C - Warning Lamp Does Not Come "ON" Steady

Circuit Description:
When the ignition switch is first turned ON, ignition 1 voltage is applied from the MA01 meter fuse to the AIR BAG warning lamp which is connected to SRS warning lamp, terminal 7.The SRS-1 fuse apply system voltage to the ignition 1 inputs, terminals 12.The SDM responds by flashing the AIR BAG warning lamp seven times. If ignition 1 voltage is more than 16 volts, the AIR BAG warning lamp will be still OFF solid with no DTCs set.

Chart Test Description:
Number(s) below refer to step number(s) on the diagnostic chart:
1. This test decides whether power is available to SDM warning lamp power feed circuit.
2. This test determines whether the voltage is present in the warning lamp circuit.
3. This test determines it the malfunction is in the instrument cluster.
4. This test checks for open in the warning lamp circuitry.
5. This test isolates the IB04-GRN circuit and checks for a short in the IB04-GRN circuit to B+.
8. This test checks for a short from the SDM warning lamp power feed circuit to ground.
9. This test determines whether the short to ground is due to a short in the wiring.
