7GR-FKS ENGINE CONTROL  SFI SYSTEM  P061512  Starter Relay Circuit Short to Battery  


MONITOR DESCRIPTION

While the engine is being cranked, positive battery voltage is applied to terminal STA of the ECM. If the ECM detects the starter control (STA) signal while the vehicle is being driven, it determines that there is a malfunction in the STA circuit. The ECM then illuminates the MIL and stores the DTC.

This monitor runs when the vehicle is driven at 20 km/h (12.43 mph) or more for 20 seconds or more.

DTC No. Detection Item DTC Detection Condition Trouble Area MIL Memory Note
P061512 Starter Relay Circuit Short to Battery All of the following conditions are met, and battery voltage of 10.5 V or higher is applied to the ECM for 20 seconds (1 trip detection logic):

(a) The vehicle speed is 20 km/h (12.43 mph) or more.

(b) The engine speed is 1000 rpm or higher.

(c) The STA signal is on.

The purpose of this step is to check for STARTER relay terminal voltage under abnormal conditions.


a.

Remove the STARTER relay from the No. 1 engine room relay block and junction block assembly.


b.

Turn the ignition switch to ON.


c.

Measure the voltage between STARTER relay terminal 2 and body ground.

HINT:
·

Make a note of the measured voltage as it will be necessary for the inspecting the change in voltage in the next step. As the next step should be conducted under the same conditions, keep the ignition switch ON and do not install the STARTER relay.

·

DTCs may be stored during this inspection. Check for DTCs and clear them using the GTS.

·

If any voltage was measured with the ignition switch ON, one of the following malfunctions is suspected:

-

Short to +B in the circuit of a connected ECU or the switch.

-

Short to +B in the wire harness.
