Toyota Camry and Cressida have two separate diagnostic connectors and two separate diagnostic modes which both provide access to the trouble codes. See accessing Trouble Codes for more information.Preparatory Conditions
- Battery voltage 11 Volt minimum
- Closed throttle position (CTP) switch full closed
- Transmission in neutral position
- All auxiliary equipment, including air conditioning, switched OFF
- Engine at normal operating temperature
Accessing Trouble Codes
Self-Diagnosis – Normal Mode- Switch ignition ON. Do NOT start engine.
- Check MIL illuminates
- Switch ignition OFF
- Cressida – jump DLC terminals TE1 and E1 with a short lead 1 or 2
- Camry – jump DLC terminals TE1 and E1 with a short lead 1 or 3
- Count MIL flashes and compare with trouble code table below
- First flashes of .5 second duration indicate ‘tens’, after a 1.5 second pause, next flashes of .5 second duration indicate ‘units’
- A 2.5 second pause occurs between codes
- After a 4.5 second pause, trouble codes will be repeated
- Switch ignition OFF
- Remove jump lead
- Carry out preparatory conditions
- Jump DLC terminals TE2 and E1 with a short lead 1
- Switch ignition ON. Do NOT start engine
- Check MIL is flashing to confirm test mode is operating
- NOTE: Test mode will not be activated if the DLC terminals are connected after the ignition switch is turned ON.
- Start the engine
- Drive vehicle over 10 mph to simulate possible fault conditions
- Stop vehicle
- Jump DLC terminals TE1 and E1 with a short lead 1
- Count MIL flashes and compare with trouble code table below
- Switch ignition OFF
- Remove jump leads

Clearing Trouble Codes
- Ensure ignition switched OFF
- Cressida – Remove EFI fuse (20A) from underhood fusebox 6
- Wait 20 seconds
- Camry – Remove EFI fuse (15A) from underhood fusebox 7
- Wait 30 seconds
- Reinstall fuse
- Repeat accessing procedure to ensure no data remains in ECM fault memory
