Secondary Air Injection System (EMISSION CONTROL - V8) (page 7 of 8)

EMISSION CONTROL - V8

17-2-32 DESCRIPTION AND OPERATION

NOTE: Refer to 'SAI System Fault Finding' and 'Checking Malfunctions on SAI System' at the end of the 'Secondary 
Air Injection System Operation' section to determine root cause of fault codes.

The system diagnostics monitor the whole SAI system for correct operation. Malfunction of any one of the SAI 
components can cause the above fault codes to be stored.

Therefore, correct fault finding methods and investigation are essential to determine the root cause of the fault 
code(s). TestBook/T4 must be used to perform active SAI diagnostics.
