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.
Circuit/System Verification
The Diagnostic Indicator Pattern 1 is a confirmation that the object alarm system has successfully entered the diagnostic mode. If the Diagnostic Indicator Pattern 1 does not display after an attempt to enter the diagnostic mode, it may be as a result of not entering the system diagnostic mode successfully or a RPA diagnostic input circuit fault is present. After the Diagnostic Indicator Pattern 1 is displayed, observe the RPA display for the next Diagnostic Indicator Pattern displayed. The indicator pattern displayed after the Diagnostic Indicator Pattern 1 is the diagnostic indicator pattern that actually needs be diagnosed. Proceed to the appropriate Diagnostic Pattern in this table. Refer to Diagnostic Trouble Code (DTC) Displaying .
