WARNING: This page is about a different car, the 1998 Honda Prelude. However, it is still accessible from the selected car via links, so may be relevant.
- Turn ignition off. Check continuity in communication line between passenger's multiplex control unit harness connector terminal B1 (Pink wire) and driver's multiplex control unit harness connector terminal D1 (Pink wire). See WIRING DIAGRAMS . If continuity exists, go to next step. If continuity does not exist, repair open in Pink wire. After repairs, recheck DTCs.
- Turn ignition on. Check voltage in communication line between ground and passenger's multiplex control unit harness connector terminal B1 (Pink wire) and driver's multiplex control unit harness connector terminal D1 (Pink wire). See WIRING DIAGRAMS . Voltage should be 3-10 volts. If voltage is not as specified, go to next step.
- If voltage is greater than 10 volts, check for short to another circuit or poor contact or faulty circuit at connector on receiver side of unit. If voltage is less than 3 volts, check for short to ground or short to another wire in circuit. Check for poor contact or faulty circuit at connector on transmit side of unit. Repair as necessary. After repairs, recheck DTCs.
