DIAGNOSIS SYSTEM
The Electronically Controlled Transmission system has built-in self-diagnostic functions. If the malfunction occurs in the system, the Engine Control Module (ECM) stores the diagnostic trouble code in memory and the O/D OFF (Overdrive OFF) indicator light blinks to inform the driver. The diagnostic trouble code stored in memory can be read out by the following procedure.
O/D OFF INDICATOR LIGHT INSPECTION
1. Turn the ignition switch to ON.
2. Check if the O/D OFF indicator light lights up when the O/D main switch is pushed out to OFF and goes off when the O/D main switch is pushed in to ON.
HINT:
- If the O/D OFF indicator light does not light up or stays on all the time, carry out the check for 0/ D OFF Indicator Light Circuit.
- If the O/D OFF indicator light blinks, a trouble code is stored in the ECM memory.
HOW TO DISPLAY AND READ DIAGNOSTIC TROUBLE CODES
1. Hook up the LEXUS hand-held tester to the DLC2.
2. Read the diagnostic trouble codes by following the prompts on the tester screen.
Please refer to the LEXUS hand - held tester operator's manual for further details.
