PINPOINT TEST R : The Air Bag Warning Indicator Is Never or Always On: Notes

Diagnostic Overview 

Refer to Instrument Panel Cluster (IPC) , Air Bag Warning Indicator.

Normal Operation and Fault Conditions 

If the air bag indicator lamp request message is missing for less than 5 seconds, the IPC defaults the air bag warning indicator to its last state (on or off) based upon the last known good message received.

If the air bag indicator lamp request message is missing or is deemed invalid for 5 seconds or longer, the IPC sets DTC U0151:00 in continuous memory and defaults the air bag warning indicator on.
