Toyota Camry (XV70): Indicator (Green) Circuit Short to Ground (B157111,B157113)
DESCRIPTION
This DTC is set when the DCM (telematics transceiver) detects an open or short in the manual (SOS) switch green indicator circuit of the manual (SOS) switch. The manual (SOS) switch green indicator illuminates after the engine switch is turned on (IG).
If the safety connect system is not active, the manual (SOS) switch green indicator will turn off.
If the safety connect system is active, the manual (SOS) switch green indicator will blink while communicating with the call center.

INSPECT ROOF CONSOLE BOX SUB-ASSEMBLY (MANUAL (SOS) SWITCH) (GREEN INDICATOR) |
| (a) Remove the roof console box sub-assembly (manual (SOS) switch). Click here |
|
(b) Connect 2 dry-cell batteries (1.5 V each) in series.
(c) Connect a positive (+) lead from batteries to terminal 11 (IND2) and a negative (-) lead to terminal 16 (GND3) of the roof console box sub-assembly (manual (SOS) switch) connector.
(d) Check if the manual (SOS) switch green indicator comes on.
OK:
Manual (SOS) switch green indicator illuminates.
