Diagnostic Test
1. (F942) FUSED IGNITION SWITCH OUTPUT CIRCUIT SHORT TO GROUNDTurn the ignition off.
Remove and inspect the #13 Fuse in the Junction Block.
If the fuse is open, replace with proper rated fuse.
Turn the ignition on for 1 minute.
Turn the ignition off.
Remove and inspect the #13 Fuse in the Junction Block.
Is the fuse open?
Yes
- Repair the (F942) Fused Ignition Switch Output circuit for a short to ground.
- Perform BODY VERIFICATION TEST - VER 1. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE)
No
- Go To2
2. (F942) FUSED IGNITION SWITCH OUTPUT CIRCUIT OPEN
Turn the ignition off.
Disconnect the Instrument Cluster harness connector.
Turn the ignition on.
Measure the voltage between (F942) Fused Ignition Switch Output circuit and ground.
Is the voltage above 10.5 volts?
Yes
- Go To3
No
- Repair the (F942) Fused Ignition Switch Output circuit for an open.
- Perform BODY VERIFICATION TEST - VER 1. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE)
3. (Z18) INSTRUMENT CLUSTER GROUND CIRCUIT OPEN
Turn the ignition off.
Disconnect the Instrument Cluster harness connector.
Measure the resistance between ground and the (Z18) Instrument Cluster Ground circuit.
Is the resistance below 5.0 ohms?
Yes
- Replace and configure the Instrument Cluster in accordance with the Service Information.
- Perform BODY VERIFICATION TEST - VER 1. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE)
No
- Repair the (Z18) Instrument Cluster Ground circuit for an open.
- Perform BODY VERIFICATION TEST - VER 1. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE)
