NOTE:
- Use the schematics to verify the items listed below:
- The control module's B+, and ground circuits.
- The control module terminal numbers.
- Some control module ground circuits may require up to 20 min after the ignition is turned Off before achieving a resistance reading of less than 5 Ω. In most cases the readings will drop below 20 Ω within 1 min indicating the control modules are going to sleep.
- Ignition Off, disconnect the connector(s) at the appropriate control module.
- Verify a test lamp illuminates between each ground circuit terminal and B+
- If the test lamp does not illuminate
Repair the open/high resistance on circuit or the ground connection.
- Go to next step: If the test lamp illuminates
- If the test lamp does not illuminate
- Ignition ON.
- Verify a test lamp illuminates between each B+ circuit terminal and ground.
- If the test lamp does not illuminate and the circuit fuse is good
- Test the B+ circuit for an open/high resistance.
- If an open/high resistance is found, repair the fault on the circuit.
- Go to next step: If an open or high resistance is not found
- Verify the fuse is not open and there is voltage at the fuse.
- If the test lamp does not illuminate and the circuit fuse is open
- Test the B+ circuit a short to ground
- If a short to ground is found, repair the fault on the circuit.
- Go to next step: If a short to ground is not found
- Replace the control module.
- Go to next step: If the test lamp illuminates
- Verify voltage at each B+ circuit terminal is within 1 V of the C1 Battery voltage.
- If not the specified value
Repair the high resistance on B+ circuit.
- Go to next step: If the specified value
- If not the specified value
- Verify a test lamp illuminates between each ignition circuit terminal and ground.
- If the test lamp does not illuminate and the circuit fuse is good
- Test the ignition circuit for an open/high resistance.
- If an open/high resistance is found, repair the fault on the circuit.
- Go to next step: If an open or high resistance is not found
- Verify the fuse is not open and there is voltage at the fuse.
- If the test lamp does not illuminate and the circuit fuse is open
- Test the ignition circuit a short to ground
- If a short to ground is found, repair the fault on the circuit.
- Go to next step: If a short to ground is not found
- Replace the control module.
- Go to next step: If the test lamp illuminates
- Verify voltage at each ignition circuit terminal is within 1 V of the C1 Battery voltage.
- If not the specified value
Repair the high resistance on ignition circuit.
- Go to next step: If the specified value
- If not the specified value
- Replace the control module.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
