Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Diagnostic Code Output: Notes
The ECU stores component failure information for the TCCS under a related trouble code which can be recalled for diagnosis and repair. A malfunction is indicated by the "CHECK ENGINE" warning light blinking a number of times equal to the malfunction code indication, with a 2.5 second delay between each indication.
The diagnostic code series will be repeated as long as the engine check connector terminals T - E1 are shorted. In the event of a number of trouble codes, indication will begin from the smaller value and continue to the larger in order.
