Test Description

The numbers below refer to the step numbers in the diagnostic procedure.

• 12
  
  This test isolates whether the short is to another TAC system circuit in the harness or within the TAC module.
• 26
  
  When the TAC module detects a condition within the TAC system, more than 1 TAC system related DTC may set. This is due to the many redundant tests run continuously on this system. Locating and repairing 1 individual condition may correct more than 1 DTC. Disconnecting components during testing may set additional DTCs. Remember this if you review the stored information in Capture Info.
