Pinpoint Test E: The Flash-To-Pass Feature Is Inoperative
WARNING: This page is about a different car, the 2008 Mercury Mariner and 2008 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.
- E1 VERIFY THE HIGH BEAM HEADLAMP OPERATION
- Key in ON position.
- Place the headlamp switch in the HEADLAMPS ON position.
- Place the multifunction switch in the HIGH BEAM position while observing the headlamps.
- Do the high beam headlamps illuminate?
- YES : Go to E2.
- NO : Go to Pinpoint Test A .
- E2 CHECK THE MULTIFUNCTION SWITCH
- Key in OFF position.
- Disconnect: Multifunction Switch C202
- Connect a fused (5A) jumper wire between the multifunction switch C202-4, circuit CLF27 (GN/BN), harness side and the multifunction switch C202-8, circuit GD114 (BK/BU), harness side.
- Do the high beams illuminate?
- YES : REMOVE the jumper wire. INSTALL a new multifunction switch. REFER to STEERING COLUMN SWITCHES article. TEST the system for normal operation.
- NO : REMOVE the jumper wire. Go to E3.
- E3 CHECK CIRCUIT CLF27 (GN/BN) FOR AN OPEN
- Disconnect: SJB C2280b
- Measure the resistance between the multifunction switch C202-4, circuit CLF27 (GN/BN), harness side and the SJB C2280b-43, circuit CLF27 (GN/BN), harness side.
- Is the resistance less than 5 ohms?
- YES : Go to E4.
- NO : REPAIR the circuit. TEST the system for normal operation.
- E4 CHECK FOR CORRECT SJB OPERATION
- Disconnect all the SJB connectors.
- Check for:
- corrosion
- damaged pins
- pushed-out pins
- Connect all the SJB connectors and make sure they seat correctly.
- Operate the system and verify the concern is still present.
- Is the concern still present?
- YES : INSTALL a new SJB. REFER to MULTIFUNCTION ELECTRONIC MODULES article. TEST the system for normal operation.
- NO : The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector.
