| Title: TIRE PRESSURE MONITORING: TIRE PRESSURE WARNING SYSTEM: TEST MODE PROCEDURE; 2018 MY Camry [03/2017 - 06/2017] | ||
TEST MODE PROCEDURE
TEST MODE (SIGNAL CHECK MODE) PROCEDURE
HINT:
-
When entering test mode (signal check mode), the tire pressure warning ECU and receiver sets all the test mode (signal check mode) DTCs first.
After the tire pressure warning ECU and receiver completes the signal check for each inspection item, the DTCs for systems that are determined to be normal will be cleared.
The DTCs for other inspection items may not be cleared when only a certain signal is inspected.
- When test mode (signal check mode) returns to normal mode, all the test mode (signal check mode) DTCs will be cleared.
- Operation of the tire pressure warning reset switch can be checked in test mode (signal check mode).
- During test mode (signal check mode), the system will not be initialized by operating the steering pad switch assembly. The circuit of the tire pressure warning reset switch can be inspected during this mode.
(a) Turn the ignition switch off.
(b) Connect the Techstream to the DLC3.
(c) Turn the ignition switch to ON.
(d) Turn the Techstream on.
