Entering the Diagnostics Mode
Complete the following steps in order to enter the diagnostics mode:1. Ensure that the BCM is in the feature customization mode.
2. Turn the ignition switch from the ACC position to the OFF position, then back to the ACC position within 1 second.
Perform the following procedure in order to confirm the BCM has entered the diagnostics mode:
1. Ensure that all of the vehicle doors are closed.
2. Open and close any one of the doors.
3. Fasten and release the driver seat belt.
The BCM sounds the chime when it receives an input signal such as opening a door or fastening the drivers seat belt when the BCM is in the diagnostics mode.
The following actions occur when the diagnostics mode is entered:
^ The BCM flashes the fasten belts indicator.
^ The BCM sounds the chime a number of times equal to the DTCs that are stored in the memory.
If no DTCs are stored the BCM does not flash the fasten belts indicator nor sounds the chime.
The BCM flashes and sounds the first DTC with the lowest number. The BCM pauses and continues with the next DTC until all the DTCs are read. Once all the DTCs are read, the BCM repeats this sequence 3 times.
If there are DTCs in the memory, record the DTCs.
