Diagnostic Trouble Code Chart

HINT:

Parameters listed in the chart may not be exactly the same as your readings due to the type of instrument or other factors.
If a trouble code is displayed during the DTC check, inspect the trouble areas listed for that code.
*: MIL flashes when a catalyst damaged misfire is detected.
*1: The MIL does not illuminate when a malfunction is detected in the CPU peripheral circuit of the ECM. It illuminate when a malfunction is detected in the ECM internal circuit: accelerator pedal position, brake switch, cruise control, heated oxygen sensor and throttle position.
*2: The MIL does not illuminate when a malfunction is detected in the cruise control cancel switch circuit of the ECM. It illuminate when a malfunction is detected in the main CPU and sub CPU of the ECM.
