ABS LAMP ON C1165/C1175 AND/OR C1235/C1236

2007 Edge/MKX vehicles built before 6/1/2007 (FWD only) may exhibit an Anti-Lock Brake System (ABS) warning lamp and/or a Electronic Stability Control (ESC) warning lamp illuminated with diagnostic trouble codes (DTCs) C1165/C1175 and/or C1235/C1236.

This may be due to a faulty rear wheel speed sensor.

SERVICE PROCEDURE

Verify DTCs C1235/C1236 and/or C1165/C1175 are present. If so, continue on to Step 2. For all other codes follow normal Workshop Manual diagnostics.
With the ignition off, proceed with the replacement of the faulted wheel speed sensor.

NOTE: IT IS NOT NECESSARY TO REMOVE THE HARNESS ROUTING BRACKETS WHEN PERFORMING THE REPLACEMENT PROCEDURE.

With a new wheel speed sensor installed, torque the retaining bolt to 7 N-m (62 lb-in).
Clear continuous DTCs.

NOTE: THE ABS SYSTEM CONFIRMS REAR WHEEL SPEED SENSOR SIGNAL INPUT BASED ON SEVERAL WHEEL REVOLUTIONS ABOVE 24 KM/H (15 MPH). DRIVE VEHICLE FOR AT LEAST 75 FEET AT OR ABOVE 15 MPH. IF WHEEL SPEED SIGNAL INPUT IS MISSING THE ABS LIGHT WILL ILLUMINATE.
