DTC C1016: Stop Lamp Switch Circuit FailureS7RS0B4604026
Wiring Diagram9
Check serial data circuit
1) Turn ignition switch to OFF position.
2) Check proper connection at “E85-33” (“PPL/WHT” wire)
terminal for serial data circuit.
3) If OK, then check resistance between “E85-33” (“PPL/ WHT” wire) terminal and “PPL/WHT” wire terminal (2) for
serial data circuit in DLC (1).
Is resistance 1
Ω or less? Substitute a known-
good ESP
® hydraulic
unit / control module
and recheck. Check high resistance
or open in “PPL/WHT”
wire circuit for electronic
stability program. If
circuit is OK, substitute
