(1) Disconnect the theft-alarm horn relay connector C-100 and 

measure at the relay box side.

(2) Measure the voltages between terminals 1, 2 and ground.

• The measured value should be approximately 12 volts 

(battery positive voltage).

Q: Does the measured voltage correspond with this range?

YES : Go to Step 7.
NO :  Go to Step 5.

STEP 5. Check theft-alarm horn relay connector C-100 for 
loose, corroded or damaged terminals, or terminals 
pushed back in the connector.

Q: Is theft-alarm horn relay connector C-100 in good 

condition?
YES : 
Go to Step 6.
NO :  Repair or replace it. Refer to GROUP 00E, Harness
