Verification test.
