Type of diagnosis:
Continuous

Enable criteria:
Engine running.
NONE of the following DTCs must be detected: P0122, P0123, P0222, P0223

Secondary air switched off.

OK report:
Fault criterion not fulfilled and vehicle speed over 0 km/h for more than 60 s.

Fault handling:
Type III
(See Description of On-Board Diagnostics/Fault handling III, "Other emission-related components and functions" for more information.)

Checking the wiring harness
Move the wiring harness at several spots and in several directions to reveal intermittent breaks and short-circuits. Check switches, connectors and crimp connections for oxidation, retracted pins and pin clamping force.
