Check Engine Code Instructions

Directions for checking the Codes

 

1) Remove the kick panel just beside the left foot rest on the driver's side.

2) Locate blue wires.

3) Locate black connector. Hold it notch up.

4) With ignition off, insert one of the wires into top row, 2nd pin from left.

5) Turn key to on position, but do not start the car.

6) Watch blinky check engine light on dashboard. Count blinks. Long blinks = 10, Short blinks = 1.

7) Keep watching blinky light until you get mesmorized.

 

 

To clear codes (after problem has been resolved):

1) With engine off, stick the blue wires to 1st and 2nd pin in the top row counting from left on the

 

black connector, with notch facing up.

2) Start car. Shut off car. Remove pins.

3) Read codes to make sure they are clear. No codes = steady blinks at 1/4 second intervals.

To perform the TCU self diag test for EXISTING problems

 

1) Warm up engine by driving at speeds greater than 12mph.

2) Stop vehicle and turn ignition switch OFF.

3) Turn ignition switch ON and make sure POWER indicator lamp comes on.

4) Turn ignition switch OFF.

5) Move selector lever to D and turn manual switch ON.

6) Turn ignition switch ON.

7) Move selector lever to "3" and turn manual switch OFF.

8) Move selector level to "2" and turn manual switch ON.

9) Move selector lever to "1" and turn manual switch OFF.

10) Partially depress accelerator pedal (to turn idle switch off).

11) Check code as displayed on POWER light. Blinking once every 1/4sec is normal.
