DIAGNOSIS
Required Special Tools:
-
MB991223: Test Harness Set
-
MB991502: Scan Tool (MUT-II)
STEP 1. Check the hazard warning light switch.
Q: Is the hazard warning light switch in good condition?
YES: Go to Step 2.
NO: Replace the hazard warning light switch. If the equipment, which are described in "CIRCUIT OPERATION", work normally, the input signal
from the hazard warning light switch should be normal.
STEP 2. Measure at hazard warning light switch connector C-10 in order to check the ground circuit to the hazard warning light switch.
1. Disconnect hazard warning light switch connector C-10, and measure at the wiring harness side.
2. Measure the resistance value between terminal 2 and ground.
-
The measured value should be 2 ohm or less.
Q: Does the measured resistance value correspond with this range?
YES: Go to Step 5.
NO: Go to Step 3.
