SUBJECT:

Sedona (VQ) ABS/ESC Warning Lamp ON – Poor Grounds

 

Affected Vehicle Range:

2006 – 2007 Sedona (VQ) produced before March 8, 2006

 

Some 2006 – 2007 Sedona (VQ) vehicles with a production date earlier than March 8, 2006 may exhibit a customer concern of an ABS/ESC Warning Lamp (MIL) being illuminated. Various DTC’s such as C2402 or U0001 may also be stored in the control module – OR – the GDS Scan Tool may not be able to communicate with the ABS/ESC system at all. Do NOT replace an ABS/ESC unit without at least first applying the procedure described in this TSB. These symptoms may result from poor grounds at G19 and/or G20, caused by paint remains between the bolt and mating weld nut attaching the ground terminal to the body. This TSB provides a procedure to properly correct this condition. Remember too, that other poor connections may exist, and should also be checked prior to any part replacement.
