INSPECTION PROCEDURE
PROCEDURE
-
CHECK DTC OUTPUT (ALL)
-
Connect the intelligent tester to the DLC3.
-
Turn the power switch on (IG).
-
Check for DTCs of all systems by following the prompts on the intelligent tester screen.
-
Check if DTCs are output.
Result Result Proceed to Hybrid vehicle control ECU outputs P2532-772 (logical contradiction, No. 2 IG signal) A Hybrid vehicle control ECU does not output P2532-772 (logical contradiction, No. 2 IG signal) B
(for LHD)
C
(for RHD)
