Furthermore, the check can only be performed up to 4 times per trip. If the test is repeated, intervals of at least 30 seconds are required between checks.
While Secondary Air injection system operation using the GTS is prohibited, the GTS display indicates the prohibition (WAIT or ERROR).
If ERROR is displayed on the GTS during the test, stop the engine for 10 minutes, and then try again.
Performing Secondary Air Injection Check repeatedly may cause damage to the Secondary Air injection system. If necessary, leave an interval of several minutes between Secondary Air Injection Check operations to prevent the system from overheating.
When performing the Secondary Air Injection Check operation after the battery cable has been reconnected, wait for 7 minutes with the ignition switch turned to ON or the engine running.
