Starter battery relay control short circuit to battery.
â–¶ How to fix
• Check wiring (to starter battery relay) • Check connectors (to starter battery relay) • Check starter battery relay • Measure the relay voltage between signal and ground.
What you'll see
No driver-visible symptom recorded.
System reaction
The starter battery will always be connected.
Diagnostic depth
Detection
Impermissible signal from the starter battery relay (located in the battery box). The sensor voltage level is too high during passive diagnosis (while the diagnostic voltage is low).
Possible cause
• Defect wiring - short circuit to battery • Defect connectors • Defect starter battery relay
