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.
Multiple Gauge Circuit Testing
If fuel, voltage and tachometer gauges appear to be malfunctioning, remove the cluster assembly. Check for good pin contact between wiring harness and printed circuit board. If there is good contact, check for ignition voltage at Black connector cavity "C". See Figure -Figure . If there is ignition voltage, check for continuity between wiring harness Black connector cavity "H" and ground. If there is continuity, replace printed circuit board.
If temperature, oil pressure and speedometer gauges appear to be malfunctioning, remove cluster assembly. Check for good contact between wiring harness and printed circuit board. If there is good contact, check for ignition voltage at Red connector cavity "J". If there is voltage, check for continuity at Black connector cavity "H". If there is continuity, replace printed circuit board.
