1 | • Disconnect car-navigation unit connector (16-pin). • Jack up vehicle and run engine at low speed. • Measure voltage at the following terminal of car-navigation unit connector (16-pin): – Terminal 1H (Vehicle speed signal) • Is voltage approx. 2.5 V (reference)? Note • Vehicle speed signal is in electrical pulses of approx. 0 V to 5 V. | Yes | Replace car-navigation unit (available at Clarion service center) or get it repaired at Panasonic service center, then go to Step 4.
No | Go to next step.
2* | • Disconnect ABS HU/CM connector (28-pin) or DSC HU/CM connector (34-pin). • Is there continuity between car-navigation unit connector (16-pin) terminal 1H and ABS HU/CM connector (28-pin) terminal V, or car-navigation unit connector (16-pin) terminal 1H and DSC HU/CM connector (34-pin) terminal AA? | Yes | Go to next step.
No | Repair wiring harness between car-navigation unit and ABS HU/CM, or car-navigation unit and DSC HU/CM, then go to Step 4.
3 | • Inspect wiring harness between car-navigation unit connector (16-pin) terminal 1H and ABS HU/CM connector (28-pin) terminal V, or car-navigation unit connector (16-pin) terminal 1H and DSC HU/CM connector (34-pin) terminal AA for short to ground. • Is there short to ground? | Yes | Repair wiring harness between car-navigation unit and ABS HU/CM, or car-navigation unit and DSC HU/CM, then go to next step.
No | Replace instrument cluster, then go to next step.
4 | • Does vehicle locator mark operate normally? | Yes | Complete troubleshooting, then explain repairs to customer.
