Toyota CH-R Service Manual: Test Mode Procedure

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.
  • During test mode (signal check mode), the system is not initialized even if the initialization procedure is performed.

(a) Turn the ignition switch off.

(b) Connect the Techstream to the DLC3.

(c) Turn the ignition switch to ON and the Techstream on.

(d) Enter the following menus: Chassis / Tire Pressure Monitor / Utility / Signal Check.
