PINPOINT TEST 7: FLASH CODE 2 - STOPLAMP SWITCH CIRCUIT FAILURE
Normal Operation
When the speed control actuator carries out the self-test, a voltage signal is sent through circuit (V/W). Circuit (V/W) carries the signal to the high mounted stoplamp, which then is routed to ground. If the signal fails to be grounded, flash code 2 is set by the speed control actuator.
Possible Causes
- Wiring, terminals or connectors
- High mounted stoplamp
- Stoplamp switch
- Speed control actuator
Diagnostic Procedure
CAUTION: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.
