G531332t111 : CHECK THE STARTER RELAY TO ECM CIRCUIT FOR SHORT CIRCUIT TO GROUND
1. Key off.
2. Remove the starter relay.
3. Measure the resistance between:

Starter relay base Battery
Pin 02 Negative terminal

- Is the resistance less than 10,000 ohms?

-> YES
REPAIR the short circuit. CLEAR the DTC and test the system for normal operation.

G531332t133 : CHECK THE STARTER RELAY TO ECM CIRCUIT FOR HIGH RESISTANCE
1. Disconnect the ECM electrical connector, EC300.
2. Measure the resistance between:

Starter relay base ECM connector EC300,
harness side
Pin 02 Pin 51

- Is the resistance greater than 5 ohms?

-> YES
REPAIR the high resistance circuit. CLEAR the DTC and test the system for normal operation.
