COMBINATION METERS
Self-Diagnosis Mode of Combination Meter
INFOID:0000000003533486
SELF-DIAGNOSIS FUNCTION
The following items can be checked during Combination Meter Self-Diagnosis Mode.
• Gauge sweep and present gauge values.
• Illuminates all odometer, fuel, and engine temperature segments.
• Illuminates all micro controlled lamps/LE D's regardless of switch configuration.
• Displays estimated present battery voltage.
• Displays seat belt buckle switch LH status.
HOW TO INITIATE COMBINATION METER SELF- DIAGNOSIS MODE
NOTE:
Once entered, Combination Meter Self-Diagnosis Mode will function with the ignition switch in ON or START.
Combination Meter Self-Diagnosis Mode will exit upon turning the ignition switch to OFF or ACC.
To initiate Combination Meter Self-Diagnosis Mode, refer to the following procedure.
1. Turn the ignition switch ON, while holding the odom eter/trip meter switch for 5 - 8 seconds. When the
diagnosis function is activated the odometer/trip meter will display tESt.
NOTE:
Check combination meter power supply and ground ci rcuit when self-diagnosis mode of combination
meter does not start. Refer to DI-16, "
Power Supply and Ground Circuit Inspection". Replace combination
meter if normal. Refer to IP-10, "
Removal and Installation".
