Test G: The Speed Dependent Interval Mode Does Not Operate Correctly
PINPOINT TEST G: THE SPEED DEPENDENT INTERVAL MODE DOES NOT OPERATE CORRECTLYNormal Operation
The smart junction box (SJB) receives vehicle speed information from the instrument cluster (IC) over the communication network. When any intermittent wiper mode is selected except INT 1, the SJB will gradually increase or decrease the delay between wipes based on vehicle speed.
The speed dependent feature is easiest to verify in the INT 2 position. With the vehicle at a standstill and the multi-function switch in the INT 2 position, the wipers should operate once every 10 seconds. As vehicle speed increases, the delay between wipes will gradually shorten. For example, by the time the vehicle reaches 100 km/h (62 mph), the wipers should operate every 5 seconds. Speed dependent operation is similar in INT 3, INT 4 and INT 5 modes.
This pinpoint test is intended to diagnose the following:
- IC
- SJB
