CHECK MODE PROCEDURE
HINT:
Intelligent tester only:
Compared to normal mode, check mode is more sensitive to
malfunctions. Therefore, check mode can detect the
malfunctions that cannot be detected by normal mode.
NOTICE:
All the stored DTCs and freeze frame data are erased if:
1) the ECM is changed from normal mode to check mode
or vice versa; or 2) the ignition switch is turned off or
turned to the ACC position from the ON position while in
check mode.
Before changing modes, always check and make a note
of any DTCs and freeze frame data.
1. CHECK MODE PROCEDURE (Using an intelligent
tester)
(a) Check and ensure the following conditions:
(1) Battery voltage 12 V or more
(2) Throttle valve fully closed
(3) The shift lever in the P or N position
(4) A/C switched OFF
(b) Turn the ignition switch off.
(c) Connect an intelligent tester to the DLC3.
(d) Turn the ignition switch to the ON position.
(e) Turn the tester ON.
(f) Select the following menu items: DIAGNOSIS /
ENHANCED OBD II / CHECK MODE.
(g) Switch the ECM from normal mode to check mode.
(h) Make sure that the MIL flashes as shown in the
illustration.
(i) Start the engine.
(j) Make sure that the MIL goes off.
(k) Simulate the conditions of the malfunction described
by the customer.
(l) Check for DTCs and freeze frame data using the
tester.
