Standard resistance:
Below 1 Ohms
NG -- REPLACE FUSE
OK -- Continue to next step.

2. CHECK WIRE HARNESS (MULTI-DISPLAY - BATTERY AND BODY GROUND)




(a) Disconnect the M13 connector.
(b) Measure the resistance of the wire harness side connector.
Standard resistance:





(c) Measure the voltage of the wire harness side connector.
Standard voltage:





HINT:
- *1: for 4 Connector type
- *2: for 3 Connector type

NG -- REPAIR OR REPLACE HARNESS AND CONNECTOR
OK -- PROCEED TO NEXT CIRCUIT INSPECTION SHOWN IN PROBLEM SYMPTOMS TABLE
