Specs & OE: 12V plug-in micro ISO relay, 5-pin SPDT (“1192” footprint), blade terminals. Function: ECM/ECU/PCM power control in the engine bay fuse block. Replaces OE# 13306942 (superseded by 13468935); also cross-refs 56-2728, 1R3310, 16152. Size and pin-out match the original; no programming. Match your old relay's 5-blade layout before purchase.

Disconnect the negative battery terminal first and follow your owner's/service manual for slot orientation. A failing ECM/PCM relay may cause hard/no-start, intermittent stalling, loss of ECM power, or related U0100/U0101-type communication DTCs.

Supersession & Interchange: 13306942 is superseded by 13468935 per GM parts databases; using 13468935 for lookup yields the same micro-relay used on the above platforms. When replacing, match the 5-blade “1192” micro ISO footprint.
Complementary Items (sold separately): For a complete under-hood refresh, pair with Compatible with GM 13500126 black multi-purpose relay (commonly used for wiper and auxiliary circuits) and Compatible with GM 15328864 A/C compressor relay (4-pin). Replacing these related relays together can help eliminate intermittent issues with ECM, A/C, and wiper loads in one service.
