Jetta GLS VR6 V6-2.8L (AFP) (2001)
If the display does not change:
-
Disconnect 4-pin harness connector from brake light switch and brake pedal switch.
-
Measure resistance between terminals -1- + -4- of switch.
Specified value with brake pedal not depressed: infinity ohms
Specified value with brake pedal depressed: max. 1.5 ohms
-
Measure resistance between terminals -2- + -3- of switch.
Specified value with brake pedal not depressed: 1.5 ohms
Specified value with brake pedal depressed. max. infinity ohms
If the specified values are not obtained:
-
Replace brake light switch -F- and brake pedal switch -F47-
-
Check DTC memory. If necessary, repair any malfunctions and erase DTC memory. Refer to "On Board Diagnostic (OBD)/Diagnostic Trouble
Code (DTC) Memory, Checking and Erasing (Scan Tool Functions 02 and 05)" under "Powertrain Management/Fuel Delivery and Air
Induction/Fuel Injector", See: Powertrain Management/Fuel Delivery and Air Induction/Fuel Injector/Testing and Inspection
-
Display readiness code1. Refer to "On Board Diagnostic (OBD)/Readiness Code/Displaying" under "Powertrain Management/Fuel Delivery and
Air Induction/Fuel Injector", See: Powertrain Management/Fuel Delivery and Air Induction/Fuel Injector/Testing and Inspection
If DTC memory has been erased or the Engine Control Module (ECM) was disconnected from permanent battery (B+) voltage, the readiness code
must be generated again. Refer to "On Board Diagnostic (OBD)/Readiness Code/Generating" under "Powertrain Management/Fuel Delivery and
Air Induction/Fuel Injector", See: Powertrain Management/Fuel Delivery and Air Induction/Fuel Injector/Testing and Inspection
If the specified values are obtained:
-
Connect multimeter to measure voltage between terminal -1- and Ground (GND).
Specified value: at least 11.5 V
-
Connect multimeter to measure voltage between terminal -2- and Ground (GND).
-
Switch ignition on.
Specified value: at least 11.5 V
