Pinpoint Test F: The Flash-To-Pass Feature Is Inoperative
WARNING: This page is about a different car, the 2007 Ford Ranger. 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.
- F1 CHECK THE HIGH BEAM OPERATION
- Key in OFF position.
- Place the headlamp switch in the HEADLAMPS ON position.
- Place the multifunction switch in the HIGH BEAM position.
- Do the high beams illuminate?
- YES : Go to F2.
- NO : Go to Pinpoint Test C .
- F2 CHECK FOR VOLTAGE TO THE MULTIFUNCTION SWITCH
- Place the headlamp switch in the OFF position.
- Disconnect: Multifunction Switch C202b
- Measure the voltage between the multifunction switch C202b-6, circuit SBP23 (WH/RD), harness side and ground.
- Is the voltage greater than 10 volts?
- YES : INSTALL a new multifunction switch. REFER to STEERING COLUMN SWITCHES article. TEST the system for normal operation.
- NO : Go to F3.
- F3 CHECK CIRCUIT SBP23 (WH/RD) FOR AN OPEN
- Disconnect: SJB C2280b
- Measure the resistance between the multifunction switch C202b-6, circuit SBP23 (WH/RD), harness side and the SJB C2280b-1, circuit SBP23 (WH/RD), harness side.
- Is the resistance less than 5 ohms?
- YES : Go to F4.
- NO : REPAIR the circuit. TEST the system for normal operation.
- F4 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.
