8E - 36 INSTRUMENT PANEL AND GAUGES		Ä

Fig. 30 Cluster Connector

CONDITION: CLUSTER ASTERISK (*) FLASHES, CLUSTER DISPLAYS NOT INDICATING CORRECT DATA.

PROCEDURE

CCD bus problem. Use the Body Chassis Diagnostic Manual to diagnose CCD Bus.

CONDITION: SPEEDOMETER AND ODOMETER ARE INOPERATIVE OR OPERATES INTERMITTENTLY

PROCEDURE

(1)If speedometer reads 0, or odometer is blank, and cluster asterisk is flashing, use the Body Chassis Diagnostic Manual to diagnose CCD Bus problem.

(2)If cluster asterisk is not flashing, check for defective distance sensor or distance sensor wiring.

CONDITION: OIL GAUGE, FUEL GAUGE, TEMPERATURE GAUGE, OR VOLTAGE GAUGE INOPERATIVE

PROCEDURE

If any gauge gives no indication and cluster asterisk is flashing, use the Body Chassis Manual to diagnose CCD Bus problem.

If cluster asterisk is not flashing:

(1) Check for defective sending unit or wiring.

(a)Sending units and wiring can be checked by grounding the connector leads, at the sending unit, in the vehicle.

(b)With the ignition in the ON position, a grounded input will cause the oil, fuel, or temperature gauge to read maximum.

(2)If the problem is with the oil, temperature, or fuel gauge, check the body controller. If the problem is with the voltage gauge, check the engine controller operation.

CONDITION: CLUSTER DISPLAY DOES NOT DIM WHEN HEADLAMP SWITCH IS ACTIVATED AND RHEOSTAT ROTATED

PROCEDURE

If the cluster asterisk is flashing, Refer to the Body Chassis Diagnostic Manual to diagnose the CCD Bus.

If the cluster asterisk is not flashing:

(1)Check fuses in headlamp circuit.

(2)Check for loose connections or defective wiring for headlamp switch to body controller.

(3)Check for defective headlamp switch. The electronic instrument cluster receives the display intensity status from the body controller via the CCD Bus.
