: P1245. IGNITION SWITCH CRANK SIGNAL

G92429t170 : CHECK THE START INPUT TO THE ECM
1. Move the gear selector to the N position.
2. Disconnect the ECM electrical connector EN16.
3. Remove the starter relay from the power distribution fuse box.
4. Turn the ignition switch to the CRANK position.
5. Measure the voltage between EN16 pin 6 (Y) and GROUND.

- Is the voltage greater than 10 volts?

-> Yes

-> No
REPAIR the circuit between the ECM and the battery. CLEAR the DTC. TEST the system for normal operation.
This circuit includes the ignition switch and the power distribution fuse box. [Fuse 28].

G92429t171 : CHECK THE START INPUT TO THE STARTER RELAY
1. Turn the ignition switch to the START position and hold.
2. Measure the voltage between the starter relay base (R10) pin 1 and GROUND.

- Is the voltage greater than 10 volts?

-> Yes

-> No
REPAIR the circuit between the starter relay base and the battery. CLEAR the DTC. TEST the system for normal operation.
This circuit includes the ignition switch and the power distribution fuse box

G92429t172 : CHECK THE START INPUT WIRE FOR SHORT TO BATTERY AT ECM
1. Turn the ignition switch to the ON position.
2. Measure the voltage between EN16 pin 6 (Y) and GROUND.

- Is the voltage greater than 10 volts?

-> Yes
REPAIR the short circuit. CLEAR the DTC. TEST the system for normal operation.

-> No

G92429t173 : CHECK THE START INPUT WIRE FOR SHORT TO BATTERY AT RELAY
1. Turn the ignition switch to the ON position.
2. Measure the voltage between the starter relay base pin 1 and GROUND.

- Is the voltage greater than 10 volts?

-> Yes
REPAIR the short circuit. CLEAR the DTC. TEST the system for normal operation.

-> No

G92429t200 : CHECK THE STARTER RELAY INPUT FROM THE ECM FOR CONTINUITY
1. Measure the resistance between EN16 pin 41 (GO) and relay base pin 2.

- Is the resistance less than 5 ohms?

-> Yes

-> No
REPAIR the open circuit. CLEAR the DTC. TEST the system for normal operation.

G92429t201 : CHECK THE STARTER RELAY INPUT FROM THE ECM FOR SHORT TO GROUND
1. Disconnect ignition switch electrical connector IP18.
2. Measure the resistance between EN16 pin 41 (GO) and GROUND.

- Is the resistance less than 10,000 ohms?

-> Yes
REPAIR the short circuit. CLEAR the DTC. TEST the system for normal operation.

-> No

G92429t202 : CHECK THE STARTER RELAY INPUT FROM THE ECM FOR SHORT TO BATTERY
1. Measure the voltage between the starter relay base pin 2 and GROUND.

- Is the voltage greater than 1 volt?

-> Yes
REPAIR the short circuit. CLEAR the DTC. TEST the system for normal operation.

-> No
INSTALL a new starter relay. CLEAR the DTC. TEST the system for normal operation. If the DTC is repeated, INSTALL a new ECM. Before replacing an ECM, contact dealer technical support.
